Heat Exchangers

 Heat exchangers are essential components in various industrial processes. They are designed to transfer heat between two or more fluids, without allowing them to mix. This process is crucial for maintaining optimal temperatures and increasing energy efficiency. Heat exchangers can be found in a wide range of applications, including power plants, chemical plants, refrigeration systems, and even in everyday appliances like air conditioners and car radiators.

The basic principle behind heat exchangers is the transfer of thermal energy from a hot fluid to a cooler fluid. This is achieved through a combination of conduction, convection, and radiation. The fluids flow through separate channels or passages within the heat exchanger, ensuring that they remain isolated from each other. As the hot fluid passes through one set of channels, it heats up the walls of the heat exchanger. The cooler fluid, flowing through another set of channels, absorbs this heat and gets heated up in the process. The two fluids never come into direct contact, preventing any contamination or mixing.

Heat exchangers come in various designs and configurations, depending on the specific application and requirements. Some common types include shell and tube heat exchangers, plate heat exchangers, and finned tube heat exchangers. Each type has its own advantages and limitations, and the choice of heat exchanger depends on factors such as the temperature and pressure of the fluids, the desired heat transfer rate, and the available space. Regardless of the type, heat exchangers play a crucial role in many industries, helping to optimize processes, reduce energy consumption, and increase overall efficiency.

The Ins and Outs of Heat Exchangers

Heat exchangers play a vital role in the operational efficiency and effectiveness at every processing facility in which heat is essential, whether it is an oil refinery or a biomass power plant. As energy efficiency importance grows, the role of heat exchangers will become even greater, their technologies more advanced.

