200 Ton Industrial water cooled screw chiller double compressors

As a leading water-cooled screw chiller manufacturer with over 15 years of experience. OUMAL chiller provides a complete range of water-cooled screw chiller from OMC-WDH series.

The cooling capacity of screw water chiller is from 30Ton to 500Ton/105KW to 1750KW and the chiller temperature control range from +30ºC to -40ºC.

Besides the standard water-cooled screw chiller control temperature from 7ºC to 30ºC, OUMAL chiller also has a water-cooled glycol screw chiller control temperature below zero from 0ºC to -40ºC for some special industrial applications.

Using famous brand Semi-hermetic Screw Compressor- Bitzer from Germany and Handbell from Taiwan.

Each screw compressor comes with 4 steps of energy control 0-25%-50%-75%-100% to make sure the whole screw chiller operates when stable with high refrigeration performance.

Each water-cooled screw chiller with high-efficiency shell and tube type heat exchanger and shell and tube condenser.

Integrated PLC control system with human-computer interface and big LED touch screen panel for easy operation.

Other refrigeration parts are world famous refrigeration spare parts like Danfoss or Emerson thermal expansion valve, Alco dryer filter, Schneider contactor, and overload relay will make sure the whole screw chiller works under normal condition.

Compared with air cooled screw chiller, water cooled screw chiller should run together with external cooling tower and water pump. This is the biggest difference between air cooled screw chiller and water cooled screw chiller.

As a professional water cooled screw chiller manufacturer, OUMAL Chiller has exported many water cooled screw chillers to the Philippines, Australia, New Zealand, Malaysia, Singapore, Indonesia, Chile, Mexico, Costa Rica, Brazil, Argentina, Colombia, South Africa, Nigeria, Saudi Arabia, Dubai, Spain, Italy, etc.

If you are searching for a water-cooled screw chiller supplier, you are coming to the right place. Oumal chiller is a high reputation brand in the refrigeration market.

If you have any water-cooled screw chiller inquiry, please contact our engineering for a solution and free quotation.

Water-cooled screw 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.
