Model ECAV Frost-Free Airlok-Door™

Strip curtains can be added to all HCR models for even greater efficiency in the conditioning process. 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, and measures approximately 28.5" in the direction of travel.
