Product Description

Low Volume Hydrominder 511 - 4.5 GPM

This Hydrominder 511 will keep your reservoir ready at all times with consistently and accurately mixed solutions. There's no pouring, stirring or waiting! When the solution level drops in the reservoir, the Hydrominder's float ball activates a non-electric magnetic valve.  The water flow siphons liquid concentrate into the water stream. With the Hydrominder , you can automatically maintain the level of ready to use solution. When the tank reaches past the fill level, the Hydrominder shuts off. This self-contained and self-controlled system is easy to use and maintain.

The Hydrominder 511 is built with quality, chemically resistant materials. It is environmentally friendly, as the use of concentrates reduces solid waste. Plus, it improves employee safety, since it eliminates exposure to the concentrated product. Employees will also save time and labor, as there's no manual chemical handling, measuring, and mixing required.
