Heat exchanger contract is a joint effort

Two UK companies recently combined forces to provide a solution for the oil and gas industry that they belive could not have been achieved anywhere else in the world.

Heatric of Poole in Dorset designs and manufactures compact diffusion-bonded heat exchangers for offshore and onshore gas applications. As part of a £multimillion process order in the Middle East, Heatric constructed the exchanger cores from 6% molybdenum stainless steel for corrosion resistance to a sour gas working environment.
Redditch-based Harper and Simmons, a specialist toolmaking company with one of the most extensive large-capacity wire eroding facilities in the world, provided the chipless machining solution that Heatric required to guarantee clear small fluid flow channels, vital to the compact core design.
Heatric believes it is the only company in the world capable of diffusion bonding stainless steel on such a large scale and that Harper and Simmons was the only supplier with sufficient capacity in size and quantity of wire cutting machinery to be able to meet the lead times and requirements of this Heatric project.
Almost 10,000 hours of cutting time were required for the project; 166,000mm being cut at a cutting speed of 0.3mm per minute due to the extreme thickness of the materials. Harper and Simmons’ facilities include what it believes to be the world’s largest number of super-size Hitachi bridge-type wire eroders under one roof; the only machines capable of accommodating the capacity and the weight of the Heatric components. In addition, heavy lifting craneage to transfer the non-magnetic material from machine to machine along with full toolroom back-up provided a turnkey solution for Heatric unavailable anywhere else in the UK or overseas.
“The innovative design of Heatrics’ heat exchange core and the wire cutting capacity of Harper and Simmons in supply partnership ensured the quality and delivery required for the end user,” says Michael Yorke, operations manager at Heatric. Robert Simmons, managing director of Harper and Simmons

Robert Simmons, managing director of Harper and Simmons adds: “Conventional cutting forces produced by a milling operation would have been totally unsuitable for this particular job because of burnishing the flow channels. Wire eroding, on the other hand, produces a super precision slice to both ends of the heat exchanger leaving a completely clean core. At one point, most of our machines were cutting 24 hours a day, seven days a week to meet the needs of this one project. If there’s any doubt that British industry is dead, then here’s a great example to prove that is absolutely not the case.”
Harper and Simmons’ state-of-the-art water jetting facilities, which include one of the few three-axis cutters in the UK, are also meeting the challenging cutting demands of Heatric’s exotic high-tech alloys.

Dana develops new heat exchanger for electric vehicles

Dana Holding, a US-based supplier of axle, driveshaft and thermal products for vehicle manufacturers, has developed Long heat exchanger designed to extend battery life in hybrid and electric vehicles.

The company said the heat exchanger has recently debuted on Tesla Motors's 2010 all-electric Roadster Sport car. The heat-exchange technology cools the Roadster's battery by transferring heat generated within the battery to the vehicle's climate-control system.
In addition, a temperature sensor mount provides continuous feedback to the climate-control system. The interface reportedly helps to maintain the battery's ideal temperature during operation, thus helping to extend battery life.
Dana engineers have constructed the heat exchanger using a patented aluminum brazing process, ensuring cleanliness of both the climate control and battery coolant fluids. Dana is manufacturing the heat exchanger at its advanced engineering center at Oakville in Ontario, Canada.
Jim Sweetnam, president and CEO of Dana, said: "Dana is committed to providing our best-in-class engineering and manufacturing expertise to electric-vehicle manufacturers such as Tesla Motors. Our advanced battery technology solutions will help drive our growth in this exciting market segment."

Emerson ships rear door heat exchanger

Emerson is shpping the Liebert XDR, a rear-door heat exchanger that removes heat from IT racks before it ever enters the data center.

The Liebert XDR microchannel heat exchangers are mounted in a moveable door, which is fixed to a frame attached to the rear of the rack. It relies on server fans for hot air movement across a cooling coil, utilizing a pumped refrigerant that is 700 percent more efficient at removing heat than water. The pumped refrigerant also eliminates any danger of equipment damage from water leakage. Air exits the Liebert XDR at approximately the same temperature as the air entering the front of the rack, neutralizing the heat created by the servers.

 “Because the Liebert XDR cools the air exiting the rack before it enters the room, there is no need for fans to move heat across the room to wall or floor-mounted cooling systems,” said Bob Blough, director of product marketing, Liebert precision cooling, Emerson Network Power.

“Eliminating the cooling fans makes it possible for businesses to realize energy savings of 35 to 48 percent compared to perimeter cooling – let alone the capital cost savings from not needing to expand or build a new facility.”

Feature include ability to cool up to 20 kW of rack load, even in a hot aisle/cold aisle configuration. The door opens more than 100 degrees and allows for side-by-side placement of racks in open and closed positions.

A flexible connection of hard-piped, pumped-refrigerant lines through the rack door’s hinge pivot points, which enables it to be robust and leak-free through more than one million repeated door openings and extended periods of time with no movement. These overhead piping connections are completely static – no moving components will interfere with opening or closing the door.

Pumped refrigerant from a Liebert XDP or Liebert XDC enters the fixed frame and passes through an innovative hinge to the door.

