High efficient water cooled industrial screw chillers

Water-cooled screw chiller features large cooling capacity is an energy efficiency water-cooled chiller for both industrial cooling and commercial cooling applications.


OUMAL is a professional water cooled screw chiller manufacturer and supplier for over 15 years of rich experience.

If you can’t stand the noise-making for air-cooled screw chiller, then water cooled screw chiller is your good choice.

The water-cooled screw chiller manufactured from Oumal provide the ideal water cooling solution for sound-sensitive environments.


Designed with a single main rotor compressor which is inherently quieter than twin screw compressor designs, these screw-type water chillers provide some of the lowest sound levels in the industry.


Water-cooled screw chiller can eliminate the need for expensive sound attenuation equipment and save money for the facility owners.

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.
