Filter Drier

What is filter-drier air conditioning?

Filter driers are HVAC system equipment that combines the functions of a filter and a dryer (or drier). A filter is used to keep particles like dirt, metal, and chips out of the refrigerant flow control system. A thermostatic expansion valve or a capillary tube might be used to regulate refrigerant flow.

The filter is also known as a strainer in some cases. It’s vital that these particles are filtered away and don’t enter the metering device. It can produce a clog in the refrigerant passage flow in the expansion valve, resulting in faulty system operation.

The term implies that a dryer is used to remove moisture from the refrigerant. It’s also referred to as a dehydrator or a drier. Moisture must be removed from the system; otherwise, it would freeze inside the tube, restricting the flow of refrigerant. When moisture comes into touch with the oil in the system, it creates acids and sludge.

High-capacity filter driers for air conditioning applications

The DMB/DCB bi-flow filter driers at Al Imran guarantee that refrigerant liquid flows from the outside edge of the filter core to the center of the filter drier. In this method, regardless of the flow direction, all dirt particles are kept.

These devices are typically found in larger systems with refrigerant circuits that are intended for field servicing. These devices are not used in residential units that are charged with refrigerant at the manufacture and completely sealed since the risk of moisture and particles entering the system is negligible.

Features and benefits of our filter driers

• Filter driers with bi-flow.
• Ensure that moisture, as well as organic and inorganic acids, are absorbed quickly and effectively.
• By reversing the flow direction, no dirt is discharged.
• The shell of the filter is UL certified for PS/MWP up to 46 bar/667 PSIG
• Solder (CU-plated steel) and flare connectors are available.
