Product Description
he Aidear Industrial Water-Cooled Screw Chiller is a high-performance, heavy-duty refrigeration system engineered for large-scale cooling demands. As shown in the workshop photo, this unit features multiple semi-hermetic green screw compressors arranged in a parallel configuration for redundancy, capacity control, and energy efficiency, integrated with a large vertical oil separator, oversized receiver tank, shell-and-tube condensers/evaporators (with visible flanged connections and piping), advanced valve assemblies, robust gray electrical control enclosure, heavy steel base frame with mounting legs, and safety warning labels—ensuring reliable, continuous operation in industrial settings.
This parallel multi-compressor design allows staged loading/unloading, precise temperature control, and high part-load efficiency, while the water-cooled heat exchangers provide superior heat rejection using cooling tower or condenser water loops. Fully customizable to match specific project requirements, it delivers stable chilled water supply with low energy consumption and minimal maintenance.
Product Type: Water-Cooled Screw Chiller / Parallel Multi-Compressor Refrigeration Unit / Industrial Screw Chiller Rack
Compressor Type: Semi-hermetic twin-screw or single-screw compressors (multiple units in parallel for capacity staging and failover)
Refrigerant: R134a, R410A, R404A, or low-GWP alternatives (eco-friendly options available)
Oil Management: Built-in or vertical cyclone/coalescent oil separator with reservoir, automatic oil return system, and level controls for stable lubrication across compressors
Heat Exchangers: Shell-and-Tube type condenser (water-cooled) and evaporator (flooded or falling-film for high efficiency); copper tubes standard, stainless steel options for corrosive fluids
Casing / Frame Material: Heavy-duty galvanized or stainless steel enclosure/frame for corrosion resistance and industrial durability
Control System: PLC or advanced microprocessor controller with touch interface, capacity modulation (stepped or stepless via VFD/inverter options), monitoring of pressure/temperature, and fault diagnostics
Operating Medium (Chilled Side): Water, Glycol mixtures (for low-temp or antifreeze applications)
Cooling Medium (Condenser Side): Cooling tower water or closed-loop water
Capacity Control: Multi-stage (e.g., 25%-50%-75%-100%) or continuous variable speed; parallel setup enables precise load matching
Design Pressure: Standard or high-pressure capabilities (customizable for shell, tubes, and refrigerant side)
Additional Options: Variable frequency drives (VFD) on compressors, heat recovery modules, economizers, low-ambient kits, BMS integration, noise reduction enclosures, and certifications (CE, ASME, etc.)
The parallel screw compressor configuration maximizes uptime through compressor redundancy (if one fails, others continue), while delivering high COP/EER values through efficient oil separation, low approach temperatures in shell-and-tube exchangers, and optimized flow paths. Water-cooled design eliminates air-side limitations, offering quieter operation, higher efficiency in hot climates, and suitability for indoor installations. Easy access for maintenance (e.g., removable panels, service valves), long service life, and reduced energy costs make it ideal for continuous-duty applications.
