24/7 Service


The world leader in re-circulatory air door technology.
HCR Units are custom engineered and designed for each opening. Since 1974, the founders of HCR set out to find a better solution for moving traffic through cooler and freezer doors where temperature differences cause numerous problems. Using a completely fresh engineering approach and the principles of psychrometrics, the refrigeration engineers at HCR developed new technologies that pioneered the re-circulatory air door/vestibule industry.
Today, with more than 45 years of field experience, HCR has proven itself with thousands of successful installations worldwide. HCR doors can be found inside the facilities of the largest, most demanding and cost-conscious grocery and food distribution centres, food processing plants, refrigerated warehouses, and retail grocery stores.
