Key Features and Technical Advantages
Proprietary 5/6 Rotor Profile: Utilizes Lynxcool’s self-designed asymmetric screw rotor profile. The 5/6 lobe combination ensures optimal lubrication and smooth meshing, resulting in exceptionally quiet and vibration-free operation of the Semi-hermetic Single-Stage Screw Refrigeration Compressor Unit.
Ultra-Compact Integrated Design: The sleek, space-saving design integrates the suction filter, shut-off valves, and temperature sensors into the main housing, making it ideal for compact machine rooms.
Advanced Motor Protection: Features an intelligent monitoring module that provides comprehensive protection against motor overheating, phase loss, and reverse rotation.
Smart Operational Feedback: Real-time data transmission allows operators to monitor the precise status of the motor and refrigeration system for optimized performance.
Heavy-Duty Multi-Bearing System: Employs a sophisticated multi-bearing arrangement to eliminate axial and radial rotor wear, allowing the unit to handle high loads with low acoustic output.
High-Efficiency Oil Separation: The built-in multi-stage oil separator achieves an industry-leading efficiency of 99.85%, ensuring clean heat exchangers and stable oil return.
Integrated High-Density Filter: A built-in 100μm high-density suction filter protects the internal components and is designed for quick and easy replacement during routine maintenance.
Enhanced Gas Cooling: The internal flow path is engineered to use cold suction gas to cool the motor efficiently before it reaches the screw rotors.
360° Flexible Installation: Suction and discharge shut-off valves can rotate 360°, providing unparalleled flexibility for piping layouts in tight spaces.
Reliable Built-in Safety Valve: Features a high-specification internal relief valve designed to meet the strictest safety standards for long-term reliability.
