Treat the recirculating sump water
Place Cooler Guard directly in the reservoir so the time-release polymer works through the water already circulating in the system.
Review sump application →Agriculture & heat management
Use a system-level approach to manage mineral scale in evaporative-cooling reservoirs and pads across poultry, livestock, greenhouse, and commercial operations.
Start with the cooling system
Evaporative coolers continually concentrate minerals as water evaporates. Cooler Guard is placed in the sump reservoir to support ongoing scale-control maintenance through the circulating water.
Place Cooler Guard directly in the reservoir so the time-release polymer works through the water already circulating in the system.
Review sump application →Scale can restrict water distribution and airflow across evaporative-cooling pads. Ongoing water treatment supports a cleaner pad-maintenance program.
Explore scale-control benefits →Once scale is under control and operating conditions allow, Cooler Guard can support system management with reduced reliance on excessive bleed-off.
Review product guidance →Each Cooler Guard is designed for 30 days of treatment, making replacement easy to connect to a recurring service schedule.

Prepare for demanding heat
Cooler Guard works as one part of normal evaporative-cooler inspection, cleaning, water management, and pad maintenance—not as a substitute for the rest of the system program.

Cooler Guard is placed directly in the evaporative-cooler sump reservoir. Follow the product directions for quantity, placement, and operating conditions.
Each treatment is designed for a 30-day interval. Build replacement into the cooling system’s existing monthly inspection and maintenance schedule.
No. Cooler Guard supports scale-control maintenance but does not replace routine inspection, cleaning, water management, or equipment service.
