Comparing with traditional air cooled chiller, water cooled chiller system doesn't need a fan to cool the condenser, reducing noise and the heat emission to the operating space, which is more green energy-saving. CW-5300ANSW recirculating water chiller uses external circulating water working with the internal system for efficient refrigeration, smaller size with large cooling capacity with precise PID temperature control of ±0.3°C and less space occupation. It can satisfy the cooling applications like medical instruments and semiconductor laser processing machines that are operating in enclosed environment such as dust-free workshop, laboratory, etc.
