Central Chiller Air Cooled Screw Type Bitzer Compressor


Central Chiller is a chiller which can provide cooling water for several Processes. It can be Air cooled type chiller or water cooled type chiller, It can be screw type chiller or scroll type chiller. Central Chiller Air Cooled Screw Type Bitzer Compressor is a type of High efficient Air Cooled Chiller. Compare with the Air Cooled Scroll Type Chiller, its Cooling Capacity range is large. The Compressor is semi-hermetic screw type. The Screw Compressor Features are below: 

(1) All rolling bearings are used
The radial bearings use cylindrical bearings, and the thrust bearings use ball thrust bearings to withstand the axial thrust of the rotor. The clearance of these rolling bearings is smaller than that of the sliding bearings, which can keep the rotor shaft stable, thereby reducing the rotor clearance and reducing leakage losses.
(2) Differential pressure oil supply
The difference between the exhaust pressure and the pressure at the bearing is used to supply oil, and no oil pump is provided, which simplifies the lubrication oil supply system.
(3) There is an oil mist eliminator inside the machine
The inhaled gas first passes through the motor, cools the motor, and enters the cylinder to be compressed and discharged. An oil mist eliminator is installed in the exhaust cylinder to separate the oil droplets from the gas. Therefore, there is no need to install an oil separator in the system. The unit device structure compact.
(4) Stepless adjustment of air delivery
The stepless adjustment of the compressor air volume by means of a movable slide valve is better than the stepwise refrigeration capacity adjustment of a reciprocating compressor.
(5) Spray cooling
When the exhaust temperature of the semi-hermetic screw compressor is high, the lubricating oil temperature rises too high, and the compressor motor is often easily burned. For this reason, the injection liquid refrigeration method can be used to cool down to ensure that its working condition is in the compressor. The scope of work limits.

Air Cooled Central Chiller Products Information


Features:
1. The compressor adopts the international brand. The original imported international brand BITZER Germany (Bitzer) , a new type of high-efficiency screw rotor compressor, the efficiency is 20%-30% higher than the general compressor.
2. High efficiency 5:6 patented asymmetric rotor tooth profile.
3. Capacity control can adopt four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and stepless control system.
4. The combined design of 11 bearings and a-type axial thrust balance drum greatly increases the bearing life by 2.5-3.5 times.
5. The use of high-efficiency silicon steel sheet special groove design, and equipped with internal and external omnidirectional design cooling channel, so that the compressor motor can play the highest efficiency under any load.
6. The unique built-in oil pressure system does not need an oil pump to ensure that the compressor maintains the best lubrication effect. The oil separator adopts a double-layer filter method, which has a good oil filtering effect and the heat exchanger can exert its maximum capacity.
7. High efficiency, low noise and low vibration.
8. A variety of refrigerants are available. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c can also be used.
