Gerald Doors
1 / 5
Low temperature cold storage fast doors are mainly used in smart livelihood engineering projects. Technology is combined with 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, it focuses on providing energy-saving solutions for fresh storage, refrigeration, and refrigeration logistics channels. Committed to assisting cold chain logistics enterprises in improving work efficiency in cold storage areas and saving energy operating costs.
| Heating and antifreeze device | The design and application of the heating mechanism avoids the freezing of the guide rail caused by frequent operation, ensuring stable operation in low-temperature environments (-40°C to 0°C). Includes imported heating line. |
| Lifting method | Double drum lifting method |
| Opening speed | 0.8-1.5M/s (Adjustable) |
| Closing speed | ≥ 0.6M/s (Adjustable) |
| Door curtain | 5-6 layers with thickened PVC insulation. Sandwich made of special insulation materials (15mm-25mm total thickness). Special PVC sealing on both sides prevents cold air leakage. |
| Track | Aluminum alloy material (3.0mm thickness); Cover box frame made of 304 stainless steel. |
| Insulation protection | Control box (stainless steel) and components meet IP64+ standards, waterproof and dustproof for harsh environments. |
| Control system | Low-temperature resistant special stainless steel control box |
| Motor | Low-temperature resistant stainless steel motor (1.5 kW power) |
| Limit mode | Electronic limit mode via multi-turn absolute encoder for stability and reliability. |
| Wind resistance | Strong wear resistance and guide rail matching. Meets national standard wind resistance level 6-8. |
| Sealing performance | Top and bottom seals effectively isolate air pressure convection, enhancing airtightness. |
| Safety devices | 1. Infrared safety protection: Radio eyes on both sides; 2. Bottom safety protection edge: Automatic rebound when obstacles are detected. |
1. Three-sided heating structure design of door body to prevent frosting.
2. The door curtain shakes up and down in a short frequency periodically to prevent frosting and freezing.
A pair of infrared protection devices are installed on both sides of the door to ensure maximum safety for personnel and goods.
1. Double-layer low-temperature resistant special environmental protection door curtain, filled with polymer thermal insulation material.
2. Wavy structure to improve lateral strength and stability.
