Product Features and Advantages
High-Efficiency Screw Compressor
This chiller unit employs an industrial third-generation 5-to-6 tooth asymmetric design screw compressor, with direct motor drive to reduce wear. Yin and yang rotors are processed with high precision for high volumetric efficiency and low noise. Specialized design for full-liquid evaporation enhances compression efficiency. The motor is cooled by low-temperature refrigerant for heat dissipation and leak prevention. A built-in high-efficiency oil separator eliminates the need for an oil pump, and unloading/voltage reduction startup minimizes grid impact.
Precise Refrigerant Control
Advanced control logic and an electronic expansion valve automatically adjust refrigerant flow based on load, optimizing energy efficiency. Zero-process control enables rapid adjustments, ensuring evaporator stability. Unloaded operation increases heat exchange area utilization, improving part-load efficiency.
Superior Oil Treatment System
Low oil level protection prevents compressor oil shortage. Combined mechanical and adsorption separation thoroughly separates oil. High-pressure liquid injection return technology eliminates oil film resistance on heat transfer tubes, ensuring reliable oil return.
Patented Rotor Design
5/6 asymmetric rotors balance radial forces. Patented tooth profiles provide good lubrication, reducing noise and improving efficiency. High exhaust frequency reduces airflow pulsation, minimizing vibration and noise.
High-Efficiency Full-Liquid Evaporator
New heat exchange mode increases evaporation temperature, with a total heat transfer coefficient more than three times that of traditional evaporators. Specialized structure forms stable vapor cores, improving heat transfer efficiency. Optimized refrigerant distribution reduces pressure drop. Enhanced heat transfer ribs delay scaling. Near-saturated suction improves compression efficiency. Chilled water flows inside the tubes, simplifying scale cleaning. High-quality shell with anti-rust treatment.
Standard Unit Features
Multi-compressor structure improves part-load performance and reduces startup current. Expansion valve throttling enhances unit efficiency. Chinese touchscreen control provides convenient operation. Optional PLC control offers various protection functions.
Comprehensive System Protection
Includes multiple protection functions: low suction pressure, high exhaust pressure/temperature, motor overheating, phase sequence protection, low oil level, oil pressure differential, water flow, preheating, and water temperature.
Environmentally Friendly R134a Refrigerant
Uses R134a refrigerant with an ODP of 0, operating at lower pressures than R22, extending lifespan and preventing lubricant carbonization. Energy efficiency is higher than R22 units.
Intelligent Electrical Control
Precise controller and user-friendly interface provide status display, parameter setting, and fault diagnosis. Real-time monitoring of operating parameters and automatic equalization of operating time. Multiple protection functions ensure safety. Supports independent operation or networking for complex control.
Simplified Installation and Maintenance
Features complete safety functions and fault self-diagnosis. Can operate in parallel or individually, with high efficiency at partial loads. Pre-charged with refrigerant and lubricant, and pre-insulated, reducing on-site installation and debugging time.
