Pressure controller is mainly used in the refrigeration system as a kind of control device to protect the system from too higher or lower pressure or it can be used for refrigeration units to control the cooling system start and stop through the system pressure. It also can be used for other industry fields which need control the pressure such as steam iron and reservoir, etc.
