Main Features Screw Chiller's human machine interface configures a full touch screen, which enables automatic control and accurate monitoring. The advantages of unit: waterproofdustproof, corrosion resistant, long life. Step or stepless capacity control, the unit ensure that it bring into the most energy-saving effective in any load conditions. Screw Chiller due to use heat copper tube and high efficiency compressor with high effective thermal expansion current-saving device, the unit will operate in stability, longer and effectively. Screw Chiller adopts a reliable safety protection device: to prevent compressor starting frequently, over-current protection, overheat of motor protection, prevent freezing, sight glass in liquid, oil heating protection, phase protection, HV/LV protection, discharge high-temperature protection, safety value, soluble clock, water shut-off protection, and so on. Work Principle Z50 Series Solenoid Valve,Solenoid Control Valve,Hydraulic Solenoid Control Valve,Solenoid Control Valves Huaian Hy-waloil Machinery Co.,Ltd , https://www.hywaloil.com
Explosion -proof screw Chiller adopt the best (semi-hermetic) screw compressor with explosion-proof feature , and operate credibility, high efficiency, easy to maintain, exact volume control, a wide range of application. The system adopts the latest asymmetric rotor profile. Build-in pressure drop lubricant to system with low vibrations, sound emissionshigh sealing performance.

Note
1. The above red font parameters for special voltage model need to special order; Cooling capacity of R407C unit will be 5% lower than R22 unit
2. Nominal cooling capacity calculated according to: inlet/outlet chilled fluid temperature: 17ºC/12ºC; inlet/outlet cooling water temperature: 30ºC/35ºC
3. Working condition: The temperature range of chilled fluid is from 5ºC to 35ºC; temperature difference between inlet and outlet chilled fluid is from 3ºC to 8ºC.
4. The temperature range of cooling water is from 18ºC to 37ºC; temperature difference between inlet and outlet cooling water is from 3.5ºC to 10ºC.
5. The power distribution and wiring of the installation shall be based on the nameplate or installation instructions of the unit. We reserve the rihgt to modify the above information whithout prior notice
