In 1974, the founders of HCR set out to find a better solution for moving traffic through cooler and freezer doors. Using a completely fresh engineering approach and the principles of psychrometrics, the refrigeration engineers at HCR developed new technologies that poineered the re-circulatory air door industry.

Today, with more than 30 years of field experience, HCR has gone from the drawing board to application, from a basic idea to reality, and has proven itself with thousands of successful installations worldwide, and inside the facilities of the largest, most demanding and cost-conscious grocery and food distribution centers, food processing plants and refrigerated warehouses.
