Fixed In-line Inductors

Angus Fire Fixed In-line Inductors are designed primarily for use in fixed installations and provide a simple and reliable method of proportioning foam concentrate in constant flow applications.

The range comprises six basic models and performance extends from 65 to 4000 litres per minute at inlet pressures of between 4 and 16 bar as shown overleaf. Within these limits, the induction rate can be set accurately between 1% and 6%.

Manufactured from high grade stainless steel with mild steel flanges and polyester internals, the units have exceptional corrosion resistance and are suitable for use in the most extreme environments.

Each inductor is accurately calibrated at the factory to match the specific requirements of the system into which it is to be installed. To ensure that the correct performance is achieved, the following parameters must be defined at the order stage:

  • Required foam solution flow.
  • Inductor input pressure.
  • Foam type, percentage concentration and ambient temperature.
  • Non-return valve fitted or not.
  • Maximum suction lift.
  • Suction pipe length and internal diameter.
