Principle
These stations are used to supply air/gas premix to a set of burners distributed in several control zones for the heating of furnaces or feeders.
The ERFI stations are composed of:
- Mixer(s)
- Combustion air fans
- Gas line(s) (filtering, expansion, counting and safety)
- Automatic regulation(s) of zone with by-pass of small fire and breakdown service
- Cabinet(s) of control and safety
All the equipment is fully assembled and cabled on a tubular chassis. It is also tested in our workshops.
This station, delivered on site, will only require gas connections, zone connections and electrical control / command connections from the control room.
Each premix zone piping will be protected against flashback.
