The difference between the cold storage insulated door and ordinary doors is that it needs to be insulated, because the cold storage insulated door is actually equivalent to an insulating structure that can be movable opened and closed, and is the only way for goods to enter and exit the warehouse.
💡 Key Design Considerations
The design and management of the cold storage insulation door is directly related to the service life of the entire cold storage. Due to the entry and exit of goods, the cold storage insulation door is opened frequently. When the storage door is opened, the hot and cold air inside and outside the storage is cooled and heated near the door opening. In exchange, the walls, floors, ceilings, etc. around the door opening are prone to condensation, dripping, frost, freezing and other phenomena. Therefore, in addition to trying to improve the heat and steam insulation performance of the cold storage door and strengthening the sealing performance of the door, some other effective measures must be taken, such as installing air curtains, setting up door buckets, electric heating, and other measures.
Technical Specifications
✓ Core: Polyurethane Foam
✓ Surface: PPGI (Color Customizable)
✓ Material: Stainless Steel SUS304
✓ Size: Fully Customized
Semi-Buried Swing Door – Single / Double Opening
The semi buried door adopts a pre factory integrated finished product structure, which is easy and convenient to install and meets all the technical requirements of cold storage doors. The frame aluminum alloy profile is spliced and connected to the frame board on site, making it easy to install.
Fully Buried Swing Door
Fully buried door, characterized by the door body being level with the door frame, beautiful appearance, good sealing and insulation. Suitable for cold storage, low-temperature processing workshops, insulation devices, with moderate door size and frequency of opening. With polyurethane foam forming inside, no cold bridge, and good insulation performance.
Heavy Rotary Shaft Door – Double / Single Opening
The rotary door is a hinged door, which can be single or double opened. When the moving position of the sliding door is not enough or the insulation effect is required to be high. The door frame can use a dedicated rotary shaft door aluminum alloy net frame, with superior sealing performance.
Standard Manual Sliding Door – Single / Double Opening
The manual sliding door has the high-strength aluminum alloy thickened guide rail, and shares a single track. It floats and sinks, making it easy to open and operate smoothly. The silent effect is good, the sealing effect is better, the insulation is good, and the service life is long.
Lightweight Manual Sliding Door
The size of the door body is moderate, the structure is simple, and the internal polyurethane is foam formed as a whole, with good sealing and thermal insulation; At the same time, it has a safety device for escaping danger in the warehouse, which is safe and practical. Applied in industries such as food, supermarkets, warehousing, pharmaceuticals, and retail.
Electric Single Sliding Door
Electric single sliding door, equipped with an electric control system on the basis of manual opening sliding door, independently developed and easy to install. High torque: DC brushless motor, no need for clutch worm gear; Powerful function: equipped with anti-pinch, delay switch, full range three-stage continuously variable speed.
Electric Double Sliding Door
Electric double sliding door, independently developed and easy to install; easy to operate: One click self-learning (measuring door width); Simple structure: No need to connect other electrical components externally; High torque: DC brushless motor.
Air-Conditioned Gas Regulating Door
The insulation of the door panel is made of polyurethane integral foam, and the door frame is made of all aluminum alloy. The airtight strip adopts special high-quality sealing strips with high compression resistance, high elasticity, and low temperature resistance.
Anti-Collision Free Door
The door panel is made of 304 stainless steel panel and molded with polyurethane foam. Built-in ABS observation window, ensuring the safety of personnel. The flexible anti-collision board material effectively absorbs the impact force. It automatically closes tightly after personnel or vehicles pass through.
Frequently Asked Questions
?What is the core material used in cold storage insulated doors?
The core material used in cold storage insulated doors is polyurethane foam. This material provides excellent thermal insulation with no cold bridge, ensuring stable low-temperature environments inside the cold storage facility.
?What is the difference between a semi-buried swing door and a fully buried swing door?
A semi-buried swing door uses a pre-factory integrated structure making installation simple and flexible. A fully buried swing door features a door body that sits flush and level with the door frame, offering superior sealing and better insulation performance.
?What are the advantages of the electric sliding door over the manual sliding door?
Key advantages include one-click self-learning for automatic door width measurement, a DC brushless motor for high torque, anti-pinch protection, delay switch functionality, and three-stage continuously variable speed control.
?Can cold storage insulated doors be customized in size and surface material?
Yes, all doors are available in customized sizes. The surface material can be chosen between PPGI (customizable colors) and stainless steel SUS304 (customizable thickness).
?What industries are cold storage insulated doors suitable for?
They are used in food processing, supermarkets, pharmaceuticals, medical cold chains, warehousing, logistics centers, and low-temperature workshops.
?How does the anti-collision free door protect personnel and equipment?
It features a built-in ABS observation window for two-way visibility and flexible anti-collision boards that absorb impact force, reducing injury risks and extending the door's service life.
