800 kw Air Cooled Twin Screw Compressor Water Chiller Description
1.Packaged box type air cooled screw water chiller unit adopt the semi-hermetic screw compressor(like Habell,Bitzer), 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.
2.Packaged box type air cooled screw water chiller unit 's human machine interface configures a full touch screen, which enables automatic control and accurate monitoring. The advantages of unit: water-proof,dust-proof, 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.
3.Packaged box type air cooled screw water chiller unit 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.
4.Packaged box type air cooled screw water chiller unit 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.
