Nitrogen Panel
The nitrogen panel fitted to the base frame allows the supply of nitrogen to a number of different
points on the machine.
Each device consists of a pressure regulator and a flow meter to adjust pressure and volume flow
separately.
The following devices are available:
●
The barrier gas system for sealing systems on motor side. This device is equipped with a flow
switch integrated to the flow meter to switch off the machine if the nitrogen volume flow drops
below the minimum set flow value.
●
The dilution gas ballast prevents the formation of condensates or dilutes them, depending on
the application. The nitrogen is fed into the cylinder.
●
The purge gas system fitted at the inlet flange allows to flush the machine after use or during
operation. The nitrogen is fed into the inlet flange.

Pressure Switch (Barrier Gas)
The pressure switch monitors the barrier gas pressure. It is only available if the machine has been
equipped with gas lubricated double mechanical seals.
The machine must be stopped if the barrier gas pressure is below 2.5 bar, see Wiring Diagram Pres-
