R134a Series Screw Chiller 340kW - 2100kW Industrial-Grade Cooling Solution

The R134a Series Screw Chiller represents decades of expertise in large-capacity cooling solutions. Featuring industrial-grade semi-hermetic twin-screw compressors and high-efficiency flooded shell-and-tube heat exchangers, this series delivers reliable performance for medium to large commercial, industrial, and process cooling applications.

With cooling capacities ranging from 340kW to 2100kW, the R134a series offers versatile configurations including heat recovery units, ice storage systems, high-temperature water units, and large temperature differential models to meet diverse customer requirements.

The advanced oil management system with triple-stage oil separation ensures stable operation under all load conditions, while the precision capacity control system enables stepless modulation from 25% to 100% for optimal energy efficiency.

Features & Benefits

Industrial-Grade Screw Compressor - Semi-hermetic design reduces refrigerant leakage; 5-tooth/6-tooth asymmetric rotor profile with micron-level precision; Swedish SKF bearings ensure 50,000+ hours MTBF.
High-Efficiency Flooded Evaporator - Optimized refrigerant distribution with enhanced temperature field; liquid separator prevents compressor suction with liquid, improving reliability.
Advanced Condenser Design - Twisted-fin tube technology increases heat transfer coefficient; dual water circuit design with straight-through cleaning capability.
Triple-Stage Oil Separation System - In-compressor + condenser + dual ensures minimal oil carryover and reliable lubrication.
Stepless Capacity Control - 25%-100% stepless modulation precisely matches cooling output to load; advanced electronic expansion valve ensures rapid response.
Eco-Friendly R134a Refrigerant - Zero ozone depletion potential; optional R513A for even lower global warming potential; high thermal efficiency.
Low Noise Operation - Built-in compressor muffler; vibration-damping mountings reduce mechanical noise transmission.
Intelligent Control System - 7-inch touch screen with RS485/Modbus interface; 20+ protection functions; remote monitoring capability via iBUILDING platform.
