High Efficiency 300 Ton Water Cooled Chiller Cooling Tower System
1. Adopt the best (semi-hermetic) screw compressor from abroad, 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 emissions，high sealing performance.
2. The human machine interface configures a full touch screen, which enables automatic control and accurate monitoring. the advantages of unit: waterproof，dust-proof, corrosion resistant, long life. Step or steppless capacity control, the unit ensure that it bring into the most energy-saving effective in any load conditions.
3. 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. 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.
5. A full intelligent control system and non-stop running within 24 hours.

FAQ:
1.How to calculate cooling capacity for chillers
Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-t2)/0.86
Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)
2. How to select the model of the chiller ?
It is better to tell us some parameter, such as : Cooling Capacity, Outlet Temperature, Power Supply,Environment Temperature, Application Field, Anti-rust Or Anti-corrosion, and so on.Meanwhile,we could do customized chiller according to your end user consumption.
3.Cooling capacity unit conversion?
1 kcal／h ＝ 1.163W,1 W ＝ 0.8598 kcal／h；
1 Btu／h ＝ 0.2931W,1 W ＝ 3.412 Btu／h；
1 USRT ＝ 3.517 kW,1 kW ＝ 0.28434 USRT；
1 kcal／h ＝ 3.968 Btu／h,1 Btu／h ＝
