Cooled Screw Water Chiller, 120, 150, 450

120 Ton 150 HP 450 Kw Box Type Air Cooled Screw Water Chiller

Anyda as the china water chiller manufacturer, have gradually produced Industrial Chiller,Water Chiller,Screw Chiller,Air Cooler,Oil Chiller,Low Temperature Chillers,Hot Water Chiller, Heat Pumps and Central Air Conditioner which are widely applied to plastic & rubber machinery, daily-use chemical, textile, general machinery, laser machinery, LCD and PCB industry, electroplating, equipments of laboratory, food, pharmacy, etc .

Main Features

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.

1.How does a chiller system work?

   Chiller has two circulation,one is process water circulation,the other is refrigerant gas circulation.Heat picked up from the process.Heat transfers to refrigerant circulation.Heat is remove to air or water.

2.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)

3.Types of chiller system?

   Air Cooled Chiller and Water Cooled Chiller.Water cooled chiller needs a separated cooling tower and has a higher efficiency,but less easier than air cooled.

4.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 ＝ 0.252 kcal／h； 

1 USRT ＝ 3024 kcal／h,10000 kcal／h ＝ 3.3069 USRT； 

5.This chiller could do heat recovery?

    Yes,please kindly send us the temp and water volume per hour.

6.Chiller maintenance?

Step 1: Keep Tubes Clean
Step 2: Ensure a Leak-free Unit
Step 3: Sustain Proper Water Treatment(prevent scale, corrosion)
Step 4: Analyze Oil and Refrigerant
