Performance Characteristic 
 

★  The water-cooled screw chiller adopts Taiwan's "Hanzhong" twin-screw compressor, refrigeration accessories such as Danfoss and Emerson, with high overall efficiency, stable performance, and long service life. The touch screen and PLC control system accurately control the energy regulation of the compressor, which can timely and accurately control the matching between the cooling capacity and heat load of the unit, ensuring the unit operates with high efficiency and reducing operating costs. Full Chinese operation interface, menu style prompts, and the ability to freely set the operating status of the unit; The built-in hydraulic system ensures that the compressor maintains its lubrication effect. Efficient internally threaded copper tube enhances heat transfer efficiency and saves energy; The U-shaped heat exchange tube bundle facilitates maintenance and prevents refrigerant leakage; High efficiency, low noise, and low vibration.

★  Customizable variable frequency precision screw chiller, with a temperature control accuracy of ± 0.5 ℃ for chilled water. Accurate temperature control meets the chilled water requirements of precision equipment and saves energy by more than 15-20%.

 Technical description 
 

1. Selection Description: DC-RC50W "DC" is the company code of Duoku. "RC" represents screw chiller, "50" represents horsepower 50, "W" represents water-cooled, and "BP" represents variable frequency.
2. The cooling capacity parameters are based on: chilled water inlet and outlet temperatures of 12 ℃/7 ℃, and cooling inlet and outlet air temperatures of 30 ℃/35 ℃.
3. Scope of work: The temperature range of the chilled water is 7 ℃ to 25 ℃, and the temperature difference between the inlet and outlet of the chilled water is 3 ℃ to 8 ℃. The operating environment temperature cannot exceed 40 ℃, and high-temperature models should be selected if the ambient temperature is higher than 40 ℃.
4. Our company reserves the right to change the above parameters or dimensions without prior notice.
