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

Patent Pending

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.

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.

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.

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.

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.
