Why it matters

Evaporative cooler scale wastes water, damages pads, and reduces cooling performance

Evaporative coolers depend on water, but as that water evaporates, minerals are left behind. Over time, scale collects in the sump and on cooling pads, restricting water flow, reducing evaporation, lowering cooling efficiency, and shortening pad life. Many systems try to manage scale through excessive bleed-off or frequent flushing, which wastes water and increases maintenance demands.

Benefits

Key benefits

Focus on outcomes that matter to operators and maintenance teams: cleaner operation, preserved performance, fewer complaints, and less maintenance churn.

Save pads

Helps control mineral scale that clogs cooling pads, restricts airflow, and leads to premature pad replacement.

Save water

By helping keep minerals in suspension, Cooler Guard supports operation with reduced bleed-off once scale is under control and conditions allow.

Save time and money

Reduces the need for frequent manual pad cleaning, messy liquid treatments, and unnecessary maintenance interruptions.

  • Helps loosen existing scale: Works through the sump water to help break down existing mineral deposits so scale can begin to loosen and flush away during normal operation.
  • Non-acid treatment: Designed as a non-acid, time-release± polymer treatment to help protect pads and equipment while delivering continuous monthly scale control.
Application

How it works

Cooler Guard was designed to handle the ongoing mineral load created during evaporative cooling. Instead of relying on harsh acids, constant flushing, or messy liquid treatments, it provides a simple monthly treatment placed directly in the reservoir.
Step-by-step
  1. Place Cooler Guard directly in the sump or water reservoir of the evaporative cooler.
  2. Water activates the polymer matrix, releasing cleaners, dispersants, and descaling agents into the sump water.
  3. The unit pump distributes the treatment through the water system and across the cooler pads during normal operation.
  4. As treatment circulates, it helps loosen existing scale and keep new mineral deposits from building up on pad surfaces.
  5. Under appropriate operating conditions, Cooler Guard may support reduced bleed-off once scale is controlled.
  6. Empty the reservoir and replace Cooler Guard after 30 days.
Where it fits

Ideal for portable evaporative coolers, cool cells, greenhouses, animal barns, poultry and pig farms, and other evaporative coolers where hard water scale reduces efficiency and increases maintenance.

  • Portable evaporative coolers
  • Cool cells
  • Greenhouses
  • Animal barns, including poultry and pig farms
  • Commercial evaporative cooling systems
  • Stationary evaporative coolers in hard-water regions

Questions

FAQs

Answers to common questions about scale, duration, water savings, and pad safety.
What causes scale on evaporative cooler pads?
Scale forms when water evaporates and leaves minerals such as calcium and magnesium behind. Over time, these minerals collect in the sump and on pad surfaces, reducing water flow, airflow, and cooling performance.
How does Cooler Guard help control scale?
Cooler Guard sits in the reservoir and releases cleaners, dispersants, and descaling agents into the sump water. The unit pump then circulates the treatment through the cooler and across the pads during normal operation.
How long does Cooler Guard last?
Each Cooler Guard provides 30 days of treatment and should be replaced after the reservoir is emptied at the end of the treatment interval.
Do I need to mix or measure anything?
No. Cooler Guard is placed directly in the sump reservoir. There is no mixing, measuring, or liquid treatment to pour.
Is Cooler Guard acid-based?
No. Cooler Guard is designed as a non-acid evaporative cooler treatment.
Can Cooler Guard help reduce water waste?
Cooler Guard helps keep minerals in suspension, which may support operation with reduced bleed-off once scale is controlled and operating conditions allow.