The idea is simple, but the system designs and inner workings of heat exchange are magnificently brilliant. Heat is generated for and in various industrial processes, and were it not for heat exchangers, massive amounts of thermal energy would be wasted. For instance, boilers combust fuels such as biomass to generate heat to produce steam for powering a turbine in producing electricity. Once that steam does its job, it still has a lot of thermal energy, some of which can be transferred via a vapor-to-liquid shell-and-tube heat exchanger to raise the boiler feedwater temperature. This serves multiple purposes, including cooling down the steam to avoid thermal shock on the boiler’s steam drum, and reducing the heat load needed to raise the temperature of the boiler feedwater. This is one of many heat exchanger applications at Koda Energy, a biomass combined-heat-and-power (CHP) plant in Shakopee, Minnesota, says Stacy Cook, general manager. Koda Energy, a partnership between Rahr Malting Co. and Shakopee Mdewakanton Sioux Community, began commercial operations in 2009 and produces 500 megawatt-hours of electricity and 2,500 Btu of thermal energy daily from agriculture waste and wood chips. The plant has only the world’s second power boiler to use wall-mounted burners to combust biomass in suspension, meaning airborne burning of biomass. About 25 percent of Koda Energy’s total electrical output is provided to Rahr Malting, slightly more than 50 percent is sold to Xcel Energy (i.e., the grid), and the remainder sustains operations at the CHP plant. And 100 percent of its thermal output is provided to Rahr Malting. The electricity and energy is used to malt barley for beer at the largest site producer of malted barley in the world. Common sources of waste heat in industry, according to Kevin McGinnis, sales director for heavy industries and mining at Kelvion—the successor to Germany-based GEA Heat Exchangers Group—include turbines, dryers, kilns, incinerators, boilers and flue gas from heaters or burners, to name a few. “In general, waste heat can be captured with various types of heat exchangers and used for various applications,” McGinnis says, “including combustion air preheating; heating a facility, plant, building or home; boiler feedwater preheating; heating a process fluid for another application; or even for the ORC process.” ORC stands for organic Rankine cycle, the thermodynamic cycle using water as a working fluid that provides 85 percent of the world’s electricity production, according to Turboden. Numerous heat exchanger companies exist, many specializing in particular types. Kelvion offers its customers one of the world’s largest product portfolios in the field of heat exchangers, McGinnis says. “It includes individual solutions for practically all conceivable applications and complex environmental conditions, including plate, shell-and-tube, finned-tube and refrigeration heat exchangers, and modular cooling tower systems.” Another big name in heat exchange is Alfa Laval. Wes Crozier, product manager, has been with the Sweden-based company for nearly 30 years in various roles. “In the area of heat transfer, we have gasketed plate heat exchangers for liquid-to-liquid and vapor-to-liquid, air coolers for air-to-liquid, fully welded heat exchangers for high pressures and temperatures, a specialty spiral heat exchanger for extreme fouling services, as well as more niche products,” Crozier says. Netherlands-based HeatMatrix developed what Paul van Dillen, director of global sales and marketing, calls a new generation air-preheater that enables heat recovery from corrosive or fouling gas streams from biomass boilers, refinery furnaces, heaters, ovens or dryers. “This innovative heat exchanger consists of lightweight, corrosion resistant polymer modules, which can be applied at high temperatures and is ideally suited for waste heat recovery from flue gases that are corrosive or have fouling in it,” van Dillen says. HeatMatrix only designs and supplies air-to-air heat exchangers, often used to preheat air from waste heat flue gas streams. At Koda Energy, another shell-and-tube heat exchanger, called a surface condenser, condenses steam flow on the turbine exhaust, Cook says. “The exhaust enters the condenser and puts a vacuum on the exhaust to allow the turbine to run more efficiently,” he says. In addition, a boiler economizer uses combustion gases leaving the boiler to further elevate the feedwater temperature before entering the steam drum on the boiler. “In general, the economizer adds 10 percent efficiency,” Cook says. “We’re taking every opportunity to capture heat.” Kelvion manufactures a welded plate heat exchanger that can be used as a small vacuum condenser or traditional fin/fan technology to serve as an air-cooled condenser. “With our global footprint, we manufacture steam surface condensers and feedwater heaters, both of which are used in the steam cycle,” McGinnis says. “With waste heat generating steam for a steam turbine, Kelvion has all the exchangers in the steam process.” Alfa Laval’s Niagara Wet Surface Air Cooler can also be used to condense the vacuum exhaust steam from the turbine. “The ability to efficiently condense the turbine exhaust steam at low absolute pressures allows for more power generation,” Crozier says. “This is accomplished by a single approach to the ambient wet bulb temperature for cooling.” The prime heat mover at Koda is a very large plate-and-frame heat exchanger. This uses propylene glycol as thermal fluid to transfer heat via piping to Rahr Malting. Then, a similar but smaller unit takes even more leftover Btu from condensate from the steamed glycol heater to gain another 3 percent efficiency. “This was sized to capture the available Btu that were being wasted,” Cook says. “We’re capturing those and putting them back into glycol and useful sales.” Crozier says plate heat exchangers can have a heat transfer coefficient up to four times greater than shell and tube. This, along with its construction, means the footprint can be just 20 percent needed for a shell and tube. “The size advantage is achieved through embossing plates with carefully designed patterns, many of which are patented,” Crozier says. “This embossing creates channels for the fluids to ensure maximum turbulence. This results in maximum efficiency in transferring heat from one medium to the other. In addition, many of our designs are fully counter current, which allow temperature crosses where the outlet temperature of the hot side can be cooler than the outlet temperature of the cold side—very difficult to do with other types of heat exchangers.” Higher temperatures and pressures are being achieved in compact plate heat exchangers, McGinnis says, through new welding technology Kelvion uses, offering alternate designs to traditional shell-and-tube solutions. “Efficiency gains are realized through more effective channel geometries with built-in enhancements,” McGinnis says. Additional plate-and-frame heat exchangers are utilized at Koda for cooling applications, mostly for equipment health. Pumps handle high-temperature liquids, and a portion of these liquids is used in a mechanical shaft seal, so heat is shed to the cooling tower before reaching the pumps so as to not burn up the seals. Another application is to cool the turbine lube oil using circulating water from the cooling tower. “This keeps the turbine lube oil at an acceptable temperature,” Cook says. “We’re running 900-pound steam through the turbine and we need to keep the shaft lubed. If the oil heats up to 900 degrees, it will decompose.” McGinnis says Kelvion has a specialty for cooling the rotating equipment associated with waste heat to energy, manufacturing a range of extended surface shell and tubes and compact plate heat exchangers. Koda also employs a liquid-to-air, radiant air heater using glycol heat to preheat combustion air to avoid acid dew-point corrosion. “If the air temperature drops too low prior to the tubular air heater, it will condense out acid gases on the flue gas side,” Cook says. The plant also uses an air-to-air heat exchanger, called a tubular air heater, which captures waste heat in flue gas. Van Dillen says the heat transfer properties of HeatMatrix’s air-to-air polymer technology, used to capture flue gas heat, is very good in comparison to other, more conventional technologies because of its compactness, thin tube wall, strong honeycomb structure, and 100 percent counter flow. Kelvion’s finned-tube heat exchanger options for air-to-air or air-to-liquid applications include two major types—compact/plate fin coils and spiral-finned tubes—but also finned elliptical tubes. “A specific difference we offer on our spiral fins is our patented ‘groovy’ fin for our spiral-finned tubes,” McGinnis says. “The ‘groovy’ fin enhances heat transfer by turbulating the air more than a regular spiral fin can, which results in better heat transfer and a smaller coil size, making it ideal for replacement coils or in situations where a smaller footprint is needed.” Just like the medium flowing through heat exchangers, technology advancements in the field continue to move the needle. Van Dillen says he believes HeatMatrix’s polymer bundle technology will be a game changer in the industry. While the company currently only manufactures air-to-air exchangers, he says air-to-liquid polymer designs are now under development. “This will be the next focus for HeatMatrix in this field,” van Dillen says. Alfa Laval’s latest patented design, the CurveFlow, is for asymmetrical ports and features a new fluid distribution pattern that Crozier says lowers pressure drop, or increases efficiency with the same pressure drop. “We have also introduced a new method to secure gaskets to plates without glue being required,” he says. The company continues to develop new patterns used on various plates to increase efficiency vs. pressure drop, reduction of material thickness while maintaining pressure capabilities, applying new construction materials for plates and gaskets, as well as special unit types for specific applications. “Unlike the traditional shell-and-tube ‘one design type fits all,’ the Alfa Laval frames have been drastically improved,” Crozier says, “with better ways to open and close the units, studded ports that are in-place rather than nozzles, and bearing boxes that reduce resistance during tightening of bolts.” McGinnis says in finned-tube technology, Kelvion continues to produce advancements in dry-air cooling in both fin- and tube-side augmentation, fan efficiency increases, and reduced noise footprint. “The future of dry-air-cooled heat exchange is small, incremental improvements that benefit everyone involved,” McGinnis says. “The future of heat exchange is using greater thermal efficiencies through more efficient use of pressure drop, flow distribution, and effective use of proper channel hydraulic diameters based upon application suitability.” http://biomassmagazine.com/articles/13799/the-ins-and-outs-of-heat-exchangers

