Frequently Asked Questions

Portable Unit FAQs

Q: How much area can a portable evaporative cooler fan cool?
Coverage depends on CFM rating, airflow direction, and ventilation. Portable units typically support spot cooling or zone cooling rather than whole-building cooling.

Q: Do portable evaporative coolers need ventilation?
Yes. Fresh air exchange improves performance. They work best in open or semi-open spaces.

Q: Do they use a lot of electricity?
No. Evaporative coolers typically use far less electricity than compressor-based air conditioners.

Q: Can I use this in a garage?
Yes, garages and workshops are one of the most common use cases.

Industrial Unit FAQs

Q: Are evaporative coolers effective in warehouses?
Yes. They are widely used in warehouses and large open facilities where AC is not practical.

Q: Do industrial evaporative coolers replace AC?
They can replace or supplement AC depending on layout and climate conditions.

Q: How are they installed?
Most PolarCool units are portable and require only power and water — no ducting required.

Q: How much maintenance is required?
Basic maintenance includes pad inspection, cleaning, and seasonal servicing.

Outdoor Unit FAQs

Q: Do evaporative coolers work outdoors?
Yes, they are commonly used outdoors and in covered outdoor areas.

Q: Will humidity affect performance?
Higher humidity reduces cooling efficiency. They perform best in dry to moderate climates.

Q: Can they run continuously?
Yes, when properly supplied with water and power.
