Heat Exchangers For Steam

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.

316 Stainless Steel Shell—Heat exchangers with a 316 stainless steel shell are the most corrosion resistant.

Baffled Tubes—Heat exchangers with baffled tubes direct liquid to make four passes through the tubes for more efficient heat transfer than other heat exchangers.

316 Stainless Steel Tube—Heat exchangers with 316 stainless steel tubes are the most corrosion resistant.

Heating/Cooling Capacity—Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference.

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.

Heat Exchangers for Sampling

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.
