Filter plays an important role in cold storage refrigeration system

Filter is an indispensable device on the transmission medium pipeline, usually installed in the pressure reducing valve, pressure relief valve, fixed level valve, square filter other equipment at the entrance of the end equipment. The filter is composed of a cylinder, stainless steel screen, a blowdown part, a transmission device and an electrical control part. After the water to be treated passes through the filter drum of the filter screen, its impurities are blocked. When it needs to be cleaned, as long as the detachable filter drum is taken out, it can be reloaded after treatment. Therefore, it is very convenient to use and maintain.

In the cold storage refrigeration system, the filter is a necessary refrigeration component, used to improve and improve the working conditions of the cold storage, or improve the economy and security of the cold storage. Especially for freon refrigeration system, it is necessary to strictly control the refrigerant water, even a small amount of water is enough to freeze the expansion valve and cause the system ice blocking. Therefore, in order to prevent water from entering the refrigeration system, a filter dryer must be equipped to absorb the water that has entered the system.

Filter in the cold storage is very powerful, not only can remove the water in the liquid or gas, but also can remove solid impurities, because the dryer and the filter is assembled together, so we call the filter dryer. It is a combination of desiccant and filter element in a shell, in the cold storage refrigeration system, filter dryer belongs to the safety protection equipment.
