12-metre monotube heat exchangers

Heat transfer solutions provider Teralba Industries has recently expanded its range of Dimpleflo Monotube Heat Exchangers, to include a12-metre long configuration.

The new line-up includes a 12-metre Dimpleflo Monotube complete Colourbond-clad insulation, at one of Australia's largest wineries, located in Griffith NSW. To provide the most cost-effective solution with restricted footprint size, these units were produced with 12m long, unique Dimpled stainless steel tubing, says Teralba.

The new 12-metre long Dimpleflo reduces the number of welds, stainless steel fittings and 180°elbows, by over 40 per cent, when compared to traditional 6-metre heat exchangers, according to the company. This provides large processors across a broad range of industries, with significant cost savings, says Teralba.

A further feature is the reduction in pressure loss through the Dimpleflo due to the reduced number of bends. This in turn reduces initial capital costs, due to smaller product and service fluid pumps being required, as well as reduction in power consumption.

Other features of the new 12 metre Dimpleflo Heat Exchangers include:
- Designed and made in Australia;
- Flexibility in heat transfer design to meet specific dimensional or functional requirements;
- Hygienic self-draining design that is easy to clean;
- Dimple profile to promote a highly turbulent flow and maximise heat transfer coefficients;
- Can be constructed using 2205 duplex alloys and titanium for increased corrosion resistance.

New Copper-Brass Heat-Exchangers Excel in Generator Set, Locomotive, Off-Road and Military Applications, Says International Copper Association

NEW YORK - (Business Wire) A new wave of interest has materialized for CuproBraze® technology, especially for stationary generators, locomotives, off-road equipment and government and military systems, says the International Copper Association.

The chief reason for the popularity of CuproBraze technology is that it allows for the use of brazed serpentine-fins (often of the square-wave type) in brazed copper-brass heat exchanger designs. In large heat-exchanger applications, CuproBraze technology faces off against at least three competitive core technologies: soldered copper/brass plate fin; soldered copper/brass serpentine fin; and brazed aluminum serpentine fin. In the face of this competition, CuproBraze technology is emerging as the first choice in such applications.

Large CuproBraze heat exchangers with serpentine fins have important advantages over competitive designs. They are less expensive to manufacture than soldered plate-fin designs yet more durable than soldered serpentine-fin designs (because of much stronger joints). Compared to brazed aluminum serpentine-fin designs, they also are more rugged and they offer greater cooling efficiency because thinner materials allow for more air to pass through. Finally, square-wave type serpentine fins are not easily clogged and can be cleaned with pressurized water, allowing the thermal performance to be maintained during operation.

The new CuproBraze heat exchangers are rugged enough for the harsh operating environments of these applications. Fully assembled heat exchangers made from CuproBraze alloys, soldered copper-brass and brazed aluminum heat exchangers were subjected to at least four different corrosion tests: 1) Road environment pollutant, 2) Salt spray, 3) Sea water acetic acid, and 4) Marine air corrosion. These test results confirmed that CuproBraze resists corrosion much better than soldered copper-brass and is very competitive with brazed aluminum. Information about these tests can be found in the "CuproBraze Brazing Handbook,” which can be downloaded free-of-charge at www.cuprobraze.com.

“In terms of durability, CuproBraze has proven itself in applications such as locomotives, generator sets and off-road equipment as well as in military environments,” says Nigel Cotton, Automotive Manager for the International Copper Association. “Heat exchanger manufacturers are bracing themselves for a second wave of demand for CuproBraze products.”

Heat Exchangers for Outdoor Corn Boilers

A heat exchanger is a device designed to efficiently transfer the heat from one medium to another. In the case of an outdoor corn boiler, these media would be air and water.

A typical domestic setup would include a water-to-water heat exchanger for hot water and a water-to-air heat exchanger for forced air home heat. Water-to-water heat exchangers are also used to heat hot tubs, swimming pools and the water for radiant baseboard or radiant in floor
heating systems.

Water-to-Water Heat Exchangers

The three most common types of water-to-water heat exchangers used with outdoor
corn boilers are: Sidearm, Shell and Tube, and Brazed Plate. What differentiates these heat exchangers, besides the cost, is the way they're designed to transfer heat from one medium to another and the method used to create turbulence.

A key component in the efficient transfer of heat between liquids is turbulence. The
more turbulent the flow of water through a heat exchanger, the more efficiently heat
is transferred.

Sidearm Heat Exchanger

The sidearm heat exchanger is a popular and inexpensive choice for heating
domestic hot water. It incorporates a pipe within a pipe design where the
water in the inner pipe (your hot water) is heated by hot water from the
boiler circulating through the outside pipe.

Turbulence is created by scrolling on the outer surface of the inside pipe.

This straightforward design prevents clogging by sediment and resists
scaling. One drawback of the sidearm heat exchanger is reported slow
recovery under heavy use. Cost: $130-$150.

Shell and Tube Heat Exchanger

Shell and tube heat exchangers are available in dozens of tube configurations and
sizes ranging from a few feet long to 50 feet or more for power plant steam
generation.

A variation on the shell and tube design is shell and coil where a helical (spiralling) coil
replaces the tubes.

No matter what the design or application, the basic principle is the same. The water to
be heated flows through tubes, and the heated boiler water, encased by the shell,
flows around the tubes.

Turbulence is created by the baffles holding the tubes together in what is called a tube bundle.

Shell and tube heat exchangers for non-chlorinated water
applications, such as domestic hot water and hydronic
heating, are usually constructed with a brass shell and
copper tubes.

For swimming pools and spas the shell should be PVC or stainless steel with stainless
steel tubes. 316L grade stainless steel is commonly used for this application.

Cost: $200-$600 depending on copper or stainless construction and the overall size based on the volume of water to be heated.

Brazed Plate Heat Exchanger

The brazed plate heat exchanger combines compact size with a highly efficient design to produce a device for heat transfer that is up to six times smaller than a shell and tube heat exchanger of similar capacity.

The key to this efficiency lies in their unique construction. Corrugated stainless
steel plates are brazed together (eliminates gaskets) with every
second plate turned 180 degrees. This design creates two highly
turbulent fluid channels that flow in opposite directions (counter flow)
over a massive surface area.

Cost: $100-$500 depending on capacity.