Two buyout groups bid for GEA heat exchangers unit - sources

(Reuters) - Two buyout groups have made final offers for the heat exchangers division of German industrial machinery and process engineering group GEA , one of which could be picked for exclusive talks within days, three people familiar with the matter said.
EQT, which is working with industrial services group Bilfinger, and private equity investor Triton handed in bids valuing the unit at about 1.2-1.3 billion euros ($1.65-$1.8 billion) by a Friday deadline, the people said.
"However, the headline price does not give you the complete picture because almost a third of the unit's roughly 1.5 billion euros in sales is project-business, which comes with guarantees," one of the people said.
Some of the risk from these guarantees may wind up staying with the seller, potentially inflating the sales price, he added.
GEA, EQT, Bilfinger and Triton all declined to comment.
The heat exchangers division, GEA's second-largest business by revenue but last year defined as non-core, makes equipment for a wide range of applications from air conditioning to cooling towers.
In the consortium comprising Bilfinger and EQT, the industrial services group is interested in acquiring the cooling towers activities, while the buyout group would take the rest.
Triton acquired the heat exchanger business of Alstom earlier this week. But sources familiar with the transaction said the GEA and Alstom units are so different that few benefits would be gained by merging them. ($1 = 0.7263 euros) (Reporting by Arno Schuetze; Editing by Hugh Lawson)

