<p>HydroMaster drum or wall-mounted proportioners automatically mix liquid concentrates with water and dispense the diluted solution into any container.  Manual mixing of concentrates with water is time consuming and imprecise — the strength of the diluted solution may be too strong one time and too weak the next.  Automatic dilution with the HydroMaster takes this variability out of the cleaning system, so the concentrated cleaning product consistently delivers maximum performance.  HydroMasters use water power, not electricity, so concentrates don’t have to be located near outlets, just within a hose’s reach of a water source.</p> <p>Venturi type mixers use water passing over an orifice to create suction that draws the concentrate from the container and mixes it with the water.  Concentration on the HydroMasters is adjusted by changing the orifice size. These units cannot operate with any back pressure, so they can only be used to fill a pail or nearby container.  They <strong><em>cannot </em></strong>be used with any type of sprayer or shut-off valve on the discharge side.  Accuracy can be affected by water pressure and concentrate level.</p> <p><strong>HydroMaster Features & Benefits:</strong></p> <ul> <li>Economically priced</li> <li>High quality, chemically resistant materials</li> <li>Wall or drum mounted</li> <li>Water powered; non-electric</li> <li>Works well for small shops; enhanced safety</li> <li>Increase productivity of employees</li> <li>Ideal for all-purpose or specialized cleaners strippers, degreasers, soluble oil and synthetic coolants, and fertilizers</li> <li>Must have a back flow preventer installed in some areas</li> </ul>
