Product Performance & Application

How much area can a PolarCool unit cool?
Coverage depends on the model’s CFM rating, airflow direction, and ventilation. PolarCool units are ideal for spot cooling, zone cooling, or air circulation across large industrial areas

Can evaporative coolers replace traditional air conditioning?
Yes, in many industrial and commercial environments. They can replace or supplement AC systems in large, open, or high-bay facilities where traditional AC systems are impractical or costly

What is the expected temperature drop?
Typical results vary with temperature and humidity:

• Hot & Dry (100°F / 20% RH): ~23°F drop
• Warm & Dry (80°F / 20% RH): ~17°F drop
• Hot & Humid (95°F / 50% RH): ~13°F drop

Even in humid conditions, you can expect 10°F–13°F cooling, ideal for manufacturing floors and equipment zones

Do evaporative coolers work in humid environments?
Yes. PolarCool systems use advanced CELdex™ cooling media that still deliver measurable cooling even in humid regions. Many of our clients report significant comfort gains in Gulf Coast and Southern U.S. climates

How much noise does a PolarCool fan make?
PolarCool fans operate at relatively low noise levels for their high output, typically ranging from 53 to 68 decibels, comparable to a busy office environment. The units are designed for, and often used in, commercial or large workshop settings where the noise is generally not considered disruptive.

Can I use the cooler outdoors or in partially open spaces?
Absolutely. PolarCool units excel in semi-open or open-air facilities, such as loading bays, outdoor service areas, and athletic training spaces

Operation & Maintenance

Do PolarCools units need ventilation?
Yes — fresh air circulation is critical for peak performance. Operate units with doors, vents, or bay openings available to prevent humidity buildup.

Do I need a constant water supply?
No. Units include a hose connection for automatic refill. If connected to a constant water source, a float valve prevents overfilling. Large capacity reservoirs offer flexibility depending on your facility’s water access.

Can the fan and pump operate independently?
Yes. You can run either the fan or the pump separately; however, full evaporative cooling requires water flow over the media.

How much humidity is added to the environment?
In well-ventilated areas, humidity increase is typically 2%–5% — negligible for most industrial or commercial operations

What maintenance is required?

• Daily: Run the fan for 15 minutes after pump shutdown to dry pads.
• Weekly: Drain water tanks and clean cooling media surfaces.
• Seasonal: Inspect pads, float valves, and fittings; clean and dry before storage

How long does the cooling media last?
With proper maintenance and clean water, Celdek™ media typically lasts 5+ years

What is the black coating on the cooling media?

MI-T-edg coating improves pad life. The strongest, most weather resistant edge coating available and is the only edge coating with patented algae resistance.

What should I do before storing my unit?
Drain all water, dry the pads, disconnect power, and cover the unit with a PolarCool protective cover

Setup & Power

What power source do I need?
Most PolarCool models run on a standard 115V outlet. Larger (48” models) industrial units may require a dedicated circuit; refer to your product’s specification sheet for amperage and voltage details.

Is assembly required?
Minimal. Units are ready to use out of the box. Remove shipping tape from the float valve before operation

Warranty & Support

What warranty comes with my PolarCool unit?
All products are backed by a comprehensive manufacturer’s warranty. Visit polarcool.net/warranty-info for full details and registration

How do I get service or replacement parts?
Parts and consumables are available directly at www.polarcoolstore.com. For troubleshooting, contact Customer Service at (888) 765-5732.

Performance Tips

• Position units to maximize cross-ventilation and airflow patterns.
• Use multiple smaller units for zoned cooling in large facilities.
• Maintain clean water supply to extend pad life and efficiency.
• Pair units with ceiling fans or HVLS fans for destratification and even air distribution.
