AccuMax Resources

Everything you need all in one place

1) Accuracy matters

Hydro Systems’ patented AccuPro Pressure Regulation Technology comes standard with AccuMax. AccuPro Technology eliminates dilution variance to ensure your customers are always using the recommended amount of chemical. Facilities are cleaner and safer when chemicals are working properly.

2) Multiple button configurations allow for multiple chemistries to be used with the same dispenser

AccuMax features a dispenser that can handle up to three different chemistries. Instead of purchasing multiple dispensers to handle multiple chemistries, you can purchase one AccuMax dispenser and reduce your cost of ownership by up to 25%.

3) Helps meet local water regulations

Hydro's AccuMax equipment comes standard with E-Gap or Air Gap eductor backflow prevention

Water enters the system at varying pressures. Water pressure is regulated at the eductor by the Accupro technology. The regulated water pressure creates a vacuum that draws chemical at the recommended rate that provides for a consistent and expected dilution.

AccuMax dispensers are available in one, two, and three button configurations.

Yes, please contact the Hydro team to review button color options that are available based on a minimum order quantity. Example button colors are dark blue and dark grey.

Both E-Gap and AirGap.
