Which Rapid Door is Better for Your Cold Storage?

August 25, 2025

In industries such as cold chain logistics and food processing, the performance of the door is directly related to the temperature stability and operational efficiency of the cold storage. Especially in cold storage environments with different temperature zones, it is important to choose the right door for the job.

With the development of technology, many kinds of different functions, suitable for different places of the door is gradually developed. One of the most popular doors for cold storage is the fast door.

The origin of fast doors for cold storage

In the 1950s and 1970s, modern cold storage technology has been slowly popularized, but with the door is still the traditional heavy and inconvenient to open the insulation manual sliding door. The opening of this door is too labor-intensive and slow. Resulting in frequent opening very much affects the efficiency of work, and cold air loss is serious, the energy consumption of cold storage remains high.

Therefore, in the eighties, there are enterprises in the cold storage introduced the concept of fast door. To the nineties, with the development of cold chain logistics cold storage special rapid door gradually specialized. Manufacturers of fast doors began to develop fast doors that are more suitable for cold storage, taking into account both heat preservation capacity and opening speed.

To the twenty-first century, the development of technology is more mature, a variety of intelligent equipment also began to be integrated into the system of the rapid door of the cold storage. And some manufacturers also according to the cold storage insulation needs and procurement budget of different research and development of different styles of cold storage fast door.

Today, we will provide you with a detailed introduction to two common types of cold storage fast door: refrigerated fast door and Rite models of cold storage fast door, they are suitable for different cold storage and freezing environment, to provide customers with more professional, cost-effective procurement options.

Refrigerated Fresh Door: Designed for cold rooms above 0℃

Cold storage fast door is upgraded and optimized on the basis of ordinary PVC fast door, mainly used in cold storage space above 0℃, such as food preservation warehouse, fruit and vegetable storage room, fresh food sorting area.

Consumer behavior shifts dramatically in the weeks leading up to Black Friday. People actively search for deals and discounts, often holding off on purchases until they know they can get the best price. The anticipation drives more consumers online, looking for deals across various platforms and devices. This heightened demand creates a lucrative window for businesses to attract shoppers with targeted marketing efforts.

Here are some other reasons this holiday is a golden opportunity you shouldn’t miss out on:

Upgrade door curtain structure, improve heat preservation performance

Different from the traditional single-layer PVC door curtain, the cold storage and preservation fast door adopts double-layer PVC door curtain, filled with high-density heat preservation material in the middle, which significantly enhances the heat insulation effect and airtightness, effectively slows down the temperature exchange and maintains the constant temperature of the cold storage.

Stable structure, suitable for high-frequency access

The door structure continues the standard fast door design, with high-speed opening (0.8-1.6m/s), silent operation, wind and dust resistance, etc., especially suitable for high-frequency goods and personnel in and out of the cold storage environment, taking into account energy saving and efficiency.

Zipper design to reduce cold air loss

The connection between the door curtain and the track adopts zipper design, which is more airtight than ordinary brush. When the door is closed, it can avoid the exchange of hot and cold air from the gap.

Friendlier price, lower purchasing budget

As this kind of door for cold rooms above 0℃ has a lower heat preservation capacity than the advanced cold storage fast door, the price is also lower. It is able to reduce the procurement cost for places that do not require too much insulation capacity.

Wide range of applications

Fresh food distribution centers: fresh food usually only needs to be kept refrigerated, freezing will make it lose its freshness. Therefore, this kind of place is very suitable with refrigerated fast door.
Supermarket refrigerated warehouse: large supermarkets usually have a large number of products in stock. Many products only need refrigerated storage, and usually in and out will be very frequent. Therefore, the use of refrigerated fast door is the optimal choice.
Pharmaceutical insulation warehouse: some drugs or medical supplies have temperature requirements, but not to the extent of freezing. This is where a refrigerated fast door is appropriate.

Rite type freezer rapid door: 0℃~-35℃

Rite freezer rapid door is a professional cold storage door products, for 0 ℃ below the deep-freezing cold storage or quick-freezing room development, to solve the ordinary fast door in the cold environment can not operate normally.

Heavy curtain design, strong heat insulation

The door curtain is a multi-layer composite structure, and its thickness is significantly higher than that of ordinary fast doors. Built-in high-density thermal insulation cotton, with excellent thermal insulation and low temperature resistance, even in -35 ℃ cold storage can also ensure that the internal temperature is not easy to lose.

Anti-freeze heating for low-temp operation

The guide rail and the bottom are equipped with anti-freezing heating wire as standard to prevent the door curtain from jamming and freezing due to icing. Keep the equipment running smoothly for a long time, realize all-weather low-temperature automatic opening and closing, and ensure the efficiency of entry and exit.

Intelligent reset system, safer from collision

The upper left and right corners of the door curtain are equipped with reset wheels. When the door curtain is misaligned due to impact during operation, the reset wheels can automatically guide the door curtain back to the track, which effectively improves the equipment life and reduces the maintenance frequency.

Suitable for extreme frozen environments

Quick-frozen processing room: Quick-frozen processing place in order to achieve the purpose of quick-frozen usually very low temperature, ordinary door will freeze, can not operate normally. Only cold storage fast door or cold storage sliding door with heating wire is suitable.
Cold chain logistics center: Cold chain logistics centers usually need to carry goods in and out of the cold storage frequently. Cold storage fast door can not only keep warm, but also ensure the efficiency of personnel in and out.
Medicine/vaccine freezing storage warehouse: medical supplies such as hormones, vaccines, plasma, etc. are usually kept below 0℃. Cold storage fast door can not only heat preservation, but also can let the medical personnel without contact fast in and out, greatly ensure the clean degree, reduce bacterial contamination.

Freezer rapid door can be matched with what intelligent accessories?

The motor of the rapid door is more advanced and can access many accessories. For example, radar, infrared sensor, police lights, geomagnetic and so on. These accessories are great for increasing the efficiency and safety of the passage. They are optional when purchasing a door or can be purchased separately.

Refrigerated vs Cold Storage Doors: How to Choose

Type	Applicable temperature	Door curtain structure	Whether with heating system	Automatic reset	Price	Main application
Refrigeration and freshness fast door	Above 0℃	Double-layer heat preservation PVC door curtain	None	None	Price-friendly	Fresh storage, fresh warehouse, cold room
Rite Coldroom Rapid Door	0℃ to -35℃	Multi-layer thick curtain + thermal insulation cotton filling	Guide rail with heating wire	with reset wheels	More expensive	Deep freezer, quick-freezing workshop, medicine freezing storage

Suggestion for selection:

If your cold storage temperature is above 0℃, I recommend the (Refrigerated Fresh) Cold Storage Fast Door, the heat preservation ability is enough and the price is more friendly.
