200 ton Air cooled Screw Type Central Chiller System

An industrial central chiller is a piece of equipment used to provide cooling for multiple processes. The chiller incorporates both the refrigeration circuit and controls and is installed in conjunction with a pumping system. Central chiller refers to any chiller unit or chiller system that can cool several processes throughout a plant at the same time. The capacity of these systems can range from 10 to 250 + tons.

Oumal Chiller is a professional central chiller manufacturer and supplier with rich experience, We have a full range of central chillers including air-cooled central chiller and water-cooled central chiller.

 OUMAL air cooled screw type central chiller adopts branded screw type compressor with low noise & vibration, which provides superior performance while lowering energy consumption and dramatically reducing noise levels. High efficient copper condenser and evaporator are made with fined copper tube for heat exchange. Also famous control components ensure stability, durability and reliability. OUMAL   air cooled screw chiller systems comes with Eco-friendly R- 407c refrigerant able to delivery excellent performance at high ambient temperature condition. In a word, OUMAL  air cooled screw chiller unit features  high cooling capacity from 30 Ton to 500 Ton , but these air screw chillers comes with compact size, easy operation and maintenance.

Air Cooled Central Chiller Products Information

1. The compressor adopts the international brand. The original imported international brand BITZER Germany (Bitzer) HANBELL China Taiwan (Hanbell), 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.
