Water dispenser filter drier

The refrigerant filter in the cooling system of a water dispenser is designed to be installed before the capillary tube. It protects the capillary tube from clogging caused by solid particles present in the refrigerant (freon), absorbs moisture contained in the refrigerant to prevent ice formation and system blockage, and ensures reliable and stable operation of the cooling circuit, thereby extending the service life of the compressor and other components.
