Save labor by mixing faster than by hand

Automatic models save even more by keeping containers full unattended

More accurate than hand mixing

Safer because less contact with concentrates

Lean coolant mixtures can cause excessive tool wear, corrosion on parts and machines, and increased bacteria growth

Rich coolant mixtures can cause sticky or slippery residues, operator irritation, and waste expensive concentrate

Lean cleaner mixtures won't perform as intended

Venturi types use water passing over an orifice to create suction that draws the concentrate from the container and mixes it with the water.  Concentration is controlled by either changing orifice size or turning a metering valve.  These units can not operate with any back pressure, so they can only be used to fill a pail or nearby container.  Accuracy is also affected by water pressure and concentrate level.

Link to Venturi Proportional Mixers

Water Driven Pumps use water to drive a piston which pumps concentrate into a mixing chamber where it is mixed with the water.  Concentration is not affected by water pressure or concentrate level, which makes them very accurate.  These units can be hooked up in-line or to a hose reel and are typically used in central distribution systems.

Note  Plumbing codes in some areas may require a backflow preventer or other types of controls before the mixing system.  Also, it is always recommended (and required for the warranty) to install a screen filter before the mixer.

The only non-electric, water-driven injector where the chemical is mixed in a patented internal mixing chamber separate from the motor, extending the life of the motor and reducing service and replacement costs.

Proprietary blend of highly chemical compatible materials results in a significantly stronger body and cover, allowing for the industry's highest operating pressure capabilities.

Lower body has more open ports entering and exiting the unit, reducing pressure loss.

Innovative mixing chamber design ensures a thorough and precise mixing of the water and injected chemical before leaving the unit.
