The Best Defense Against Evaporative Cooler Scale

  • Save Cooling Pads
  • Save Water
  • Save Time & Money
  • Cooler Guard is a 30-day time-release± treatment that prevents and dissolves scale on evaporative cooling pads. It allows the system to run with the bleed-off valve turned off, offering significant water savings.

    Place Cooler Guard in the reservoir and let it do all the work to keep cooling pads clean and efficient.

    Save Water

    Once scale is dissolved, Cooler Guard allows for the evaporative cooler bleed-off valve to be turned off, saving gallons of water per day. The water saving value of Cooler Guard saves money and is better for the environment.

    Cooler Guard releases cleaners, descaling agents, and dispersants into the sump water, eliminating the need to clean pads manually. Cooling pads last longer and cool more efficiently.

    What causes scale on Evaporative Cooling Pads?

    Scale formation on cooling pads is primarily caused by the evaporation of water, which leaves behind minerals. Water deposits minerals such as calcium and magnesium on the cooling pads as water evaporates. The concentration of these minerals in water, often referred to as 'water hardness,' directly impacts the amount of scale accumulation; the harder the water, the more minerals that are left behind, and the greater the buildup over time.

    This accumulation of mineral deposits, or 'scale,' on cooling pads has several detrimental effects on the performance and efficiency of cooling units. Scale acts as an insulating layer on the pads, hindering water absorption and evaporation, which are key processes for effective cooling. As a result, units with scaled pads must work harder to achieve the desired cooling effect, leading to increased water consumption, higher energy usage, and accelerated corrosion. Ultimately, scale buildup significantly reduces cooling efficiency.

  • Minerals such as calcium and others are found in water
  • When water evaporates, minerals are left behind
  • The 'harder' the water the more minerals left behind
  • Mineral deposits continue to build over time
  • Cooling pads before and after using Cooler Guard

    How Does Cooler Guard Work?

    Cooler Guard offers superior performance by design. Cooler Guard emits time-release± cleaners, descaling agents, and dispersants into the sump water, which is then circulated by the units' pump. It is effective at dissolving current scale and other buildup as well as guarding against future scale deposits. Cooler Guard keeps scale in suspension and cooling pads effective. Cooler Guard's ability to keep scale from settling on pads, also allows the unit to run with the bleed-off valve turned off.

    Place Cooler Guard in the reservoir (Sump). It's activated by the water to time-release± cleaners, descaling agents, and dispersants that prevent scale. It's that simple.


    Cooler Guard Placed in the Sump
  • Water Activated
  • Non-dissolving polymer leaves no residue behind
  • Releases cleaning agents, dispersants, and descalers
  • Time-Release±
  • Cooler Guard treats water for 30 days
  • Multiple Sizes Available
  • Dissolves the build-up that causes corrosion
  • Cooler Guard prolongs the viable life of cooling pads

  • How does Cooler Guard Remove Scale on Pads?

    Cooler Guard sits in the reservoir, continually releasing cleaners, descaling agents, and dispersants into the sump water. The pump distributes these agents throughout the cooling pad. With the bleed-off valve off, the concentration steadily breaks down scale and other buildup. Scale will begin to crumble like sand. Empty the reservoir and Replace Cooler Guard after 30 days. That's all it takes to remove scale from cooler pads when using Cooler Guard.

    Save Water, Save Money

    Cooler Guard Saves a lot of water. It's ability to keep scale in suspension, allows for the system to run with the bleed-off valve off. It's only necessary to change water when replacing Cooler Guard in the Sump (reservoir).

    If you discharge even 1 gallon of water from your cooler a minute, this amounts to over fourteen hundred gallons per day. Wasted water is an added expense and costly to the environment.
