ASCW series — Air-cooled screw type water chiller

Industrial water chillers are divided into two types: air-cooled and water-cooled, mainly referring to the different condensers. Technically, water cooling is 300 to 500 kcal/h higher than air cooling; In terms of price, water cooling is much lower than air cooling; In the installation, water cooling needs to be incorporated into the cooling tower before use, and air cooling is mobile without other assistance. However, air cooled water chiller relies on the fan to dissipate heat, which has requirements for the ambient environment: such as ventilation, humidity, air PH value and etc...

    Characteristics

    • World-renowned twin-screw compressor, high efficiency, low noise, less wearing and long service life
    • SIEMENS PLC controller with Chinese/English human-computer interface
    • Perfect breakdown protection:high and low pressure protection, anti-freezing protection, water flow protection, reverse and lack phase protection
    • The chiller uses high efficiency heat exchanger with advanced, unique shape design and systems.
    • The chiller can be installed directly on the roof, or the other outdoor well-ventilated places. 
    • High utilization rate of space with using W shape coil design
    • The unit adapts to outdoor harsh weather conditions and has a good operating results during the life cycle.
    • Maintenance: the chiller is strong anti-corrosion with waterproof control cabinet, not easy to fade and corrosion.

    Configurable options

    • Salt water evaporator
    • Stepless energy adjustment
    • Heat recovery
    • Pump control
    • Special requirement of power supply

    Specification

    • Refrigerant: R22/R134a/R407c
    • Evaporator max water pressure: 1.0MPa
    • Water-side fouling factor of evaporator: 0.018m2°C/kW
    • Allowable voltage fluctuate:±5%
    • Allowable frequency fluctuate: ±2%
