1. Extreme weather resistance

Operates reliably in a wide temperature range from -45°C to +110°C, unaffected by extreme cold or high-temperature cleaning conditions, ensuring stable performance year-round.

2. Electric heating anti-freeze

The door frame is embedded with imported stainless steel alloy wires and silicone rubber heating strips around its perimeter, which effectively melt frost accumulation at the door seams when powered on, preventing difficulty in opening and sealing strip tearing.

3. Premium Sealing System

The imported EPDM rubber sealing strip is molded in one piece, combined with the clamping force provided by the rotating shaft structure, significantly improving airtightness compared to conventional hinged doors.

4. High-pressure integral foaming

Polyurethane high-pressure one-time injection foaming, fully enclosed monocoque frame, fine and uniform foam cells with no shrinkage marks, smooth and sturdy door surface, excellent thermal insulation performance.

5. Cold bridge break door frame

The door frame features an aluminum alloy/stainless steel thermal break design, which interrupts the metal heat conduction path, significantly reducing cold loss and condensation on the frame.

6. Integrated long shaft structure

Abandoning traditional split hinges, this design features a single thickened stainless steel pivot bearing that offers high impact resistance, prevents deformation, allows for a wide opening angle, and ensures long-lasting durability.
