Use Case Examples
Air-Cooled:
●Rooftop supermarket refrigeration.
●Cold storage in inland locations with moderate climate.
●Easy-to-install replacement units.
Water-Cooled:
●Central HVAC plants in high-rise buildings.
●Marine and offshore cooling where sea-water cooled systems excel.
●Large food processing facilities needing stable cooling year-round.
Conclusion
Both air-cooled and water-cooled condensers have distinct advantages.
● Air-Cooled: Lower installation and maintenance costs; ideal for space-limited setups.
● Water-Cooled: Higher energy efficiency and performance consistency, especially in 
high ambient or marine conditions.
