A small conditioned air vestibule with touch opening capability.

By combining an air door with your currently installed door, you are assuring an efficient air block when your hard door is open, reducing cold air loss and decreasing the problems associated with high-traffic openings, such as ice and safety concerns.

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.

The Model DCAV uses two recirculatory air curtains, creating an air vestibule between the two air streams where the air is captured and treated to a non-frost, non-fog state. 

The Model DCAV automatically adjusts as conditions change to optimize performance and reduce energy consumption.

With the use of HCR sensors and software, Model DCAV can be integrated into a facility's refrigeration control and monitoring system.  This allows not only remote monitoring but remote adjusting of the HCR equipment.

Model AC is HCR's basic unit -- Horizontal, Curvilinear, and Recirculatory. Its air stream produces counter-flow forces equal and opposite to the two-way flow-through forces caused by air temperature differences.

Achieve the next level of efficiency by adding an HCR Model AC or CAC to your existing door. Perfect for high-traffic doorways where ice and infiltration are a challenge, an HCR Air Door provides another layer of protection to assure that the opening remains accessible for workflow, yet closed for costly air infiltration and energy efficiency.
