Dual Compressor Water-Cooled Screw Chillers


Engineered with robust refrigeration capacity for high-load applications, these energy-efficient water-cooled screw chillers excel in both industrial and commercial cooling systems.


As a professional manufacturer and supplier specializing in dual-compressor water-cooled screw chillers, DARO Chiller brings over 15 years of technical expertise to critical temperature control solutions.


When your project requires: Lower noise levels than air-cooled chillers Or Compact installation footprint, or Superior refrigeration efficiency, Water-cooled screw chillers emerge as the ideal technical choice.


DARKO Chiller's high-quality water-cooled screw chillers feature the following significant advantages:


1. We offer a complete product line with cooling capacities ranging from 30 to 500 refrigeration tons, meeting diverse industrial process cooling needs.


2. Our water-cooled screw chillers are designed with single or dual refrigerant circuits based on your thermal load requirements. The dual-circuit design enhances part-load efficiency, reducing your power consumption.


3. The chillers incorporate an optimized forced cooling design to maximize cooling capacity and efficiency. High-efficiency corrugated tubes increase heat exchange area, enhance refrigerant turbulence within tubes, and improve heat transfer performance.


4. The dry-type shell-and-tube evaporator minimizes refrigerant charge, ensures excellent oil return performance, and eliminates the need for external oil pumps or oil return filters. With no vulnerable components, maintenance costs are low. The refined refrigerant inlet/outlet distribution eliminates asymmetry, further boosting heat transfer efficiency.


5. Standard-equipped solid-state starters enable controlled acceleration and deceleration, reducing compressor stress and vibration.


6. All chillers use eco-friendly refrigerants (R407c, R-134a, or R410a) with zero ozone depletion potential (ODP) and no phase-out schedules.


7. Each unit features an advanced microcomputer control system with a clear, user-friendly LCD touchscreen interface. Alternatively, a PLC control system supports integration with your universal control software.


8. These chillers are widely applicable for industrial cooling processes in plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, and food processing, as well as central air conditioning projects requiring chilled water in shopping malls, hotels, factories, and hospitals.
