FI22AS is a high-efficiency condenser and evaporator optimized for reversible heat pump systems using environmentally friendly, low global warming potential and natural refrigerants. Utilizing our patented AsyMatrix2 technology, it delivers a high thermal performance while ensuring a low secondary side pressure drop. This design makes it ideal for systems with demanding thermal and hydraulic requirements. The compact channel design minimizes the required refrigerant charge, making it an excellent choice for residential heat pump systems.
