Evaporative coolers perform best in hot, dry climates where they can reduce temperatures by up to 30°F. In humid conditions, cooling is reduced but still significant — typically 10–15°F of relief. For shops, warehouses, and job sites in humid regions, that's often enough to make a genuinely uncomfortable environment workable.
Yes. Your S&B cooler can run as a fan only by switching off the water pump — great for mild days when you need airflow without cooling. Or activate the pump first to saturate the cooling media before turning on the fan for maximum cooling performance.
Yes. S&B Evaporative Coolers work effectively in outdoor and semi-enclosed spaces like covered patios, open-air event venues, and job sites. For best results, use in low-humidity conditions — the drier the air, the greater the cooling effect.
In low-humidity conditions, the temperature reduction can be as much as 30°F — enough to make even the hottest shop, warehouse, or job site genuinely comfortable to work in.
Yes. Unlike air conditioning, evaporative coolers work by continuously drawing in fresh outside air, passing it through water-saturated cooling pads, and pushing cooled air into your space. For best results, ensure there is adequate ventilation — open doors, windows, or vents — so fresh air can flow through. Running the unit in a fully sealed space will reduce effectiveness and increase humidity.
S&B Evaporative Coolers are backed by a 1-year limited warranty on the water pump, a 3-year limited warranty on all other electrical parts and components, and a lifetime warranty on all molded parts. We build these coolers in-house, and we stand behind them.
