Water-cooled screw variable frequency chiller unit

Our newly launched water-cooled screw variable frequency chiller unit is an efficient industrial-grade variable frequency system. It not only inherits the quality of the original fixed-speed model but also incorporates advanced variable frequency technology. Equipped with a renowned brand variable frequency inverter, it significantly enhances energy efficiency during part-load operation. This dual-efficient screw unit boasts high full-load energy efficiency (COP) and integrated part-load performance coefficient (IPLV). The outlet water temperature control accuracy is within ±0.5 degrees, making it widely applicable in process water temperature control fields, enhancing product quality and meeting high-precision water temperature requirements.
Key Features of the Cold Water Chiller with Variable Frequency Screw Compressor
High-efficiency energy-saving
Utilizing the latest airborne variable frequency drive technology, the partial load energy efficiency of the unit is significantly improved, with the highest integrated partial load performance coefficient (IPLV) reaching around 10.
Stable and reliable
Single compressor structure, fewer moving parts, compressor rotor directly connected to the motor, reducing the operating components and further enhancing the reliability of the compressor; refrigerant absorbs and cools the motor, resulting in lower operating temperatures and greater stability.
Easy to install
The water-cooled screw chiller with variable frequency starts from the integrated control cabinet, simplifying on-site wiring for users; pre-filled with refrigerant and lubricating oil before shipment, facilitating installation and saving users' installation and commissioning costs.
Variable Frequency Advantages
Variable frequency water-cooled screw chiller with soft start to reduce the impact of starting current; includes a built-in DC reactor to lower harmonic interference; optional low harmonic filter available, meeting IEEE-519 specifications for harmonic distortion under inverter input power, with features such as overtemperature protection for the harmonic filter and capacitor switching function.
Environmentally friendly
The water-cooled screw variable frequency chiller can be equipped with refrigerants as per requirements, causing no damage to the Earth's ozone layer and complying with the requirements of the "Montreal Protocol"; its unique film evaporator design can reduce the amount of refrigerant injected.
Control advanced
Next-generation Siemens PLC controller, precise control of the unit, ensuring rational operation, paired with remote monitoring interface, dynamic color touch screen, graphical operation, enhancing user experience.
◆ Precise Temperature Control
The precision of the frozen water outlet temperature control is within ±0.5 degrees, meeting the high-precision temperature control requirements.
