100 Ton screw type compressor water cooled chiller  

Oumal 100 Tons screw compressor water cooled chiller can use single compressor or double compressors. Compressor use Hanbell Brand from Taiwan, Bitzer compressor from Germany optional.

The screw chiller is called the screw compressor. It is mainly composed of screw refrigeration compressors, condensers, evaporators, electronic control components, instruments, etc. Because of its compact structure, small size, and easy It has the advantages of less damaged parts, simple and convenient use and maintenance, stable operation and high reliability. At present, it is widely used in large-scale industrial refrigeration and central air-conditioning systems.

In the screw chiller, according to the screw refrigeration compressor used, it can be divided into single screw compressor and twin screw compressor. According to the connection mode of the motor and screw, it can be divided into open type and closed type. The placement position can be divided into horizontal and vertical.

The working principle of the screw chiller is: when the unit starts to work, the compressor sucks the low-temperature and low-pressure refrigerant in the evaporator into the cylinder. After the compressor works, the refrigerant vapor is compressed into high-temperature and high-pressure gas, which enters the condenser through the exhaust pipe Inside. The high-temperature and high-pressure refrigerant gas exchanges heat with the cooling water in the condenser, and transfers the heat to the cooling water, while the refrigerant gas is condensed into a high-pressure liquid. The high-pressure liquid from the condenser enters the evaporator after being throttled and pressure-reduced by the thermal expansion valve. In the evaporator, the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes, so that the chilled water is cooled down and becomes the required low-temperature water. The vaporized refrigerant gas is sucked in by the compressor again for compression, and discharged into the condenser, so that it goes round and round, and circulates continuously, so as to realize the cooling of the chilled water.

Water-Cooled Screw Chiller Product Information

Oumal Screw compressor chiller advantage

1. We have the complete products lineup from 30ton to 850ton cooling capacity, can meet your wide operating map for both industrial plant cooling and commercial comfort cooling applications.


2. Our water-cooled screw chillers are designed with one or two refrigerant circuits based on your heat load capacity. Two refrigerant circuits design will improve part-load efficiency to save your electricity consumption.


3. Using a top brand semi-hermetic screw compressor, this single main rotor compressor means inherently quieter operation than dual rotor compressors.


4. The condenser using in water-cooled screw chiller with Perfect forced cooling design, enlarge the cooling capacity, improve refrigerating efficiency. High-efficiency warping tube, enlarge heat exchange area, enhance refrigerant disturbed flow of tube, improving heat exchange rate.


5. Dry Type shell and tube evaporator, with a low quantity of refrigerant sealed, has a good performance of oil return, dispensing with the external oil pump or oil return filter. It has no easy damaged parts and has low costs of maintenance. Anymore the outlet and inlet of the refrigerant appear asymmetric in distribution. By utilizing the refrigerant, it increases the efficiency of heat transfer.


6. Our water-cooled screw chillers connected with solid-state starters are standard to provide controlled acceleration and deceleration with less compressor stress and vibration.


7. All water-cooled screw chillers are charged with environment-friendly refrigerant R407c, R-134a, or R410a has no ozone depletion potential and no phase-out schedule.


8. Each water cooled screw chiller equipped with an advanced microcomputer control system. This clear user-friendly LCD touch Console features. 7-inch LCD touch console, visual, simple, intuitive.

The display makes it easy to view the current operating status and simplify the setting procedure. Various parameters can be confirmed at a glance. Regardless of operating status, the console allows you to set a variety of operation modes. A warning log function makes it possible to recall the latest 10 recent warning events.


9. Our water-cooled screw chiller has complete protections including: safety valve, over-high exhaust temperature protection, screw compressor motor temperature protection, high pressure/low-pressure protection, three-section over current protection, oil heater anti-freezing protection.


10. Water-cooled screw chiller with compact size fits through a 3-foot door will lower the owner’s installation costs.


Water-cooled screw chillers can be widely used in plastic, electroplating, electronics, chemical, pharmaceutical, printing, food processing, and other industrial refrigeration processes, or in large shopping malls, hotels, factories, hospitals, and other central air conditioning projects where chilled water is used for centralized cooling.
