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.

Chillers and Heat Exchangers Enhance Looped Liquid Electronics Cooling

Advanced Thermal Solutions, Inc., ATS, has introduced a series of portable Chiller Systems and liquid-to-air Heat Exchangers for controlling fluid temperatures in looped liquid cooling systems.

The new chillers allow precise temperature control of the recirculating coolants used for managing heat in electronic equipment. Coolant temperatures are regulated by thermoelectric module or PID control, depending on the model. For fluid baths, an immersion chiller, the ATS-CHILL iM controls fluid temperature via an immersible evaporator.

Each ATS chiller is portable and readily integrates with liquid cooling systems wherever precise fluid temperatures are required. The chillers provide cooling capacity up to 600W for ensuring accurately cold fluids in labs, industrial systems, laser thermal management, and in calibration and characterization studies.

The new ATS liquid-to-air heat exchangers have the industry’s highest density of metal fins. This maximizes heat transfer from liquid to air, allowing the liquid to be cooled to lower temperatures than other exchangers can achieve. All tubes and fins are made of copper and stainless steel to accommodate a wide choice of fluids. Provided with integral fans, the ATS heat exchangers are available in a range of sizes, and heat transfer capacities up to 250W. They can be used in a wide variety of automotive, industrial, HVAC, electronics and medical applications.

Also for use with liquid cooling system, ATS now provides automatic shut-off valves. These battery-operated electronic devices detect water leaks in piping systems. If a leak is detected it automatically closes a valve to prevent water flow and sounds an alarm.

The new liquid chillers, heat exchangers and leak detectors are available direct from ATS or from its global distributors. All units can be ordered online at Qats.com or by calling Advanced Thermal Solutions: 781-769-2800.

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)

New heat exchangers from EJ Bowman

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.