EJ Bowman has extended its range of exhaust gas heat exchangers with its new type 15 unit which is capable of recovering waste energy from engines rated up to 1MW. The type 15 heat exchanger means Bowman can now cater for larger scale power generat ion applications.

First unveiled at the Hannover Fair 2013 the Bowman type 15 heat exchanger generated a huge level of interest, reports the manufacturer.

Designed specifically to address market demands for a high efficiency unit for engines up to 1MW typical power, the type 15 is capable of recovering around 600kW of waste heat through the engine’s exhaust stream at an exhaust gas mass flow rate of 70kg/min.

The unit is perfect for larger independent genset applications, where high levels of waste heat that would otherwise be lost to the atmosphere can be recovered and used to provide either hot water or heat thermal oil for ORC systems at no extra cost in terms of fuel usage.

Commenting on the launch of the unit, Kevin Howell of Bowman, told UKPN: “The launch of the type 15 heat exchanger is a significant step toward into larger scale power gen applications for Bowman. It also gives genset manufacturers the opportunity to offer their customers CHP solutions that combine exceptional efficiency with a competitive price.”

As well as for heat recover, these units can also be used to reduce the exhaust temperature in engines operating in hazardous environments where for safety reasons it is necessary to reduce the temperature of the exhaust gases.

In common with all standard Bowman Exhaust Gas Heat Exchangers, the new type 15 unit is suitable for use with engines powered by Biogas, Diesel Gases and Natural Gases.

Bowman Exhaust Gas Exchangers are manufactured to a standard range of sizes, they are competitively priced and offered on a quick delivery to meet clients’ build schedules.

Bowman can also now offer several exhaust gas heat exchangers with right-angled end covers, which are fitted with a removable plate on each end, allowing easy access to the heat exchanger tubes for cleaning and maintenance without the need to drain the system.

When Bowman exhaust gas heat exchangers are used in conjunction with other Bowman units such as: Header Tank Heat Exchangers, Charge Air Coolers and Bowman Oil Coolers, it is possible to reclaim over 90% of lost heat from the engine.

Bowman heat exchangers are tested to the limit and proven in the most demanding applications, the world over – including the British Antarctic Survey’s (BAS) new research station, Halley VI (http://www.bas.ac.uk/). In winter, temperatures on the Brunt Ice Shelf plunge to −50°C and snow falls for half the year.

Bowman units are critical to the combined heat and power system (CHP) which supplies energy for space heating, hot water, lighting, ventilation and electrical power.

Without this CHP system, the people on the resident BAS team who live and work at the base could not survive.

The units met the demands of this unique artesian water supply, a variety of pool sizes, heating methods and the massive fluctuation in outside air temperatures – from below freezing in winter up to 40°C in summer.

Bowman heat exchangers are also central to three CHP power plant units at a Finnish eco residential project.

The units are fitted to Sisu Gensets for recovering waste heat from the exhaust and jacket water systems. The power plant supplies heat and power to 10 houses.

EJ Bowman is a worldwide, ISO9001:2008 certified OEM manufacturer of Heat Exchangers and Oil Coolers for industrial and commercial applications.

Bowman occupies a purpose-built factory which is ideally situated centrally in the heart of the UK, from where it directly exports over 70% of its production worldwide.

