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.
Withair® Water-cooled Chiller Solutions help meet your building efficiency needs with the widest variety of water-cooled industrial and commercial chillers on the market. From reducing your facility’s carbon footprint, to cutting operating costs, our energy-efficient chillers are tailored to fit almost any application. Building requirements are constantly evolving. To keep you ahead of the curve, we has developed numerous technological innovations for our Withair® chillers. When some refrigerants were identified as ozone depleters, we adapted our chillers to use compounds that are friendly to the environment. When electricity prices began to escalate, we developed enhanced tubes and variablespeed drives that slashed energy use. And when the industry was looking for ways to recover energy, we developed a full line of heat-recovery chillers.
Prices of such commodities have surged by more than 50 percent globally over the past 12 months, creating unforeseen challenges for enterprises the world over, including those in China. Chinese companies across industries are leaving no stone unturned to remain competitive in a tough global market environment.
The Withair® Compact Series chillers are the ideal solution for businesses looking to maximize space and operate at a wide range of nominal tonnages. The Withair® water cooled modular chiller provides reliable performance and optimized capacity from a compact, modular unit with an overall footprint that is 36 percent smaller than similar products. Operate one chiller or integrate multiple units to get exactly the capacity you need for adequate cooling or to establish chiller redundancy. The Withair® water-cooled chillers are complete, factory assembled units designed for a wide range of comfort and process cooling applications, but also have the ability to be piped into a multi-stage array of up to eight (8) chillers for much larger capacities.
