The Gemini™ Model 25 Mixing Station is a unique chemical proportioner that will simultaneously dilute and blend two chemical concentrates into one accurately diluted solution and dispense it into any sized container. The unique Gemini™ "double venturi" injection system incorporates two completely separated venturis in one injector body and uses city water pressure (25 - 125 PSI) to draw and blend 2 chemical concentrates into the water stream independently so that the chemicals never mix until they are diluted. Dilution ratios are controlled independently with precision metering tips. Ball valve activation allows for hands-free dispensing.
