Our heavy duty, most robust heat exchanger for the very high temperature, very dirty exhaust air streams, where a plate heat exchanger just will not work.

PRE-heat, Inc. manufactures a wide variety of industrial, air-to-air, shell & tube heat exchangers.

Our high quality, rugged, shell & tube heat exchangers are used as primary and secondary heat exchangers on all types of fume incineration incinerators, including catalytic, thermal recuperative and thermal regenerative incinerators. They are also used to recover valuable heat energy from industrial furnaces, kilns, ovens and dryers of all types. From food spray dryers to sand and mineral dryers. Our vertical shell and tube heat exchangers are used on incinerators, kilns and dryers where a great deal of particulate maybe intrained in the exhaust air stream and frequent cleaning would be required. Our proprietary, vertical design heat exchangers greatly increase the time between cleanings and greatly decrease the time it take to clean them. High heat exchange efficiencies are maintained throughout the operating cycle. Our proprietary air lock, floating tube expansion system eliminates the destructive, uneven forces caused by uneven tube growth due to partial heat exchanger plugging. This alone greatly increases the life cycle of our heat exchangers.

PRE-heat's ability to use multiple tube patterns, including triangular, rotated triangular, square, and rotated square, along with multiple shell side flow passes and multiple tube side passes, with either full or partial baffles, allow us to design the proper exchanger to meet your performance needs and fit into the space required. Our quality systems can handle air flows from 100 to 100,000 CFM, with air pressures up to 25 psi and temperatures up to 1,800°F.
