 Automatic cold room sliding door

Sealing strip

All-round EPDM with excellent resistance to high and low temperature, ozone and atmospheric aging, as well as good dielectric, water-repellent, physiologically inert characteristics

Working temperature is -50°C~+130°C.

Door leaf

Aluminum profile and steel panel are combined to form the shell, inside which the polyurethane foams. It’s cold-bridge-free with perfect insulation.

Steel choice : painted steel, stainless steel, aluminum steel.

The emergency escape device allows the door to be opened from inside when locked.

Drive system

There’re worm-gear motor and synchronous belt to transmit the motion. Electromagnetic clutch is used to convert between electric and manual operation, which makes sure of the safety and practicability.

Electronic control system

Famous brand such as Schneider electrical components ensures the reliability and durability of electric control system. PLC programmable controller has greatly simplified the circuit. Only external switching value signal components are connected to the PLC. The PLC collects switch electrical signals for centralized processing, the program designs all kinds of trigger conditions correspond to different situations, makes it possible for delayed  automatic closing and for deciding when to start delaying function. The function makes the door control perfect.
