The original ADWIS just got greater, achieved through key design to value activities without compromising its robustness. The ADWIS unit is still a breakthrough in compactness with high drying efficiency and performance. It combines a refrigerant-to-air heat exchanger and an air-to-air heat recovery unit sandwiched by an integrated separator in a modular design. This cost-effective solution offers stable pressure drop, convenient drainage and simple installation. It is proven for new medium and high-pressure refrigerants.
