Patent-pending Marley® WaterGard™ pre-conditions cooling tower makeup water to enable equipment operation at increased Cycles of Concentration (COC) – potentially up to 10 COC or more – reducing wastewater and overall water usage.
In an evaporative cooling system, mineral content limits determine the appropriate operating COC of the circulating water to minimize corrosion and scale tendencies.

The WaterGard cooling tower filtration system physically blocks and rejects minerals commonly found in municipal water streams (chlorides, calcium carbonate, silica, etc.), reducing makeup water mineral content and enabling higher operating COC, resulting in reduced volume requirements for both blowdown and supply water.

The Marley WaterGard filtration system is the most viable solution for operators/specifiers with plans to conserve water, especially when one or more of the following conditions is true:

1. Local operating conditions are 3 cycles of concentration (COC) or less
2. Eligible for water usage incentive or rebate programs
3. Interested in earning LEED v4 credits for cooling tower water management
