The Model RCAV is a short, conditioned-air vestibule for freezer to outer room conditions that span large temperature differentials up to 100 degrees with average doorway traffic and limited floor space around the door. It significantly reduces refrigeration load while preventing frost, ice and wetness at the doorway. It consists of two high-speed rollup doors, and a heated horizontal, recirculatory air curtain between the doors. It is equipped with a PLC or Solid State automated control to regulate the amount of air and heat required.
