Air-cooled water chillers are industrial refrigeration units utilizing air-exchange technology to provide stable closed-loop cooling for temperature-sensitive industrial processes.
Cooling Working Principle
Air and water flow in opposite directions inside the tower
Heat is transferred from water to air through contact exchange
Hot circulating water enters from the top and is evenly distributed
Air enters from the side and passes through the fill media
Cooled water is collected at the bottom basin for recirculation
Working principle
The closed cooling tower runs on a sealed internal loop with external spray cooling and forced-air heat exchange.
It integrates internal circulation, spray water, airflow exchange, and control units into a closed-loop cooling system.

FAQ
Q1: What data is needed to select a cooling tower model?
Provide circulating water flow rate, inlet/outlet temperature, and ambient conditions.
Q2: How does a closed cooling tower differ from an open one?
It uses a closed circuit with tube coils, isolating the process fluid from ambient air.
Q3: Is water treatment required?
Closed loop reduces contamination and scaling risk, but periodic maintenance and water quality monitoring are recommended.
Q4: Can it support non-water fluids?
Some designs support oil and other fluids through appropriate heat exchanger selection.
