Prime proportional dosing equipment for water treatment with water samples on site in New Zealand

Dosing Systems

Manual and proportional chemical dosing systems for sediment and pH control.

Choose your level of control

Manual dosing gives you a simple, hands-on way to control chemical addition on site. Where dosing needs to track flow, proportional systems adjust chemical dosing automatically as flow changes. Across the range, options include tank-mounted or standalone setups, dual dosing, and solar or mains power.

The right setup comes down to how you want dosing controlled, where the unit will sit and what power is available.
