Practical, entry-level venturi dilution unit, delivering accurate dilution control in the most arduous environments

AccuDose® and AccuDose Select dilution control dispensers are an economical way to dispense a wide variety of automatically diluted solutions into spray bottles, buckets or other containers at the touch of a button. Dilution is controlled by drawing chemicals through metering tips of varying size and injecting this metered amount into the water flow.

AccuDose dispensers are available with E-Gap or Air Gap eductors.

Made from durable plastic construction, it is possible to dispense up to 5 products, so it is ideal for dispensing all types of liquid surface and floor cleaning products at the point of use. It’s usually situated in kitchens and food preparation areas – or in janitorial rooms where the cleaning chemicals are situated.

Users will also appreciate the ease of operation and low service requirements of the AccuDose line. Simply turn a knob to select the dilution product desired, then push the button to dispense ready-to-use solution. Since each standard button can be converted to lockability in the field, customising the standard systems to individual needs is simpler than ever.
