The freezer fast door is a door suitable for cold storage rooms and fresh-keeping rooms. The effective range is above 0℃. When you want to install a freezer fast door for your cold storage room, but feel that the ordinary freezer fast door cannot withstand the temperature low enough, then we can provide you with a better choice - a double-track freezer fast door.
We design double-layer tracks and double-layer door curtains for double-layer cold storage rapid doors. There is a certain distance between the two layers of door curtains. The static air between the two curtains can reduce the speed of heat transfer.
This design makes the product's thermal insulation effect better, while also retaining the characteristics of the high-speed door.
