What is a bi-flow filter drier?

A bi-flow filter drier is a component used in refrigeration and air conditioning systems to remove moisture and contaminants from the refrigerant while allowing flow in both directions. This type of filter drier is essential for heat pump systems, where the direction of refrigerant flow can change depending on the heating or cooling cycle. It typically combines a filter element with desiccant materials to absorb moisture and capture debris, ensuring system efficiency and longevity.
