Angus Fire Fixed In-line Inductorsare designed primarily for use infixed installations and provide asimple and reliable method ofproportioning foam concentrate inconstant flow applications.

The range comprises six basicmodels and performance extendsfrom 65 to 4000 litres per minute atinlet pressures of between 4 and 16bar as shown overleaf. Within theselimits, the induction rate can be setaccurately between 1% and 6%.

Manufactured from high gradestainless steel with mild steelflanges and polyester internals, theunits have exceptional corrosionresistance and are suitable for usein the most extreme environments.

Each inductor is accuratelycalibrated at the factory to matchthe specific requirements of thesystem into which it is to beinstalled. To ensure that the correctperformance is achieved, thefollowing parameters must bedefined at the order stage:

(a) Required foam solution flow.

(b) Inductor input pressure.

(c) Foam type, percentage concentration and ambient temperature.

(d) Non-return valve fitted or not.

(e) Maximum suction lift.

(f) Suction pipe length and internaldiameter.

These graphs are for guidance only. Before final selection of inductor size the system parameters a-f overleaf shouldbe verified by our computer program (especially where foam pick up heights exceed 2 metres and induction rates of6% are required).

Up to 65% of the inlet pressure at the inductor (within the limits shown above) is available to power foamgenerating equipment, to overcome pipework friction losses and/or to overcome static head. Provided the back-pressure caused by the system configuration downstream from the inductor does not exceed this, foam inductionaccuracy will be maintained.

To ensure accurate proportioning, the suction lift and foam pick-up pipe length should be minimised and the watersupply pipe diameter should not be less than that of the inductor.

The flow characteristics of a non-return valve fitted to the foam pick-up pipe have to be allowed for whencalibrating the inductor and when required, the unit must be supplied by Angus. If a non-return valve is not used, itis recommended that a full bore on/off valve is fitted.
