A conditioned air vestibule that uses a push-to-open versus a motorized opening.
U.S. Pat. No. 10,921,049 and Patents Pending
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.
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.
