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 a 316 stainless steel shell and tubes are the most corrosion resistant.
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.

High-Pressure Heat Exchangers
With more than three times the pressure rating of standard heat exchangers, these are often used for high-pressure condensing, evaporating, heating, and cooling. Also known as shell and tube heat exchangers, they transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes. Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference. Shell and tubes are 316 stainless steel for excellent corrosion resistance.

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.

Cold Plates
Connect these plates to cold liquid lines in process chillers and liquid-to-air cooling systems to cool equipment through direct contact. All have tubes that pass through a thermally conductive aluminum plate. Drill or tap the plate for mounting.
Cold plates with 316 stainless steel tubes can stand up to corrosive liquid and deionized water. Those with fittings let you connect to your system without having to weld or attach your own fittings.
