Rigid polyurethane foam is the internationally recognized best building material. Polyurethane sheets have a low thermal conductivity, good load resistance and high flexural strength. It does not absorb water and is anti-corrosive, resistant to insects and is not easily bitten by rats. It has good fire resistance and a large heat resistance range. The metal plate has been placed on a specially designed mold. By means of the spraying device, the polyurethane foaming agent is sprayed on the metal plate and is automatically controlled by a computer to form a foaming agent between the metal plates, so that the three layers complete the color steel laminated PU plate at one time. Metal sheet materials can be selected according to customer requirements, such as stainless steel, embossed aluminum and so on.
The door is made of high-quality materials: a fully enclosed frame structure, rigid polyurethane foam. Color steel is used inside and outside the door (choose materials according to customer requirements, such as stainless steel, embossed aluminum, etc.). There are different types of doors due to different opening and closing methods - hinged doors, sliding doors and electric sliding doors.
The cold storage unit is composed of a refrigerating compressor, a condenser, a compressor oil separation device, a liquid storage device, a gas-liquid separation device, a solenoid valve, a pressure control device, and a heat dissipation motor. The cold storage unit can be assembled according to the actual cold demand and different refrigerating devices required by the customer. The refrigeration capacity of the cold storage unit can be between 1KW and several hundred KW, which can meet various cold occasions.
