Molecular sieve products are characterized by a high moisture adsorption capacity per volume to make optimal use of available container space in your filter system. In addition, the products exhibit superior attrition resistance and high strength, even after being loaded with moisture. All our products have been extensively tested in a great variety of traditional and new refrigerants and refrigeration oils. It can provide wide-ranging compatibility with refrigerants, and it's a universal desiccant which can be suitable to lots of refrigerants, such as R-12, R-22, R-124, R-125, R-143a, R-152, R410a and R407c, as well as their blends and the corresponding lubricants.
JLRD-7 MS is used to dry the moisture in the refrigerant of R-134a, which is used in the domestic and industrial refrigerator/ air-condition. We can also use JLRD-7 MS to dry the moisture in the refrigerant of butane.
JLRD-9 MS is used to dry the moisture in the refrigerant, which is used in the air-condition/refrigerator of car, estate car, refrigerator car, engine, ship and so on.
JLRD-11 MS is used to dry the moisture in the refrigerant of R407c, which is used in the air-condition.
