Changzhou Yuyan Refrigeration Technology Co., Ltd. and Changzhou Yuyan Refrigeration Equipment Co., Ltd. is a leading cold storage production plant as well as an overall energy efficient solution provider as one of China's largest energy efficient manufacturers of cold storage panels.
Yuyan's cold storage solutions use excellent insulation properties inside polyurethane insulation sandwich panels for an accurate temperature control. Widely used in agriculture, animal husbandry, bio-pharmaceuticals, chemicals, and food processes, these panels are extremely versatile.
We provide a full range of services to our customers with energy saving insulation systems for the design, construction, production and maintenance of each cold storage project.Service & Technology
The cold storage units are intended for cooling and storage of perishable products-either cold or frozen.
1. These units are built using polyurethane sandwich panels. They are easy to mount or disassemble and enlarge if necessary.
2. The panels are joined through fast action eccentric mechanisms.
3. The external and internal panel covers are made of zinc coated steel sheets with a plastic finish. The heat insulation is a rigid foam polyurethane.
4. The floor panels are reinforced and able to withstand a load of up to 2,000kq/square meter.
5. Each cold storage unit is equipped with electric lighting. Freon 22 and 404A are used as refrigerants.
6. The prefabricated cold rooms are intended for use for cooling and storage of perishable products that are either cold or frozen.
7. The cold storage area should be installed in an area away from direct sunshine, dust and rain.
8. Depending on the maintained cooling temperature, the cold storage unit can be:
- for medium temperatures ranging from -20 to -5°C.
- for low temperatures from -15 to -60°C
9. According to working conditions, the cold storage is available from 5 to 45°C ambient air temperature.