The product has been shipping for the last year as the Sun Microsystems SCD5600.
Jack Pouchet of Emerson will talking about the firm's St. Louis data center on Day 1 at DatacenterDynamics London and be taking part in a panel discussion on renewable energy on Day 2. Details on the link below.

Heat exchangers exhibit rapid response to change

The Compheat range of heat exchangers is ideal for small plant rooms and various applications including heat recovery, heating, cooling, pumping and filtration.
ARI-Armaturen UK exhibited its ARI Compheat heat exchange unit that provides accurate heat control at Foodex 2006.
This trusted product within the ARI range offers a compact solution for heat transfer requirements, for the generation of both domestic hot water and LTHW (spell out) from either steam or MTHW (spell out).
Occupying less than 1m2, with low capital cost and low maintenance requirements the Compheat range is ideal for small plant rooms and various applications including heat recovery, heating, cooling, pumping and filtration.
The ARI Compheat is a reliable, efficient and low cost system that offers accurate electric or pneumatic control.
Because control is achieved by progressively bypassing secondary water flow away from the heat exchanger, the Compheat has a particularly rapid response to changes in load.
ARI Compheat benefits from a selection of standard equipment that differentiates itself from competitors and ensures high performance.
A full isolation package of high quality bellows sealed stop valves for the primary circuit, and circuit lined butterfly valves for the second circuit, comes as standard, as does the "clean in place" connectors to simplify the maintenance process.
Safety is also of utmost importance, the Compheat comes complete with a self-acting high temperature cutout to protect the unit from over heating and because the primary circuit is permanently charged there is no risk of water standing within the unit at low temperature, removing entirely the risk of legionella bacteria build up.
The packaged heat exchange units are also available with extended options that include pumped condensate systems, pressure reduction and steam conditioning.
In addition, a completely customised system can be provided to match specific requirements.

New device replaces NH3 heat exchangers

Steam traps were invented in 1835 and have been widely used ever since. They separate liquid from steam and reduce water hammering and other problems in steam systems.

Now, Lauren Kiest, who invented the Equaply NH3 system 10 years ago, has developed a reverse steam trap to take vapor out of anhydrous ammonia (NH3) as it flows from nurse tanks to manifolds on application equipment. You can also think of it as an upside-down steam trap.

Vapor is the 800-pound gorilla when it comes to handling NH3. It's virtually impossible to measure and meter a combination of liquid and vapor. Consequently, it's a challenge to apply the desired rate, and some outlets on many applicators apply much more nitrogen (N) than others.


Kiest says his invention, called the Liquimatic Vapor Separator, eliminates the need for heat exchangers. "The only purpose for the heat exchanger in an anhydrous ammonia system is to condense ammonia vapor back to a liquid," he says.


0813nitrogen03.jpg

According to Kiest, the stream of NH3 entering the Liquimatic is about 45% gas and 55% liquid, by volume. NH3 is a liquid in nurse tanks, but vapor is formed by friction as it flows through hoses and pipes after leaving the tank.

In addition to eliminating most of the vapor, Kiest says the Liquimatic also has more capacity than heat exchangers. For example, he says the two heat exchangers on his company's original Equaply system can supply about 60 gallons per minute, whereas the Liquimatic system can handle rates in excess of 80 gallons.

"That's enough capacity for a 60-foot applicator going 12 mph to apply 250 pounds of anhydrous ammonia per acre," he says. (That's just over 200 pounds of N).


After 5 years of development, Kiest and his company -- aNH3 Company -- are now starting to sell the new devices, which are patented (U.S. 7,096,802).

The Liquimatic is surprisingly simple. A weir, or metal dam, in the canister diverts the incoming mix of liquid and vapor upward. The liquid flows up and over the dam. Meanwhile, the vapor rises to the top of the canister (see illustration above).

When the amount of vapor reaches a certain point, a float inside the canister trips a switch that opens a solenoid valve and allows the vapor to escape. A small tube attached to that valve carries the vapor to a knife or opener. The Liquimatic system actually has two identical solenoid valves. One is basically a backup for the other one. As the vapor or gas is bled off, the liquid rises, turning off the switch and closing the solenoid valve.

The liquid in the canister or tower has a small amount of head pressure. "The head pressure assures that the liquid leaving the bottom of the tower is below saturation pressure and not boiling," Kiest explains. "Therefore, a flowmeter after the tower senses pure liquid and reads correctly. Similarly, a pump after the tower does not have vapor to cause cavitation."

Applicators applying low rates may not need a pump in the system. But Kiest expects that most customers will order a system with a pump and use it at least part of the time.

"If you are running when it is really cold or if you have a really high rate of flow, you are probably going to need a pump," he says.

The pump is a Hypro hydraulic pump with special seals for NH3. Two nurse tanks with big hoses will be needed to apply high rates. The list price for a Liquimatic without a pump or any other component is $7,900.

Prices for a complete system range from about $10,000 to $25,000 depending on the size of the applicator and complexity of the system. The high end of the range is for an applicator with 24 outlets and swath control valves (but not a controller).

When a complete system is purchased, it comes assembled and mounted on a base plate that can be attached to the applicator.

"I expect the Liquimatic to replace the original Equaply system with heat exchangers this fall," says Kiest.
