Air dehumidifying filters (or dryers) are used for air conditioning, heat pumps and refrigeration systems.
The range of uses is therefore diverse, from industrial plants to automotive and road transport.
The dryers, in a refrigerant system, are mounted before the expansion valve and are crossed by the refrigerant (liquid state) to dehumidify and purify it. In this way, the expansion valve does not stop and the system avoids deterioration due to the formation of acids.
