Product Description Product DescriptionRUIDONG Water-Cooled Screw Chillers (200 kW -3000 kW)1. High-Efficiency Twin-Screw Compressor ? Semi-hermetic, dual-rotor design with only ? the moving parts of a piston compressor → far fewer wear items, lower vibration and noise. ? Stepless capacity modulation 25 %-100 % (or VSD option) tracks building load exactly, cutting annual energy use by 20-35 %. ? Proven stable against liquid slugging, ensuring reliable operation in variable load conditions.2. Advanced Heat-Exchange Technology ? Shell-and-tube evaporator & condenser built to JB/T 4750-2003 pressure-vessel code. ? Internally-grooved DAC copper tubes increase heat-transfer coefficient and reduce refrigerant charge. ? Refrigerant distributor equalizes flow across all tubes, raising evaporator effectiveness by ~8 %. ? Optional total or partial heat-recovery condensers provide free hot water up to 50 °C.3. Robust Protection & Safety Package (10-point) High/low pressure, anti-freeze, phase-reversal, motor over-temperature, over-current, safety valve, check valve, emergency stop, automatic restart after power failure.4. Intelligent Touch-Screen Control ? Micro-computer controller works from -15 °C to 65 °C ambient. ? RS-232 / RS-485 and Modbus-ready for BMS integration. ? Password-protected set-points, run-time logging, predictive-maintenance alerts.5. Customization & Service Support ? 380 V/3 ph/50 Hz standard; 415 V, 460 V, 60 Hz or other supplies on request. ? Refrigerant choices: R-134a (standard), R-513A, R-407C. ? Factory run-test report provided; 1.5-year warranty on major components; global spare-parts network.Ruidong's water-cooled screw chillers deliver higher efficiency, lower maintenance, quieter operation and precise load matching, making them ideal for hospitals, data centers, process plants and district-cooling projects.
