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 3CAV is primarily used between rooms with extreme temperature differences and very high traffic.

The frost elimination cycle is similar to the Model DCAV but the additional vestibule improves efficiency as well as increases the model's temperature range applicability. 

The Model 3CAV automatically adjusts as conditions change to optimize performance and reduce energy consumption.

With the use of HCR sensors and software, Model 3CAV can be integrated into a facility's refrigeration control and monitoring system.  This allows both remote monitoring and remote adjusting of the HCR equipment.

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

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 basic NPAC model is made to counteract the one-way flow-through forces caused by negative building pressure or by wind effects.

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.
