  • A Green Commercial Heating Product - Ultra-high Temperature Water Source Heat Pumps
    Offer a comprehensive solution to the USER ! Withair’s Ultra-high Temperature Water Source Heat Pump can produce high-temperature hot water at 55~122°C while cooling, and realize the dual-temperature and double-effect application of waste heat recovery. One set of ultra-high temperature heat pump equipment is used to replace the traditional two sets.
  • Withair® Air-cooled Chillers with Free Cooling System (Integrated Water-side Economizer)
    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.
