Be ahead of the curve with the AccuMax, Hydro System’s flagship model in our new generation of chemical dispensers. All of the features you love are now combined in one beautifully designed dilution control dispenser.

Dilution control with AccuPro Pressure Regulation Technology

Systems using AccuPro Pressure Regulation Technology eliminate dilution variance by controlling the water pressure into the unit, never allowing the dilution to “lean out” the desired dilution target. High water pressure results in improperly diluted chemicals, poor cleaning performance, and lost chemical sales. AccuPro Technology delivers accurate dilution regardless of fluctuations in water pressure.

The best feature? It has all the best features!

AccuMax is the product of over 30 years of experience in the chemical dilution industry. With all of your favorite features, the AccuMax includes:

  • 1-5 GPM flow rate options
  • New, expansive workspace to easily route tubes
  • Easy, tool-free maintenance
  • E-gap and AirGap options to satisfy regulatory standards
  • Same mounting brackets as Hydro Systems’ AccuPro and AccuDose
