Model NPAC Negative Pressure Air Curtain
The basic NPAC model is made to counteract the one-way flow-through forces caused by negative building pressure or by wind effects.
Hybrid: AC & CAC with Roll-up Doors
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 DCAV Double Conditioned Air Vestibule
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.
The Model CAC Air Curtain
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.
PCAV® Push-Thru Conditioned Air Vestibule
A conditioned air vestibule that uses a push-to-open versus a motorized opening.

AC Air Curtain
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.
