Proportioners

Foam Proportioners Description

The foam proportioners are used for mixing water at low, medium, or high expansion foam concentrate to feed either portable nozzles or small stationary plants. For the later case, the total flow rate must equal the flow rating of the mixer at its outlet pressure.
They provide an inexpensive foam proportioning means for system requiring fixed flow rates and where available water supply pressures are adequate. The pressure drop across the foam proportioner will be approximately 30% of the supply line pressure, for this reason the typical operating pressure at the inlet of the foam proportioner should be between 5 - 8 bar (72.5.5 - 116 psi) depending on the model.
SE-Z

SE-Z

Foam proportioner mod. SE-Z
For portable or fixed installations. Variable dosage.
SE-ES

SE-ES

In line mixer mod. SE-ES
Used for mixing water at low, medium, or high expansion foam concentrate to feed either portable nozzles or small stationary plants. For the later case, the total flow rate must equal the flow rating of the mixer at its outlet pressure.
SE-VZ

SE-VZ

Balanced pressure proportioner mod. SE-VZ
It makes a constant mixture of foam liquid and water, regardless of the change in water pressure.
