What is an air-cooled screw chiller?
An air-cooled screw chiller is an industrial cooling system that uses a screw compressor and air-cooled condenser to produce chilled water for process cooling and HVAC&R applications. It removes heat using ambient air, eliminating the need for cooling towers and condenser water systems.
How does an air-cooled screw chiller work?
The chiller compresses refrigerant gas, rejects heat through an air-cooled condenser, expands the refrigerant through an expansion device, and absorbs heat through the evaporator. The resulting chilled water is circulated to industrial processes or building cooling systems.
What is the difference between an air-cooled and water-cooled screw chiller?
Air-cooled screw chillers reject heat directly to ambient air and do not require cooling towers or condenser water. Water-cooled chillers require cooling towers and water treatment but may offer higher efficiency in large-scale installations.
What capacity air-cooled screw chillers does Airtech manufacture?
Airtech manufactures customized air-cooled screw chillers across multiple capacity ranges for industrial applications. Standard and custom configurations are available based on cooling load, process requirements, and site conditions. Exact capacity ranges should be confirmed with Airtech's engineering team.
What is the price of an air-cooled screw chiller?
The price depends on cooling capacity, refrigerant type, control options, operating temperatures, and project-specific requirements. Contact Airtech for a customized quotation based on your application and cooling load.
Which refrigerants are used in Airtech air-cooled screw chillers?
Airtech chillers can be configured with R-404A, R-407C, R-410A, and R-134a refrigerants depending on application requirements, operating conditions, and environmental considerations.
What temperature range can an air-cooled screw chiller achieve?
Airtech air-cooled screw chillers are designed to operate across a temperature range from +12°C down to −40°C, depending on system configuration and process requirements.
What industries use air-cooled screw chillers?
These chillers are widely used in plastics processing, pharmaceuticals, food and dairy processing, chemical manufacturing, breweries, HVAC&R systems, packaging facilities, and other industrial process cooling applications.
Does an air-cooled screw chiller require a cooling tower?
No. Air-cooled screw chillers reject heat directly to ambient air through condenser coils and fans, eliminating the need for cooling towers, condenser water pumps, and water treatment systems.
Who is a leading air-cooled screw chiller manufacturer in India?
Airtech Cooling Process Pvt. Ltd. is a leading Indian manufacturer of industrial cooling systems, offering customized air-cooled screw chillers, process chillers, and refrigeration solutions for domestic and international markets.
What maintenance does an air-cooled screw chiller require?
Routine maintenance typically includes condenser coil cleaning, filter inspection, refrigerant checks, electrical inspections, and periodic performance monitoring. Air-cooled systems generally require less maintenance than water-cooled alternatives.
Can air-cooled screw chillers operate in tropical conditions?
Yes. Airtech air-cooled screw chillers are designed for demanding industrial environments and can operate reliably in high ambient temperatures commonly experienced across India and tropical regions.
