4 Products,
1 Accurate Technology

The AccuMax 4P continues Hydro Systems’ new product line of chemical dispensers. Up to 4 chemicals can be housed within the 4P unit. It can accommodate most 2-3 litre bottles. Your chemicals are stored behind locked enclosures to protect both the users and your brand.


Protect Your Brand
With the AccuMax 4P, you get plenty of opportunities for custom branding. Not only can you brand the unit with your company’s colors and logo, you can also choose to have it pre-plumbed in our factory.

Accuracy Matters
Hydro Systems’ patented AccuPro Pressure Regulation Technology comes standard with the 4P. 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. Be confident in your chemical dilution with the AccuMax 4P.
