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℃.

PIR (Polyisocyanurate) and PUR (Polyurethane) panels deliver thermal conductivity (λ) values of 0.022-0.025 W/mK — significantly better than EPS or rock wool alternatives. This translates directly to lower compressor energy consumption and reduced operational costs. Standard effective widths: 1120mm (mechanically produced) and 960mm (hand-assembled). Yes. Our PIR/PUR panels are CE certified and manufactured under ISO 9001:2015. We provide fire resistance test reports and SGS verification documentation for all export orders. Our high-precision tongue-and-groove joint system uses specialized gaskets and cam-locks to create a continuous thermal envelope, eliminating both air leakage and thermal bridging — the two primary causes of frost buildup in cold storage facilities. Yes. We provide installation manuals, video tutorials, and remote technical consultation. Engineers are available for on-site guidance on large-scale projects. For tropical environments with ambient temperatures of 33-36°C, 100-120mm PUR/PIR panels are standard. For continuous 24/7 operation or high door-opening frequency, 150mm panels reduce compressor energy consumption by approximately 20-25%. Q1: Why are PIR and PUR panels preferred for cold storage construction?
Do your cold storage panels meet international safety and quality standards?
Q3: How do you ensure airtightness and prevent thermal bridging?
Q4: Can you support international cold room installations?
Q5: What panel thickness is recommended for -18°C deep-freeze in tropical climates?
