Fomtec HPZ 400 Inductor

Dafo Fomtec AB

The Fomtec HPZ 400 Inductor is constructed for a pre-calculated water flow. It creates a pressure drop in the water pressure of about 30-33% at that flow.

Foam is drawn through a 25 mm pick- up tube from a container at atmospheric pressure. The pre-set flow of foam concentrate is continuously added to the water stream.

Friction loss through the hose and static pressure loss of up to 5 bars does not influence the induction rate.

A special control valve built into the base of housing produces this outstanding performance. A non-return valve prevents water flow back into the foam container once the water supply is turned off.

Application

Variable in-line inductors are used to mix foam concentrate with water when the foam concentrate is supplied from a tank at atmospheric pressure. This in-line inductor has a better tolerance to back pressure and better foam concentrate suction than a standard in-line inductor.

The Fomtec HPZ 400 Inductor is connected to the water line. They can be placed far from the foam branch-pipe, as they can accommodate up to 5 bar pressure loss in the hose.

Recommended Foam Concentrates

The inductor performs with all types of foam concentrates, including high viscosity alcohol resistant concentrates at 3% or 6% proportioning rate.

Options

The HP inductors could be delivered with the following options:

  • Stortz couplings
  • BS-couplings
  • Different mixing ratios
  • Fomtec HPZ 400 Inductor
