HVAC Evaporative Cooler Treatment

Continuous Scale Control for Evaporative Coolers

Cooler Guard® is a time‑release evaporative cooler treatment that dissolves existing mineral scale and prevents new deposits from forming on cooling pads. Activated by water in the sump, each polymer block releases cleaners, descalers, and dispersants that keep pads clean, improve cooling efficiency, and reduce water usage by allowing many systems to operate with the bleed‑off valve turned off.

• Save Pads: Prevents and dissolves scale buildup, extending pad life
• Save Water: Helps eliminate daily bleed‑off, reducing water consumption
• Save Time & Money: Minimizes manual cleaning and supports efficient cooling
• Application: Place directly in the cooler sump; replace every 30 days
• System Compatibility: Suitable for portable units, cool cells, greenhouses, livestock barns, and large evaporative cooling systems

Commercial Shipping Only: Cooler Guard® products cannot be shipped to residential addresses and are available for commercial delivery only.