Unison Announces Surface Cooler Heat Exchanger Enhancements

LE BOURGET, France, Jun 17, 2013 (BUSINESS WIRE) -- Unison Industries today announced enhancements to their conformal Integrated Fin Technology(TM) surface coolers. These unique heat exchangers are in service on the GE powered Boeing 787 aircraft, and they were selected for Leap-1B and the new GE Passport engine. They will save customers thousands of dollars annually in specific fuel consumption (SFC) since they are lower weight and produce less drag. An additional benefit to the new design is flexibility in cooler shape, since the heat exchangers are no longer limited to "box" configurations. The Unison surface coolers lend themselves to whatever shape best suits the engine flow contours on which they will be installed. Unison's advanced heat exchanger technology is patented and patent pending.

Mike Grunza, president of Unison Industries, said, "We have been developing this innovative technology for several years and we believe we have only scratched the surface of what is possible with our Integrated Fin Technology(TM). The continuous evolution of the design confirms that Unison is committed to advancing the technology."

Unison surface coolers offer "always on" integrated oil de-congealing passages in their base. With this enhancement anytime oil is flowing through the system it is providing the warmth necessary to de-congeal oil in the core of the surface cooler after the system has been exposed to very cold temperatures for an extended time. These integrated oil de-congealing passageways are highly desirable features since the surface coolers tend to be long in circumferential length.

A second feature focuses on combining two or more heat-exchangers into a single assembly. This will be useful when both the generator cooler and engine lube oil cooler are located in close proximity. Since the manufacturing process accommodates such an arrangement, these features can be incorporated into Unison's conformal Integrated Fin Technology(TM) surface coolers.

Grunza added, "Engines already in service are also excellent candidates for Unison's surface cooler technology, and retrofitting to the Unison heat exchanger is a great opportunity to reduce weight and drag, reducing operating costs."

Unison Industries, LLC, is a leader in the design, manufacture and integration of electrical and mechanical components and systems for aircraft engines and airframes. Unison serves both original equipment manufacturers and aftermarket customers in commercial, military and general aviation markets. Unison's headquarters are in Cincinnati, OH, and it employs more than 4,000 people in fifteen manufacturing facilities and logistics centers worldwide.

Xylem Lowara Launches New Range of Advanced Heat Exchangers

Xylem Lowara UK has launched a new range of advanced brazed and gasketed frame plate heat exchangers specifically designed for domestic, commercial and industrial applications.

The new heat exchange plates combine a chevron-style heat transfer between the frame and pressure plates for superior efficiency. The heat transfer plates have holes at the four corners that form a header, which distributes the fluids to the opposite sides of each plate when the plates align. This results in the fluid being confined to the heat transfer surface of the plate.

The new range, which is capable of dealing with temperatures ranging from -350C to 1700C, has a maximum flowrate of 1365 l/sec and can withstand pressures of up to 20 bar as standard. The modular design of the heat exchangers means the inlet and outlet connections are on the same plane, keeping installation and maintenance simple.

Gary Wilde, Business Development and Marketing Manager for Xylem Lowara UK, said: “The new heat exchangers have been designed to offer not only effective re-cycling of waste heat, but also a system which is simple to install and maintain.

“The versatility of the heat exchangers means they are ideal for use in an extensive range of domestic, industrial and commercial applications across the HVAC, food and beverage industry, marine and automotive sectors to name just a few.”

With a studded connection which comes in five different options, the heat exchangers require no welding when being assembled or any special tools to tighten the plate pack. The opening and closing of the unit requires no disconnection allowing easy expansion of the piping and the overall unit providing easy access to intricate components.

Lasers Can Effectively Weld Heat Exchangers

Can lasers perform welds precisely and reliably in the midst of thundering machinery? The prototype of a new laser welder developed by an international team of researchers has now withstood the worst.

