Better climate control: The recirculatory air door dramatically reduces ice, fog and moisture associated with wide-open doorways.

No interference with daily operations: AirSeal’s invisible dual air barriers allow for unobstructed traffic flow with reduced refrigeration loss and/or heat gain.

Low maintenance: This air door is constructed using galvanized or stainless steel for easy cleaning.

Easy operation: Easily control air speed with the integrated self-regulating EPLC unit, allowing for precise application settings and optimal air mixing temperature control.

Cost-efficient: This air door reduces coil defrosting burden and improves refrigeration cycle efficiency. This air door also eliminates maintenance costs associated with hard panel doors and does not need energy-consuming infrared heat lamps.



A recirculatory air door with a built-in air barrier

AirSeal creates an invisible barrier utilizing high velocity laminar air flow to maintain dual climates, keeping your cold side cold and your warm side warm. Enviro’s 715D double horizontal recirculatory air door is a “smart door” that automatically adjusts to your temperature and humidity changes while maximizing energy efficiency with superior optimization control.

Reduce excess moisture build-up in coolers and freezers

By monitoring and adjusting to any environmental changes, the double horizontal recirculatory air door will significantly reduce fog, ice build-up and moisture commonly associated with wide-open doorways when air exchanges between two different climates. With reduced refrigeration loss/heat gain, no door to maintain and only one moving part, AirSeal is energy-efficient and reduces long-term maintenance costs. In addition, AirSeal doors provide unlimited material handling efficiency with complete visibility through your door openings.
