Heat Exchangers
Also known as shell and tube heat exchangers, these transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes. They’re commonly used in refrigeration and engine cooling systems. Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference.
Heat exchangers with baffled tubes direct liquid to make four passes through the tubes for more efficient heat transfer than other heat exchangers.
ASME BPVC VIII.1 heat exchangers meet the ASME Boiler and Pressure Vessel Code (BPVC) for construction of pressure vessels.

Heat Exchangers for Sampling
Surface
Area
Surface
Area
Often used to monitor boiler water quality without shutting down the system, these heat exchangers cool hot liquid samples to safe temperatures for testing. Sample liquid flows through the tubes, and cold water from an external water supply flows around the tubes to cool the liquid in the tubes. Cooled sample water then flows out of the heat exchanger for analysis.
304 stainless steel tubes are more corrosion resistant than copper tubes.
316 stainless steel tubes have the best corrosion resistance.
Heat exchangers with 1.3 or 1.64 sq. ft. surface area are often used for sampling liquid from a boiler. Heat exchangers with 3.8 sq. ft. surface area are good for sampling steam from a boiler or for continuously cooling sample water.

Enclosure-Cooling Heat Exchangers
Cool the air in your enclosure to protect electronic components from excessive heat. These heat exchangers absorb heat in the enclosure, then use cooler air outside the enclosure to draw the heat away, lowering the temperature inside. Unlike a fan, they seal out outside air, so dust, moisture, and other contaminants can't get in. Because they use ambient air to cool the enclosure, heat exchangers use less energy and are less likely to cause condensation than air conditioners.
Heat exchangers that meet NEMA 12 and IP54 seal out dust, dirt, and splashing water and oil. Made of steel, these enclosures are powder coated, so they won’t rust in damp environments, but they’re not watertight enough to use outdoors.
NEMA 4- and IP56-rated heat exchangers are designed to withstand rain, snow, and washdowns. They’re made of powder-coated steel.
Heat exchangers rated NEMA 4X and IP56 are made of stainless steel to resist corrosion in the harshest environments. They stand up to weather, washdowns, and corrosive chemicals.
All of these heat exchangers meet American and Canadian safety standards. CE marked heat exchangers also meet European safety standards.
