The Free Cooling System option (sometimes referred to as “integrated water-side economizer” in the industry) adds a fluid-to-air heat exchanger coil in series with the chiller refrigerant condenser coil. The heat rejection airflow moves across both coils, allowing heat rejection and chilled fluid cooling without the need for vapor compression when outdoor air temperatures are lower than the cooling fluid temperature. Withair’s Free Cooling System solution that combines the benefits of an integrated water-side economizer with Variable Frequency Drive (VFD) compression technology and total unit configurability, using a VFD to meet partial load demands and varying outdoor ambient conditions at optimized efficiency levels, offering solutions fully tailored to the application requirement.
Our Withair® 20Ton and 40Ton Industrial Use air-cooled scroll chillers deliver top-of-the-line, full-load efficiency for assurance of performance in the most demanding conditions. But you can also count on excellent performance during 99% of the time when chillers operate at off-design conditions.
