Concentration Calculators INCREASE CONCENTRATION (NEW/FULL SYSTEM) If the system is empty, or doesn’t have adequate capacity to add fluid without having to drain some of the existing fluid, the following calculator can be used to determine the amount of solution to drain from the system and the number of gallons of concentrated heat transfer fluid to add to the system to increase the glycol concentration: Product Name Select ProductGlycoChill+™ P-200 Heat Transfer FluidGlycoChill+™ P-200FG Heat Transfer FluidGlycoChill+™ P-200HD Heat Transfer FluidGlycoChill+™ E-200 Heat Transfer FluidExo Endosol+™ 101 Geothermal FluidGeoChill+™ M-700 Geothermal Fluid Current System Concentration (%) (For new systems enter 0%) System Volume (gallons) Desired System Concentration (%) Amount of Concentrate Required (gallons) INCREASE CONCENTRATION (PARTIAL SYSTEM) If the system has adequate capacity to add fluid without having to drain the existing fluid, the following calculator can be used to determine the number of gallons of concentrated heat transfer fluid to add to the system to increase the glycol concentration: Product Name Select ProductGlycoChill+™ P-200 Heat Transfer FluidGlycoChill+™ P-200FG Heat Transfer FluidGlycoChill+™ P-200HD Heat Transfer FluidGlycoChill+™ E-200 Heat Transfer FluidExo Endosol+™ 101 Geothermal FluidGeoChill+™ M-700 Geothermal Fluid Current System Concentration (%) Volume of Solution (gallons) Desired System Concentration (%) Amount of Concentrate Required (gallons) Final Volume (gallons) DECREASE CONCENTRATION To decrease the glycol concentration, the following calculator should be used to determine the volume of fluid to drain from the system and replace with high quality water: (Water Quality Specification) System Volume (gallons) Desired System Concentration (%) Current System Concentration (%) Amount of Water Required (gallons)
