Choose a CLOSED-CIRCUIT Cooling Tower when:
- The process fluid must stay clean (e.g., cooling lasers, medical imaging, injection molds, food processing).
- The equipment being cooled is expensive and sensitive to scale or corrosion (e.g., industrial chillers, reactors).
- Freeze protection is required and glycol use is planned.
- The installation site is dirty, dusty, or space-constrained (possible indoor installation).
- Water or chemical treatment costs are high – you want to minimize long-term operational expenses.
- System reliability and reduced maintenance are critical priorities.
Choose an OPEN CIRCUIT Cooling Tower when:
- Lowest possible initial cost is the overriding factor.
- The process fluid is non-critical, tolerant of contamination, or the system is disposable (e.g., some basic air compressor cooling).
- The environment is clean and temperatures are mild (no freezing risk).
- You have ample space outdoors and simple access for water treatment service.
- The application is traditional, non-sensitive HVAC with a standard water-cooled chiller, and the local water quality is good/treatment is economical.
