Normal Operation
The i-Flow 6000 Gas Generator is designed specifically to minimize operator
involvement. As long as the system is installed as described in earlier sections and is
serviced in accordance with the specified maintenance recommendations (see Service
Requirements), then it should simply be a matter of turning the Generator on. Note: the
generator will only produce nitrogen gas based on demand, so should typically be left
in a powered state, live compressed air supply. If the system is shutdown, or suffers a
power failure, it will restart automatically. However, if left without inlet air pressure for a
prolonged period and the Nitrogen Process tank is allowed to vent all pressure, then the
commissioning process above should be repeated to purge the oxygen from the system
before high quality nitrogen gas can be produced again.
The Generator will automatically produce the factory set flow and pressure.
Note: The side panels of the generator should not be removed during
operation unless you have received training and are technically
competent to manage the potential risks present. Located inside the
cabinet are the vent silencers and safety relief valve, which periodically
release gas at pressure and could cause injury.
Inspection plugs are located on the rear and top of the generator.
These plugs must NOT be removed whilst the system is under pressure.
If removed, it is likely that pressure will be released violently and cause
injury.
Safe Isolation Process
To shut the system down, close the inlet air supply valve (1), BUT leave the electrical
power on to the generator. Close the nitrogen outlet valve (4) to the application, and
slowly open the bypass / commissioning valve (3) to allow the nitrogen product gas
to vent to atmosphere. NOTE: do not isolate the Process Tank valves (5) as this will
trap pressure in the tank. For the product to be completely safe to continue work, ALL
pressure must be fully dissipated. Ensure ALL front panel gauges read zero before
turning off the power on the front panel and removing the mains cord from the left
hand side of the generator before proceeding. Note: Due to the nature of the Carbon
Molecular Sieve it could take considerable time for the generator to release all the
trapped oxygen. The bypass valve (3) should remain open at all times, allowing the CMS
to release oxygen and pressure can build again if closed.
Once service operations have been completed, the generator can be re-connected to
the mains supply and the Commissioning process described in earlier sections should
be repeated.
Due to the simplicity of the design and the small number of moving parts the i-Flow
6000 Series Nitrogen Generators will have a long and trouble free life. However as with
all scientific and technical equipment it should be regularly inspected and serviced as
below.
