Frequently Asked Questions.
What is an air cooled screw chiller, and where is it used?
An air cooled screw chiller is an industrial refrigeration system that:
- Uses a screw compressor to deliver chilled water for process cooling or building air conditioning
- Rejects heat directly into the ambient air through condenser fans
- Is commonly used in factories, commercial buildings, data centers, and facilities where water is scarce or cooling towers are impractical
What are the main advantages compared to water cooled chillers?
Key benefits include:
- No cooling tower required: Simplifies installation and reduces water consumption
- Lower installation cost: No need for condenser water pumps or cooling tower piping
- Simpler maintenance: Fewer components and no water treatment system
However, air cooled chillers can be less efficient in very high ambient temperatures compared to water cooled units.
Are air cooled screw chillers energy-efficient?
Yes. Many models feature:
- High-efficiency screw compressors
- Advanced microprocessor controls to optimize part-load performance
- Variable speed fans to reduce energy consumption during low demand
Efficiency ratings vary by capacity, operating conditions, and model.
What cooling capacities are available?
Air cooled screw chillers typically range from approximately 50 tons to several hundred tons of refrigeration. For exact sizing, our team can help assess your process or HVAC requirements.
