AIR DOORS

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 build-up Double Conditioned Air Curtain Vestibule, Freezer To Cooler Specifications: Supply where indicated on plans HCR Model DCAV Air Vestibule for doorways between Freezers and Coolers.

A conditioned air vestibule that uses a push-to-open versus a motorized opening. Patent Pending Features Reduces defrost cycles by 50 to 75% Prevents extreme temperature fluctuations Dramatically reduces maintenance costs Eliminates ice on the product Removes slip hazard Decreases clean up labor Typical return on investment less than 1.5 years The Model PCAV® is an air vestibule for freezers that dramatically reduces moisture infiltration into walk-in freezers, while reducing temperature loss when the door is left open. The Air Door also eliminates ice problems, resulting in less evaporator maintenance and general ice cleanup, all providing a quick return on investment.

The Model ECAV consists of two fast-acting strip doors that create a vestibule for conditioning air and an electrically or hot-gas heated anti-frost air-conditioning (AFC) section with automatic temperature control. The ECAV is designed for medium to light-traffic freezers and high humidity situations.

The Model ASSD is a swift opening and closing motorized strip-door. Strip-door operation is easily adjusted to suit traffic speed. Features May be mounted inside the doorway or within the door jamb Recommended for doorways subjected to infiltration due to temperature differences Fully-lapped fixed strips retain 95% effectiveness Clear plastic strips significantly outlast push-through strips For negative pressure applications under 1 MPH flow-through velocity Can be used between 2 freezers without requiring any heat

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.

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.
