Cold chain industry fresh-keeping warehouse, refrigerator, freezer (installed on the high temperature side)

W 1800mm * H 2400mm

Opening speed not less than 1.5m/s. Adjustable.

Closing speed not less than 0.6m/s. Adjustable

he electric heating system has a dual-circuit design to prevent the rails from freezing due to heat exchange caused by frequent door operation.The motor control system has a door curtain anti-freezing function. The door curtain will automatically move up and down several times at a low amplitude every certain period of time (adjustable).

Adopt roller type lifting method.

The inner and outer sides are made of high-strength fiber PVC low-temperature resistant curtains, and the interior is filled with aluminum foil polyethylene insulation material. The total thickness of the door curtain is 25mm-30mm.Outer coating PVC thickness 0.9mm, 600N/600N (warp/weft), tensile strength: 5700/5100 (warp/weft) N/5 cm, operating temperature -35℃--+70℃.

The rail is made of aluminum alloy, and the surface of the aluminum alloy is electrophoresed to ensure that it will not oxidize and rust. It has a rail sealing device and a self-constant temperature heating system.

The control box and motor comply with various national electrical safety standards and are waterproof and dust proof even in harsh environments.

It uses a servo motor and servo control system specially designed for cold storage with a Chinese operation interface, easy debugging, accurate positioning, fast information feedback and abundant external ports. The servo motor outputs constant torque to ensure that the door can be opened and closed more than a thousand times a day.

The track guide limit system, door curtain windproof rod, door curtain and guide rail are closely matched, and the material has strong wear resistance, which ensures the overall wind resistance and can withstand winds of level 8.

The guide rail side seal, door opening top seal and door bottom seal ensure the air tightness and isolation effect inside and outside the door.

Equipped with infrared safety protection electric eyes : Infrared shooting electric eyes are installed on both sides of the door frame. If there is an object under the fast door, the door will remain open. When the door body is lowered, if there is an object below, the door body will open to the most open position and then delay the descent when there is no obstacle below.

Manual control by control box button and inner waterproof auxiliary switch.Optional control: pull rope switch (low temperature waterproof type); interlock opening; remote control opening; geomagnetic opening; low temperature radar opening and other control methods.
