FILTER DRIERS

What are Filter Driers in HVAC?

In HVAC systems, filter driers, commonly referred to as driers, play a crucial role in eliminating moisture, contaminants, and debris from the refrigerant. This protects the system from potential damage and ensures its efficient functioning.

Filter driers are vital safety devices widely used in air conditioning and refrigeration systems. They primarily facilitate oil filtration from the condenser coils and act as moisture separators, enhancing the cooling efficiency of the entire system while preventing compressor damage or significant breakdowns.

These driers contain desiccant materials that absorb moisture from the refrigerant, preventing the formation of ice and acid that could harm system components. Additionally, they filter out particulate matter like dirt, debris, and metal shavings that can clog or damage the system.

By effectively removing moisture and contaminants, filter driers safeguard critical components such as the compressor and expansion valves, ensuring optimal system operation.

Here are some of the most commonly used filter driers in the HVAC and air conditioning industry:

• Liquid Line Driers: Installed in the liquid line, which transports refrigerant from the condenser to the evaporator.
• Suction Line Driers: Installed in the suction line, carrying refrigerant from the evaporator to the compressor.
