Refrigeration Equipment Water Cooled Cooling System Microcomputer Flooded Screw Type Water Chiller

Product Description

Product Description

 The Water-Cooled Screw Chiller series delivers reliable, energy-efficient cooling for a wide range of industrial and commercial applications. Designed with advanced semi-hermetic screw compressor technology (5:6 asymmetric rotor profile), these units offer 20–30% higher efficiency than conventional compressors. Available in standard temperature (outlet up to +5°C) and low-temperature versions (outlet down to -30°C, with special models to -45°C), the water-cooled screw chiller is the ideal solution for plastics, chemicals, pharmaceuticals, food processing, HVAC, and many other industries.

 All units feature PLC automatic control with a large color LCD touch screen, multi-stage or stepless capacity control, and comprehensive safety protections. Modular design allows flexible configuration, and dual-compressor models provide automatic switching for balanced wear and enhanced reliability.

CORE SELLING POINTS

·High-Efficiency Compressor: Imported high-quality semi-hermetic screw compressor with 5:6 asymmetric rotor profile – 20–30% higher energy efficiency than conventional compressors. Low vibration and low noise.

·Precise Capacity Control: Standard units offer 4-step capacity control (100%-75%-50%-25% or 0-33%-66%-100%); optional stepless (non-stage) control available for applications requiring extreme temperature precision.

·User-Friendly PLC Controller: PLC automatic control with large color LCD touch screen. Full Chinese/English human-machine interface, real-time operating status display, fault self-diagnosis, and last 10 fault records with troubleshooting prompts.

·Comprehensive Safety Protection: Equipped with overload, phase reversal, high/low pressure safety valve, low water flow, low oil pressure difference, low oil level, high discharge temperature, anti-freeze, and other protections to ensure safe and reliable operation.

·Optimized Heat Exchangers: Shell-and-tube condensers and dry shell-and-tube evaporators made of high-efficiency inner or external threaded copper tubes for superior heat transfer.

·Dual-Circuit Design (Dual-Compressor Models): Multiple refrigeration circuits – if one circuit fails, the others continue to operate, ensuring uninterrupted cooling.

·Low-Temperature Series: Available for outlet temperatures of -10°C, -20°C, and -30°C (with proper antifreeze). Can be designed to -45°C upon request. Suitable for pharmaceutical, chemical, and food industries.

APPLICATION INDUSTRIES
 

·Industrial Manufacturing: Plastic injection molding, blow molding, extrusion, chemical reactors, electroplating, anodizing.

·Pharmaceutical & Biotechnology: Fermentation, reaction vessel cooling, low-temperature storage.

·Food & Beverage: Process cooling, ingredient temperature control, cold storage.

·HVAC & Commercial: Central air conditioning for hotels, shopping malls, office buildings, airports, stadiums.

·Special Low-Temperature Processes: Pharmaceutical synthesis, fine chemical production, food freezing.
