Air Doors

Are you looking to optimize your facility’s climate control, energy efficiency, and overall operational performance? Explore Jamison’s innovative Air Door solutions designed to revolutionize the way you manage airflow and temperature within your space.

What is an Air Door?


An air door, also referred to as an air curtain, is a specialized device installed over entrances to create an effective barrier of controlled airflow. Ideal for both industrial and commercial settings, air doors enhance energy efficiency by preventing the exchange of indoor and outdoor air. They contribute to optimal climate control, reducing temperature variations and minimizing the infiltration of dust, pollutants, and insects.

AC Air Curtain

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.

The Model CAC Air Curtain

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.

DCAV Double Conditioned Air Vestibule

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.

3CAV Triple Conditioned Air Vestibule

3CAV Triple Conditioned Air Vestibule

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.

Model NPAC Negative Pressure Air Curtain

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. Supply where indicated on plans HCR Model NPAC Air Door for doorways with low temperature differentials and or for temperatures above freezing. Air Door to be powder coated cold-rolled steel. Powder coating meets 500 hour salt spray test.

Hybrid: AC & CAC with VersaFlex®

Hybrid: AC & CAC with VersaFlex®

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.

Hybrid: AC & CAC with Roll-up Doors

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 RCAV Frost-Free Airlok Door

Model RCAV Frost-Free Airlok Door

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.

PCAV Push Thru Conditioned Air Vestibule

PCAV Push Thru Conditioned Air Vestibule

A conditioned air vestibule that uses a push-to-open versus a motorized opening. PCAV® consists of two pairs of impact-type doors or fixed strips, an electrically or hot-gas heated anti-frost air-conditioning (AFC) section with patent pending PLC control, and measures approximately 16 in the direction of travel.

MCAC Miniature Conditioned Air Curtain

MCAC Miniature Conditioned Air Curtain

Miniature/small version of CAC for conveyors. The temperature differences at conveyor openings, if unprotected, are subject to the same problems as regular doorways. Prevent air infiltration and frost and ice buildup by installing HCR equipment designed to work seamlessly with your conveyor system. Conveyor units are tailored to suit your specific application in coolers, freezers, or ambient temperatures. HCR project managers and engineers will discover every detail to assure the right solution for you.
