Everwell® BI-FLOW HEAT PUMP - LIQUID LINE FILTER DRIER

A Everwell® BI-FLOW HEAT PUMP - LIQUID LINE FILTER DRIER is a specialized filter component used in heat pump systems that allows refrigerant to flow through it in either direction, effectively filtering out moisture and contaminants regardless of the flow direction, making it ideal for the reversing cycle of a heat pump operation; essentially, it can filter the refrigerant whether the system is cooling or heating. 

Used in liquid lines:
This type of filter drier is installed in the liquid line of a heat pump system, where the refrigerant is primarily in a liquid state. 

Benefits:
By effectively filtering in both directions, a bi-flow filter drier can simplify system design and reduce the need for additional check valves. 

Features:

• Designed with internal check valve for dual direction flow and filtration

Unlike standard filter driers, a bi-flow design has internal mechanisms that ensure proper filtration even when the refrigerant flow reverses direction, which happens in a heat pump system when switching between cooling and heating modes. 

• Solid copper fittings
• High acid and moisture removal

The filter drier contains a desiccant material that absorbs moisture and acidic contaminants from the refrigerant, protecting the system components.

• Corrosion resistant epoxy powder paint
• Max. working pressure: 680 psi, 4700 KPA
