SCMI164MM - GMC 1/2'' x 1/2'' 250 cm³ FILTER DRIER
MOLECULAR SIEVE WITH LIQUID AND MOISTURE INDICATOR
Function:
The function of an indicator filter is to protect the system from moisture, acids, and solid contaminants; this filter should be installed on the liquid line. The presence of moisture, immediately indicated by the associated indicator, can cause ice formation; under normal system load and operating conditions, the refrigerant must pass through the indicator in a completely liquid state. The presence of bubbles indicates partial evaporation of the fluid along the liquid line.
Construction:
All indicator filter models have a body and head made of UNI EN 10130 – DC04 steel. The two parts are assembled by MIG welding. In this type of filter, the desiccant charge consists of a single, compact block made of 100% 3 Å molecular sieve. This cartridge is coupled with a special type of felt that allows effective mechanical filtration combined with low resistance to fluid movement, benefiting dehydration efficiency. The presence of the indicator downstream of the filter instantly guarantees the actual efficiency of the filter. The indicator is characterized by a moisture-sensitive element whose color changes from green to yellow in the presence of moisture; in the factory, the yellow color indicates that it is time to intervene to replace the dryer filter. The production range includes versions with SAE Flare threaded connections and copper-plated steel weld connections.
Installation:
To optimize filter performance, it is recommended to mount it with the longitudinal axis vertical and the arrow pointing downwards. The importance of filters within the system is such that scheduled maintenance is recommended to check its efficiency and thus ensure the proper functioning of the system.
