By combining an air door with your currently installed door, you are ensuring 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.

Features

• Maximizes the energy efficiency of a roll-up door
• Effectively reduces moisture infiltration
• Significantly reduces air exchange between rooms of differing temperature
• HCR Model AC and CAC is retrofittable to existing roll-up doors of any brand
• Additional air doors can be added in a modular process to keep maximizing energy efficiency as door open time increases
• Warm side or cold side mounts

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.

FEATURES

• No frost, fog or icing
• Eliminates safety hazards
• No haze within cold room
• Reduced maintenance costs
• No frost on stored products
• Reduced refrigeration loss
• Reduced coil defrosting burden
• Increased warehouse productivity
• Improved refrigeration cycle efficiency
• Sublimates existing frost buildup

Miniature/small version of CAC for conveyors.

MCAC Miniature Conditioned-Air Curtain The temperature differences at conveyor openings, if unprotected, are subject to the same problems as regular doorways. Prevent air infiltration, 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.

Features

• Prevents air infiltration
• Prevents first buildup
• Prevents ice buildup
• Protects the differences in temperature

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

Features

• Single nozzle and intake
• Proprietary nozzle design
• Greatly diminishes one-way air flow caused by building air imbalances
• Horizontal, curvilinear, recirculatory air flow
• Powder-coated steel
• Metal-clad insulation when required

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.

Features

• Elimination of ice, frost, condensation, fog and haze
• No frost on stored product, ceiling, walls, racks or floor
• Reduced moisture gains into freezer
• Reduced refrigeration loss
• Reduced infiltration air into freezer
• Reduced compressor runtime and defrost cycles
• Improved refrigeration cycle efficiency
• Improved visibility and safety
• Improved productivity and energy efficiency
• Reduced maintenance costs
• Existing ice and frost buildup sublimates
• Great return on investment (ROI)
