Product Description
The RuiDong falling film water-cooled screw chiller is an innovative and energy-efficient product developed and sold exclusively by RuiDong Group Co., Ltd. This chiller is designed to deliver superior performance and energy savings. Compared to traditional dry water-cooled screw chillers, it can save over 18% energy, and compared to flooded water-cooled screw chillers, it can save over 8% energy.
The key features of this chiller include a falling film evaporator, an integrated high-efficiency oil separator, an electronic expansion valve, and an advanced control system. These components work together to enhance the heat exchange efficiency of the refrigerant evaporator and reduce the temperature difference between the evaporation temperature and water. As a result, the unit operates with remarkable stability, efficiency, and energy savings.

Product Details
|Product Advantages
01 High efficiency and energy saving
With its high efficiency and energy-saving features, this technology can save more than 18% energy compared to traditional dry evaporators and more than 8% energy compared to flooded evaporators. This not only greatly reduces energy consumption but also cuts down on operating costs for customers.
02 Stable operation
The technology ensures stable operation through its use of a high-efficiency special spray falling film compressor. This compressor, equipped with twin-screw technology, runs smoothly with low noise levels and has a long service life.
03 Green environmental protection
This technology is environmentally friendly as it utilizes a small refrigerant charge. By using a spray falling film evaporator, the liquid refrigerant is sprayed onto copper tubes to form a thin refrigerant film, which leads to efficient evaporation. Compared to full liquid evaporators, this system can reduce refrigerant charge volume by 50%, resulting in both economic and environmental benefits.
04 High-efficiency oil separation technology
The technology features high-efficiency oil separation techniques, achieving a 99.99% oil separation effect. The exhaust jet impact and interception oil separation technology allows lubricating oil to return normally to the compressor, ensuring proper oil supply without interfering with the oil film on the heat exchanger.
05 Complete protection system
With a complete protection system in place, this technology offers efficient oil separation, advanced control, ejector pump return flow, and comprehensive electrical control system protection. It also includes safeguards for water flow, antifreeze, undervoltage, and phase sequence protection. These features greatly enhance the stability and safety of the unit's operation.
06 Advanced control technology
Advanced control technology is incorporated into this system, including the latest Siemens PLC programmable touch screen control. It also supports remote control and operation through computers, mobile phones, and network communication. These features greatly enhance the user's ability to operate the unit professionally, reducing the risk of misoperation and improving the overall user experience.
