PolyUnit is a reliable and popular dosing system for liquid polymer mixing.

Our PolyUnit liquid polymer dosing units, PB10Evo and PB30, are designed for reliable dosing and mixing of liquid polymer / flocculants for wastewater treatment plants.

The units are built with quality components in a strong, stainless cabinet. Both models provide strong standard facilities such as remote activation and remote monitoring of flow errors.

For correct mixing of the polymer emulsion, adjustments of water flow, water pressure and polymer amount are made in the PolyUnit. On the front of the unit, current water flow is shown via an electronic flow meter as well as current water pressure on a pressure gauge. In the PB30 model, current polymer flow can also be displayed directly on the front of the unit.

All connections for built-in options and external activation and error signals are built into the standard model.

The electric control panel is built with DIN rail components for easy troubleshooting and replacement.

Servicing and replacing components is simple as the cover can be completely removed.
