Aqua-Air – Alpha Chiller – Chilled Water

The Aqua-Air  Alpha Chiller – Chilled Water Chiller Module is the largest selling chiller in the megayacht industry today. Over the last decade, more Alpha’s have been installed in yachts than all other brands combined. Since its introduction in 1993, it has constantly evolved

The chiller removes heat from the water loop that circulates around the vessel, which is used as a refrigerant to remove heat from the cabins and living areas. The chilled water circulates through a chilled water loop and through coils located in air handlers. Chilled water systems include other HVAC equipment designed to exchange heat such as computer room air conditioners.  It then returns to the chiller where the chiller removes the heat from the water using the refrigeration process and transfers the heat into the sea water

Aqua-Air  Alpha Chillers shipped today feature stainless steel chassis’ and fasteners, scroll compressors and Awlgrip coatings. What has not changed is the compactness and unrivalled reliability. In recent comparisons to other brands, the Alpha was on an average 22% lighter and 38% smaller in volume. This means major weight and space savings when the units are racked. Alpha’s are built in capacities from 24,000 to 120,000 BTU/hr and all share the same chassis dimensions

Should a vessels British Thermal Unit (BTU) requirements exceed 120,000 BTU/hr, multiple chillers can be racked together for a larger total capacity
