FULLY BURIED COLD STORAGE DOOR
Aqua Route Fully-Buried Cold Storage Door features a fully-recessed design where the door body and frame sit perfectly in the same plane. It automatically presses tightly when closed, delivering superior sealing and thermal insulation with a clean, elegant appearance. The door shell is composed of plastic profiles and panels with integral polyurethane foaming inside, eliminating thermal bridges for 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 on the interior side for enhanced safety. Suitable for small cold storage rooms and freezer rooms 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?
