Filter Driers

Filter driers are critical components in refrigeration and air conditioning systems. They serve a dual function—filtering out solid contaminants and removing moisture from the refrigerant circuit. By maintaining system cleanliness and dryness, the driers prevent corrosion, acid formation, and blockages that can damage compressors, valves, and other components. They are essential for both new installations and maintenance of existing systems.

At Finstar Industrial Systems Ltd, we supply a wide range of high-performance filter driers suitable for various refrigerants including R134a, R404a, R410a, and R32. Our stock includes both liquid line and suction line driers, available in multiple sizes and connection types (flare and solder). Each unit is factory-sealed for maximum moisture control and compatibility with modern synthetic oils and refrigerants.

Applications of filter driers

Cold Rooms and Freezer Systems
Filter driers protect cold room systems by eliminating moisture and debris from refrigerant lines. This ensures smooth system performance and prevents expansion valve blockage and compressor wear.
Supermarket Display Refrigeration
In multi-unit display cases, driers safeguard the entire system by maintaining clean and dry refrigerant flow. They help reduce service intervals and extend the life of capillary tubes and TXVs.
Split and Central Air Conditioning Systems
In HVAC systems, filter driers remove residual moisture after installation or servicing. This prevents the formation of acid and protects key components from corrosion and failure.
Refrigerated Transport Units
Mobile refrigeration units are prone to vibration and contamination. Installing durable driers ensures the system remains sealed, dry, and stable during transport operations.
Chillers and Industrial Cooling Systems
In chillers, even small amounts of moisture can cause freeze-ups or acid build-up. These driers keep the refrigerant clean and stable, maintaining optimal heat exchange efficiency and system longevity.
