A conditioned air vestibule that uses a push-to-open versus a motorized opening.

Patent Pending

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.

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.

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.

Miniature/small version of CAC for conveyors.

The Model ECAV consists of two fast-acting strip doors that create a vestibule for conditioning air and an electrically or hot-gas heated anti-frost air-conditioning (AFC) section with automatic temperature control.

The ECAV is designed for medium to light-traffic freezers and high humidity situations.
