What is a suction drier?

A suction drier is a device used in refrigeration and air conditioning systems to remove moisture and contaminants from refrigerants. It typically contains a desiccant material that absorbs water and filters out impurities, ensuring the refrigerant remains clean and effective. This helps to prevent corrosion and damage to the system's components, enhancing overall efficiency and longevity. Suction driers are usually installed in the suction line of a refrigeration cycle.
