3 The decision to use a steel drier or a copper spun type filter drier depends primarily on the application and the size of the system. Copper spun filter driers are commonly used in smaller systems that require less refrigerant load: these systems are less complex, have less pressure fluctuations and a lower level of vibration. Likewise, they are less expensive than their steel counterparts. copper spun filter driers are a reliable component to efficiently control pollutants in systems in operation, absorbing moisture and providing a better filtering. Typical applications include: refrigerators and freezers small commercial refrigeration units air conditioners showcases reach-in coolers FEATURES Application in air conditioning, heat pumps and refrigeration systems Their complete structure made in copper increases corrosion resistance and facilitates the soldering of the equipment 100% high quality molecular sieve beads Pipes are easily cut, stamped, twisted and bended during installation Filter models with an access valve are applicable for systems which originally do not have a service valve on the high pressure side They are pressurized with dry nitrogen to prevent moisture penetration Compatible with refrigerants and lubricants commercially available: CFC, HCFC and HFC Maximum working pressure: 500 Psi NOMENCLATURE K-MSB-(C)-(YY)-(Z)-(A) (A) = With Service Valve (absence: without service valve) (Z) = Connection Terminals (S=Solder; F=Flare; etc.) (YY) = Dimensions (weight in grams) (C) = Copper Spun (MSB) = Molecular Sieve Beads Filter Driers (K) = Manufacturer : T h a n k y o u f o r c h o o s i n g o u r p r o d u c t s Rev

Moisture is one of the most harmful, which is caused by several factors, among them: Refrigerant used, which was previously stored in containers not properly conditioned and not completely dry. Vacuum, essential before charging the refrigerant, is not appropriate or is not kept long enough in the system. Oil used for re-charging the system is often exposed to air humidity. The high temperatures along with humidity generate complex phenomena that increase the formation of acids in both lubricating oil and refrigerant. As these organic acids of the oil react with metal, they form a viscous compound of insoluble metal salt and large molecules of polymerized oil. If this situation is not solved on time, it can affect the proper lubrication of the compressor s moving parts and can block valves and filters.

5 DEHYDRATION OF REFRIGERANTS (Cont.) In the liquid phase, water solubility in the refrigerant is quite reduced, especially at low temperatures. Therefore, when the water in the system exceeds the minimum solubility limits allowed at low temperatures, the excess water becomes ice and blocks partially or completely the expansion valves and capillaries. INSTALLATION When installing a filter drier, it must be vertically positioned with the flow arrow tip pointing down. If installed horizontally, make sure output is angulated downwards to allow our drier to filter all contaminants and ensure a liquid seal at the inlet. It is therefore necessary that refrigerant plants be equipped with a filter drier in the liquid line to prevent these effects. Water absorption combines with the neutralization of the acids, which may be present in the refrigerant and with a strong filtering action.
