SEMI BURIED SINGLE OPENING COLD STORAGE DOOR

Aqua Route Semi-Buried Single Opening Cold Storage Door features a unique semi-recessed design where half of the door body is embedded into the door frame, providing superior sealing and thermal insulation. The door shell is composed of plastic profiles and panels, with integral polyurethane foaming inside, eliminating thermal bridges and delivering excellent insulation performance. The door frame is equipped with a self-limiting temperature heating tape, requiring no additional temperature control or switch. The sealing strip uses flexible plastic with a built-in magnetic strip for outstanding airtightness. All hardware is made of stainless steel or high-strength galvanized material for long-lasting durability. The door lock includes a built-in escape device for enhanced safety. Suitable for all types of cold storage, freezer rooms, and high-temperature warehouses, with an operating temperature range from -95℃ to +160℃.
