Heat Exchange Industries is a division of PCC Sterling Ltd.  Formed in 1908, HEI specialized in the design and manufacture of extended surface heat exchangers, providing solutions primarily for the Power generation and distribution industries.

This is HEI’s brand name for a new air-to-air cooler based on heat-pipe technology.

It has sealed tubes containing refrigerant liquid that’s heated in one air stream, causing convection in one stream and cooled in another to create a thermo-syphon effect.
