The cold door adopts a high-quality material after special treatment to make a frame, overlay the metal panel, disposable whole polyurethane foaming. The joint of the door fan and the door frame adopts a special shape, and it is resistant to low temperature and strong elastic rubber materials. The two plane forms are sealed and the sealing performance is improved. It is surrounded by low voltage and high efficiency electric heaters to prevent door fans and door frames from freezing. There is a safety switch on the side of the door. When the door is closed, if the person or vehicle is in danger, it can be opened in the cold storage to avoid accidents. It can be used in combination cold storage with a temperature of not less than -60 °C, a constant temperature storage, and a constant temperature workshop. The temperature difference between indoor and outdoor is greater than 80 °C, and the air temperature outside the storage is greater than 80 %.1. Open the door flat: Lengkuping opens the door, applicable temperature -35 °C ~ 40 °C, specifications can be customized according to customer needs. Custom door hole size door panel thickness can be customized, can be equipped with heating wire in the door frame, and the use of imported door locks and hinges, good thermal insulation performance, easy to open.
2. Semi-buried door: Cold storage semi-buried door, simple and compact processing structure, manufactured with special pressing molding process. The inner insulation material adopts rigid polyurethane and its measurement value = 0.025 W/m2. K. The thickness is generally 100mm, 120mm, 150mm, and the weight of the three volumes is about 40-50Kg/m2. The surrounding rubber seals are highly oil-proof and anti-aging, and they can be easily assembled and replaced without special tools.
3. Flat door: Translational cold door insulation door, with good thermal insulation seal performance, small manual opening and closing torque, small opening and closing noise, safety and reliability. Heat insulation door can be configured according to customer requirements electric door opening device.
