OVERVIEW

Built for Efficiency.
Designed for Industry.

Drycool Systems introduces its next-generation Water Cooled Inverter Screw Chiller series featuring advanced inverter-driven screw compressors designed to achieve maximum operational efficiency and energy savings. The system combines an integrated inverter drive with a permanent magnet motor to deliver superior performance, reduced operating costs, and enhanced reliability for industrial and commercial cooling applications. The compressor package incorporates a fully integrated three-stage oil separation system, automatic two-step VI sliders, oil filtration system, integrated check valves, and built-in MODBUS communication capabilities. These advanced features ensure smooth operation, intelligent monitoring, and optimized performance under varying load conditions. Compared to conventional screw compressors, the inverter screw chiller can deliver efficiency improvements ranging from 5% to 70%, particularly during part-load operation where most cooling systems spend the majority of their operating hours. The advanced inverter technology continuously adjusts compressor speed to match cooling demand, significantly reducing energy consumption while maintaining precise temperature control. Designed according to international manufacturing standards, these chillers are available in multiple capacities to accommodate a wide range of cooling requirements. The combination of fixed-speed and inverter compressor configurations provides exceptional flexibility and efficiency, making the system ideal for hospitals, office buildings, hotels, commercial facilities, and industrial process cooling applications where load conditions vary throughout the day and across seasons.

Variable-speed operation automatically adjusts cooling output based on demand, reducing power consumption and operating costs.
Prominent Features
The Water Cooled Inverter Screw Chiller utilizes an externally controlled Variable Frequency Drive (VFD) system that continuously adjusts compressor speed according to actual cooling demand. This intelligent speed modulation significantly improves energy efficiency and system performance under varying load conditions.
The inverter system allows screw compressor operation between 40 Hz and 60 Hz, corresponding to approximately 2200 RPM to 3500 RPM. Advanced inverter control technology further expands operational flexibility by allowing variable-speed operation across a broader performance range, ensuring optimal cooling output and power savings.
Unlike conventional screw chillers that utilize standard motors, the inverter series incorporates high-efficiency permanent magnet motors. This technology significantly improves part-load efficiency, reduces electrical losses, and contributes to substantial long-term energy savings.
The chiller is equipped with advanced software and intelligent monitoring systems that continuously regulate operating parameters, lubrication conditions, and compressor performance. Automated control functions maintain system health and ensure reliable long-term operation.
The compressor package includes a fully integrated three-stage oil separator, automatic two-step VI sliders, oil filter, integrated check valve, and built-in MODBUS communication. This innovative design improves reliability, simplifies maintenance, and enhances overall system performance.
System Advantages

Exceptional Energy Savings

The inverter compressor continuously adjusts its operating speed according to cooling demand, significantly reducing power consumption compared to conventional fixed-speed screw chillers.
