Custom Gas-to-Liquid Heat Exchangers for Process Cooling and Heat Recovery

At Krueger Engineering and Manufacturing, we build gas-to-liquid heat exchangers that transfer heat between gas streams and liquid media without mixing the two. These units are applied across process cooling, liquid heating, and heat recovery duties where controlled temperature exchange between phases is required. Our focus is on delivering consistent thermal performance while managing pressure drop, flow behavior, and operating conditions specific to each application.

Gas-to-liquid heat exchangers are part of Krueger Engineering’s core heat exchanger capabilities, supported by in-house engineering and manufacturing. We develop each unit using thermal modeling, optimized tube and baffle layouts, and precision machining to match process requirements. Fabrication and testing are handled within our facility to ensure structural integrity and reliable operation in demanding environments such as refining, petrochemical, and gas processing services.