At INTEGASA and ENSA, two companies in Spain that produce heat exchangers for heavy industry, the prototype proved itself precise and reliable under the difficult conditions of routine daily use.
“Manufacturers of heat exchangers were skeptical of laser anything until now,” confirms Patrick Herwig from the Fraunhofer Institute for Material and Beam Technology IWS in Dresden. TIG-welding guns have traditionally been employed in assembly operations for welding thousands of tubes to the perforated tube sheets. This process, which is based on arc-welding technology, is very time-intensive however. The gun must be manually inserted into every hole and removed again after welding. As a result, the fabrication process is tedious, prolonged, and expensive. European manufacturers can hardly hold their ground today against competition from countries with low labor costs. Materials researchers, software specialists, production engineers and numerous users joined forces in the EU ORBITAL Project to jointly search for a cost-effective alternative. And found one.
Engineering that meets the most demanding requirements Instead of conventional TIG-welding guns, a laser does the job – tube sheets and tubes are welded to one another rapidly, precisely and accurately. In seconds, the tube is circumferentially welded in place and the robotic arm transporting the welding head can move on to the next hole. The welding head is designed so it anchors itself in the holes and is seated there so firmly than not even vibrations of the shop floor can disrupt the welding process. Precise guidance of the optical beam is handled by software-controlled mirrors that continuously direct it to the right location. Engineers and users from Italy, Spain, France, and Germany have been fine-tuning the process for two years. “The prototype we are exhibiting now at LASER 2013 facilitates the production of heat exchangers, and not just through its speed, but through its flexibility as well. It can even melt materials together that were considered difficult to weld until now,” according to Herwig, who was responsible for designing and testing the welding head during the EU project.
It is exactly these exotic combinations of materials that are needed by manufacturers of heat exchangers. They have to withstand extreme conditions in actual use. Heat exchangers are used in the chemical industry, ship engines, and power plants to remove heat from high-temperature, aggressive solutions of liquids. The tubing these liquids are passed through must therefore be corrosion-resistant. However, the liquid in the tank outside the tubing that absorbs the heat is chemically inert. Cost-effective materials can be employed here. Where tank and tubing meet, differing materials must be joined. “Traditional welding techniques hit their limits here, whereas the job can be handled with the laser,” says Herwig. The researchers are confident that laser welding can be implemented so effectively in production that European companies remain competitive internationally.

Emerson introduces pre-engineered Heat Exchanger Monitoring Solution

Emerson Process Management has announced the release of an integrated Heat Exchanger Monitoring Solution.

Emerson Process Management has announced the release of an integrated Heat Exchanger Monitoring Solution. The solution is part of Emerson’s new suite of Essential Asset Monitoring applications. The pre-engineered heat exchanger solution embeds process and exchanger best practices into software using existing wired and new wireless instrument applications for cost-effective automated 24/7 monitoring enabling operations improvements and reduced energy costs.

Emerson’s Heat Exchanger Monitoring Solution allows maintenance personnel to schedule optimal time to clean to sustain optimal heat transfer. As a result, facilities can reduce energy and capacity loss due to fouling by up to 10 percent. For a 250,000-barrel-per-day refinery, that could mean a savings of as much as $3.5 million or more annually across all process units.

The environmental footprint is lessened by avoiding additional emissions from heater operation because of improved heat recovery in the process. And safety is improved as wireless data transfer reduces hazardous information-gathering trips to the field amongst exchangers that can be difficult to access, stacked, and filled with hot flammable fluids

"Typical world-class process facilities use hundreds of heat exchangers, which foul over time resulting in missed operating targets," commented Pete Sharpe, Emerson’s director of applications development. "Fouling typically occurs slowly but can be accelerated by inlet stream impurities or incompatible crude blends."
"Energy costs rise when fouling forces downstream process heaters to supply more energy

because of

heat transfer degradation in pre-heat exchangers," continued Sharpe. "Increased demand on downstream fired heaters can also diminish throughput as operating temperature limits are reached, and can increase emissions and potential fines. Avoiding these issues requires an effective cleaning program that enhances operations, and eliminates costs and time lost due to unnecessary schedule-driven cleaning or manual exchanger surveys."

