Thinking about which type of cold room is ideal for your business? Refer to this list for some guidance: Modular Cold Room This type of cold room is commonly used in the food industry. The panels and insulation materials used in this type of cold room are safe for food and are easy to clean. Modular cold rooms are commercial sized cold rooms that come in flat pack format and can be installed easily. They can freeze at any temperature range. Aside from food products, modular cold rooms are also used for non-edible but decaying products like chemical, medical goods and organic products like flowers and seeds. Combi Cold Room Combi (Combination) cold rooms have separate internal temperature zones. One is a chiller (between 2 and 12C) and the other is a freezer (down to -22C). Usually, the cold room access door leads into the warmer room (usually the chiller zone). Inside the cold room is another door that leads into the freezer. This type of cold room is ideal for various products that require different temperature ranges including food and pharmaceutical products. Walk-in Cold Room As the name suggests, this type enables you to walk right into the cold room. It can be a combi cold room or a modular cold room. This type of cold room is commonly used when the amount of products to be stored exceeds the capacity of the cabinet-sized chillers. Longwen Refrigeration specialise in this kind of cold room because it requires design and construction expertise. Industrial Chillers This type of cold room caters to numerous and bulky products. Aside from people, vehicles like forklift trucks can also enter into an industrial chiller. This type of cold room is ideal for ice factories and other big industries. Longwen Refrigeration also builds industrial chillers, offering free consultations, free AutoCAD design, free feasibility studies and free site surveys for interested parties. Custom-built Cold Room Some businesses prefer a custom-built cold room, allowing them to design the cold room according to their preferences. Longwen Refrigeration is a trusted and reputable cold room specialist that employs talented and accommodating people to help you design your cold room layout. They can also manage the entire construction process for you.

Refrigerated Warehouse Types & How to Select 1. Cold Storage Warehouse Types Based on Refrigerating Temperature Range High temperature walk-in cooler cold storage warehouse Temperature Range: 5ºC to minus 5ºC. The storage purpose of this refrigerator cold room is for refrigerated storage of food like vegetable, fruit, egg, pharmaceutical material, floral, wood and other things suitable for this temperature range. Medium temperature walk-in freezer cold storage warehouse Temperature Range: minus 10ºC to minus 18ºC. The storage purpose of this freezer cold room is for frozen storage of food like meat, seafood and other things suitable for this temperature range. Low temperature walk-in freezer cold storage warehouse Temperature Range: minus 23ºC to minus 28ºC. The storage purpose of this deep freezer cold room is for the frozen storage of ice cream and other deep frozen food etc. Ultra low temperature walk-in freezer cold storage warehouse Temperature Range: lese than minus 30ºC. The storage purpose of this ultra low temperature cold room is mainly for fast frozen food, industrial laboratory test room, medical treatment, blood bank, etc. To design a cold storage plant, besides considering the size of the cold storage warehouse, the important thing you need to consider for a refrigerated warehousing project is to select the suitable refrigeration temperature of the refrigerated warehouse. The temperature of the cold room plant shall not be too high or too low. 2. Cold Storage Warehouse Types Based on Installation Structure: Civil construction refrigerated warehouse The space enclosing structure wall material of the cold store room is made of brick and the heat insulation material is made of sprayed polyurethane (PU foam). Assembling refrigerated warehouse The space enclosing structure wall material of the cold store room is made of prefabrication modular cold room insulated panel (insulated foam panel). The foamed insulation material of the cold room panel is polyurethane (PU panel). To build a civil construction refrigerated warehouse or assembling refrigerated warehouse, you need to consider your local building construction and local building cost on the refrigerated warehousing storage project. We prefer to build a assembling refrigerated warehouse because the prefabricated modular cold room panel (insulated sandwich PU foam panel) can be installed and disassembled at any time and it is very convenient to move the cold storage warehouse to another installation place. Refrigerated Storage Requirements of Food and Physical Nature Before you decide to design and build a walk-in cooler or walk-in freezer cold storage warehouse, you need to first know what is the best storage temperature of the cold room plant to store your food material or other materials. In this way, you can avoid to build a refrigerated warehouse which is not cool enough to store goods or is too freezing and to freeze & destroy the food and waste investment money on cold storage plant project cost because the colder temperature requires bigger powerful compressor and refrigeration system.
