Cold Room Doors

Cold Room Doors

Cold room doors are an important part of cold rooms and freezer rooms, whose construction is reduced due to insulation and operating costs. Usually, there is a wide range of choices for cold room doors during the process of structural design of the cold rooms.

Doors for Cold Rooms

The main function of the cold room door is the thermal insulation of the doorway through which the products are loaded and unloaded. Therefore, the structure and hardware of the door should not have the "thermal bridges", and even if it exists, it should be reduced to a minimum. Cold room doors must be able to withstand the temperature conditions and workloads inside the cold room. Therefore, when choosing a door, it is very important to choose the correct door type and its technical characteristics (dimensions, thickness of insulation, etc.).

Types of Doors for Cold Rooms

According to the operating conditions and loading and unloading operations of the cold rooms, the following types of doors are generally used:

1. Swing doors: Swing doors are making single- or double-leafed, depending on the size of the doorway. Generally, single-leaf doors are used for doorways up to 1.2 m; double-leaf doors are usually used for larger-sized doorways. Depending on the size (height of the doorway), the door panel is fixed on two or more hinges. The door is called "right" or "left", depending on the location of the hinges and opens to the corresponding side. The advantages of the swing door are easy to install and low in price.

2. Sliding door: The panel of the sliding door moves along the guide (sli

de-rail) on the rollers. When the gate is closed, they are tightly pressed under their weight and the actions of clamping rollers, so as to provide a good sealing condition for the gate. In addition to manual opening, automatic electric drives can also be used for sliding doors, which can be activated by remote consoles, radar, photocells, magnetic rloops and a remote control.

The main advantages of sliding doors:

l Higher reliability and durability - it is a very important requirement with intensive using;

l There is no "dead zone" before entering - it is very convenient to use in confined spaces and corridors;

l The clamping device and seal. Due to the structure of guide rails and special pressure rollers, the door is automatically sealed  under the weight of the door itself;

l Possibility of using for the large doorways.

3.Vertical gate of guillotine type: When there is no space available to open the sliding door, the panel of this type of door will rise. Such doors are usually powered by electricity because they are difficult to open manually. Disadvantages of refrigeration vertical gates are: the worst tightness and higher price compared to collapsible gates.For more information please contact us at www.coldroomjl.com
