Introduction
Refrigerants mainly consist of chloride and fluoride of containing hydrocarbons, refrigeration principle is that refrigerant quickly spread. In the process of its diffusion, some of water leakage and freeze in diffuser valve and block system, at the same time, the refrigerant hydrolysis to generate the corrosive gas such as hydrogen chloride and fluoride, the corrosive gas can cause refrigerant leakage, pipeline corrosion and shorten the service life of the refrigeration system. Refrigerant desiccant can effectively absorb water, avoiding freezing, preventing freezing blocking system and corrosion.
Yuanying refrigerant desiccants don't affect the chemical stability of the refrigerant, and can adsorb organic acid and inorganic acid in refrigeration system. It has low dew point, high strength, low abrasion, strong water absorbing capacity, etc.
XH-5: for dehydration and drying of R12, R22
XH-7: for dehydration and drying of new R-134a in household and commercial refrigerators iceboxes and air conditioners
XH-9: for drying all kinds of refrigerants (except mixed refrigerant of containing difluoromethane), for example, refrigerants in refrigerators, freezers, air conditioners, and other refrigeration heat exchange device, is a kind of universal refrigerant desiccant;
XH-11: for dehydration and drying of R404a, R404b, R407c, R410a, R507
