HLZ Inline Inductor
Type HL-Z2 and HL-Z4

HL-Z2 HL-Z4 Froðublandarar

	High Performance inline Inductor
	Friction loss up to 5 bar does not influence proportioning rate
	Performs with all foam compounds inclucing AFFF-ARC
	Effective with 100m hose to 36m height
	Fixed induction at 3 and 6%

1. Application

Variable inline inductors are used to mix foam concentrate with water, when the foam concentrate is supplied from a tank at atmospheric pressure.

2. Recommended Foam Concentrates

The inductor performs with all types of foam concentrates, including high viscosity alcohol resistant concentrates at 3% or 6% proportioning rate and down to -10°C.

3. Installation

This in-line inductor has a better tolerance to back pressure and better foam concentrate suction than a standard in-line inductor. The HL-Z2 and HL-Z4 inductors are 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

4. Construction

The HL-Z inline inductor is constructed for a pre-determined water flow at which it creates a drop of approx. 30% in the water pressure. Foam is drawn through a 25mm pick-up tube from a container at atmospheric pressure. The preset flow of foam concentrate is continously added to the water stream.

HL-Z2 HL-Z4 Froðublandarar

Friction loss through the hose and static pressure loss of up to 5 bar does not influence the induction rate. This outstanding performance is produced by a special control valve built into the base of housing. A non-return valve prevents water flow back into the foam container once the water supply is turned off.