The Heat Exchanger Monitoring Solution is scalable. Users simply choose the number and type of monitoring applications and instruments that are needed for their facility. Dynamic temperature and pressure measurements are trended, historized, and analyzed, delivering alerts of accelerated fouling and optimal time to clean.  Heat transfer, exchanger heat-transfer coefficient, fouling factors and cost of degradation can be calculated. Operations personnel can get valuable insight into operations that can be adversely affected by exchanger fouling.

The monitoring instruments are easily installed and commissioned to form a wireless field network for automatic online measurements. The Heat Exchanger Monitoring Solution uses AMS Suite operator graphics and maintenance screens to communicate continuous online diagnostics and application data to user host systems, control systems, and historians.

"The new automated monitoring solutions reduce costs through pre-engineering savings and wireless efficiency," said Sharpe. "Whereas wired continuous monitoring is traditionally afforded for only the most expensive and critical heat exchangers, the lower costs of Essential Asset Monitoring Solutions enable expanded asset oversight."

The Effects of Heat Exchangers on Oil

Heat exchangers are often used on equipment to cool the system, but what effect does this have on the oil and on equipment life?
Many heat exchangers are installed at the factory depending on the size or criticality of the machine. For these types of equipment, the maintenance staff must keep the heat exchanger operating within a certain parameter. If these parameters are exceeded, the equipment will eventually go down, usually because of a safety feature that trips the equipment due to a high temperature.
If you have had the opportunity to attend one of Noria’s Fundamentals of Machinery Lubrication classes, you are aware of the importance of keeping lubricants clean, cool and dry, and equipment balanced, aligned and well-oiled. These are some of the proactive practices that help ensure your equipment has the best opportunity to stay as healthy as possible. Heat exchangers can be utilized as part of one of these proactive practices — keeping the lubricant cool.
Heat is one of the four pro-oxidants. The others are air, water and metal catalysts. These pro-oxidants lead to the formation of acids, varnish, sludge and high viscosity, which normally result from oxidation. Oxidation is the permanent degradation of a lubricant by chemical reactions involving oxygen. As oxidation progresses, long-chain molecules are produced, which promotes the formation of sludge, tar, varnish and acids.
Individuals who review oil analysis reports typically look at an increase in viscosity and acid number to determine the health of the lubricant. While this is important, it is critical to change the lubricant before the critical limit is exceeded. Don’t forget that the health of your lubricant is your insurance for maintaining healthy equipment. Whenever you neglect your lubricants, you are also neglecting your equipment and allowing sludge, tar and varnish to become contaminants that can damage bearings, servo valves, etc., and cause equipment failure. As oxidation increases, so do acids, which results in corrosion of internal components.

Heat exchangers can play an important role in reducing heat within a system. Regardless of the type of heat exchanger used, it should be operated within its limits to ensure that the lubricant is kept cool. Refer to the manufacturer of the heat exchanger to make sure you are within the appropriate limits.
You should also keep in mind that for every 10 degrees C (18 degrees F) over the operating temperature, oil life is cut in half (Arrhenius rate rule). This means that if you have high temperatures and a heat exchanger that is not set up properly, it will produce more rapid oxidation.
In the reliability world, it is understood that oil will need to be changed more frequently in a machine that is running hot than in a cooler machine, but you can also apply the Arrhenius rate rule to your car. For instance, the hotter the oil in your vehicle, the more frequently you will need to change the oil.
However, do not think that only heat leads to oxidation. You still must deal with air, water, metal catalysts and all of the other contaminants that can enter into the lubricant.
So look a little more carefully at the machines in your plant that are currently running hot. They may be good candidates for a heat exchanger. In addition, if you can cool the lubricant by 10 degrees C (18 degrees F) of its operating temperature, you can double the oil’s life. Remember, a cool lubricant will increase the health of the lubricant along with the reliability of the equipment.
