Types Of Cold Storage Doors

Manual type - manual sliding door
The door leaves are made of high-quality materials, with a fully enclosed overall frame structure and hard polyurethane foam. The door leaves are covered with stainless steel both inside and outside, and can be selected according to user requirements, such as painted color steel plates, galvanized plates, or aluminum plates. The opening and closing of the door leaf adopts a manual push-pull translation method, and the top track adopts a curved form. When the door is closed in place, the door leaf automatically presses the floor and door frame. Ensuring good sealing performance. When opened, the door leaf synchronously leaves the door frame and rises, reducing the friction between the sealing rubber strip and the door frame and floor. There are low-voltage electric heaters around the door leaf to prevent freezing of the door leaf and door frame at low temperatures. The door is also equipped with an internal escape device. When the staff accidentally locks it in the warehouse, simply pull the internal escape ring and pull the handle inside the door to open it smoothly. This manual sliding door has the characteristics of reasonable structure, no moisture absorption, no rust, no deformation, light weight, good insulation performance, and small footprint. It is currently an advanced, beautiful, and ideal refrigerator door.
Electric type - electric sliding door
The electric refrigeration door is made of high-quality materials with a specially processed frame, covered with metal panels, and made of disposable polyurethane foam. The joint between the door leaf, floor, and door frame is made of specially shaped rubber material that is resistant to low temperatures and has strong elasticity. It is sealed in two flat forms to improve sealing performance. Low voltage and high-efficiency electric heaters are installed around the door to prevent freezing of the door leaf, door frame, and floor. One side of the door leaf is equipped with a safety switch. When the door is closed, it can automatically open in case of danger to people or vehicles, avoiding accidents. The three-phase conical motor is used for rotation, which drives the chain to rotate after deceleration. The rotating parts are equipped with rolling bearings. The track adopts a curved form to automatically lower when the door is closed in place, compressing the floor and door frame to ensure good sealing performance. When the door is opened, it synchronously rises and separates the door frame, reducing the friction between the sealing strip and the door frame and floor, making it easy to open and tightly closed. The door is also equipped with manual and internal unlocking devices in case of power outage or malfunction. The electrical appliances are selected from high-quality products, with advanced and unique control design. Therefore, this product has the advantages of advanced structure, beautiful appearance, good sealing performance, flexible control, and long service life.
Manual pneumatic control - sliding pneumatic control valve
This series of manual air control valve is developed repeatedly according to the new requirements of fresh-keeping technology and foreign technology, which solves the technical problem that the air control valve cannot reach the highest international air tight standard in air tightness. Compared with foreign countries, it has certain uniqueness and progressiveness in air tightness, opening and closing, and cost.
The door leaf insulation adopts polyurethane integral foam, the frame is made of all fiberglass, and the outer packaging adopts stainless steel plate, color steel plate, etc. The track adopts the form of multi bearing straight running, which makes the door leaf more light and flexible to open and close. The air sealing strip adopts the special high-quality sealing strip with compression resistance, high elasticity, low temperature resistance and corrosion resistance, which is more scientific and internationally progressiveness in general, and is indeed the most ideal supporting door for the air-conditioned warehouse.
