The high-speed door for cold-storage chambers up to -30º has been designed to compartmentalize areas with atmospheric conditions in which the maximum difference in temperature is 25 ºC (for example, -25 ºC interior 0 ºC exterior) and the maximum atmospheric humidity is 30%. This door has been designed with a 3-layer fabric: 2 PVC + 1 foam. Together with the heated guides system and the motor with heated resistors, it guarantees the correct operation of the door in freezing chambers areas and it reduces frost formation.
