Semi-Flush Retrofit Door (Double Opening)
Frostlink double opening swing doors feature a pre-fabricated structure, making installation simple and convenient, and fully meeting the technical requirements of cold storage doors. Double locks are strategically placed within the door seams, increasing clamping force and the number of support points to ensure a stronger seal. The flexible PVC plastic profile incorporates a magnetic strip, effectively compensating for manufacturing errors and achieving excellent sealing performance.
The door body is made of PVC profiles and panels molded as a single piece, with polyurethane foam filling inside. The aluminum alloy frame is assembled on-site and connected to the cold storage panel, making it particularly suitable for the renovation and expansion of cold storage, low-temperature processing workshops, insulation systems, and prefabricated warehouses. It is widely used in the food, supermarket, warehousing, pharmaceutical, and retail industries.
- Door Thickness: 75 / 100 / 120 / 150 mm
- Temperature Range: -45°C ~ +50°C
- Panel Material: Color steel / Stainless steel
Product Highlights
Superior Thermal Insulation
High-density polyurethane foam core (40kg/m³ ±2) + thermal break aluminum frame eliminate cold bridges, delivering excellent heat resistance and significantly reducing energy loss.
Advanced Sealing Technology
Multi-layer EPDM gaskets (triple-layer where applicable) ensure tight compression and superior airtightness, minimizing air leakage and maintaining stable temperatures.
Built-in Safety & Flexible Customization
Standard emergency escape lock + internal handle for personnel safety; full customization in size, thickness, material, and optional features (heating, electric drive, air curtain) to meet exact project requirements.
Robust & Corrosion-Resistant Construction
Anodized aluminum alloy frames, high-grade nylon hardware, and anti-corrosion treatment provide strong durability against moisture, low temperatures, and daily wear.
