The Model CAC Air Curtain is for applications where temperatures and humidity exceed the limits of our Model AC. A heater unit is added to condition the air as it mixes inside the vestibule.

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

With the use of HCR sensors and software, Model CAC 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.

The Model ASSD is a swift opening and closing motorized strip-door.  Strip-door operation is easily adjusted to suit traffic speed. 

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

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.

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.

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.
