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.
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 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.
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.
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.
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.
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.
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.
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.
