Low temperature cold storage quick doors are mainly used in smart livelihood engineering projects. The company combines servo technology, sensing technology, and communication technology to make cold storage door products intelligent, technological, digital, modular, and user-friendly. While ensuring safe and stable operation, the company focuses on providing energy-saving solutions for fresh-keeping warehouses, freezers, and refrigerated logistics channels. Committed to assisting cold chain logistics enterprises in improving the efficiency of cold storage areas and saving energy operating costs.

Name：Low temperature cold storage quick door。

Heating and antifreeze device：The design and application of the heating mechanism avoid the freezing of the guide rail caused by heat exchange due to frequent operation of the door body, further ensuring the stable operation and working efficiency of the door body in low temperature environments, with a working temperature ranging from 60 ° C above zero to 38 ° C. Imported heating wire。

Lifting method：Double drum lifting method。

The maximum：opening speed is 0.8-1.5M/s, adjustable。

Closing speed：The closing speed is not less than 0.6M/s and adjustable。

door curtain：The entire door curtain has 5-6 layers, with thickened PVC insulation curtains inside and outside, and insulation materials used for the sandwich, with a total thickness of 15mm-25mm; Both sides are sealed with special PVC, which has good sealing performance and prevents cold air leakage and hot air from entering. There are multiple colors available for customers to choose from。

track：The track is made of aluminum alloy material with a thickness of 3.0mm; The frame of the private room is made of 304 stainless steel material。

Insulation protection of door components: The control box (stainless steel) and other components must meet IP64 or above, and comply with various national electrical safety standards. Even in harsh environments, they can be waterproof and dustproof。

Control system: Baojiu low-temperature resistant stainless steel control box。
Motor: Baojiu low-temperature resistant stainless steel control motor with a power of 1.5 kilowatts。
Limit form: electronic limit method, which can be directly set in the control box; At the same time, the main accessories of the electronic limit switch adopt a multi turn absolute value encoder to ensure stability and reliability。
Wind resistance strength: The door curtain guide components, door curtains, and guide rails in the door operation guidance system are tightly matched, and the material has strong wear resistance, ensuring the overall wind resistance ability, which can meet the national wind resistance level of 6-8。
Sealing performance: The structural design and application of the top and bottom seals of the door body can effectively isolate the air pressure convection on both sides of the door body, further enhancing the airtightness performance。
Safety device: 1. Infrared safety protection: There are photoelectric eyes on both sides of the door frame, and there is an object under the quick door to keep it open; When the door descends and an object passes below, the door will open to its most open position and wait until there are no obstacles below before delaying the descent。
2. Bottom safety protection edge: When the door is descending and the object is in the blind zone of infrared safety protection, if the door presses against the obstacle below, the door will quickly rebound and open the door at the maximum speed, effectively protecting the object or pedestrian below from accidents. (Standard configuration)。
Open control: Control the operation interface button of the control cabinet. Optional control methods: radar, ground magnetic ring induction, Bluetooth radio frequency, remote control induction, rope switch and other multiple methods。
