Commissioning
With the generator installed as previously described, connect the application to the
Nitrogen output port and open the air supply to the unit. On reaching operational
pressure the generator will produce Nitrogen at the customer-specified purity. The
design of the generator is such that it will deliver up to the rated output flow of
Nitrogen, determined by demand of the consuming equipment. Rated flow, purity
and pressure are installation specific and dependent on inlet conditions being met as
detailed on the individual generator
The design of the generator is that it will deliver variable purity dependant on the
inlet pressure and outlet flow rate. Outlet pressure may be adjusted by the pressure
regulator inside the unit, allowing for up to 15 psi pressure drop across the system.
Should the demand for the nitrogen stop, the generator will automatically go into
"eco-mode" (refer to page 18), shutting off the air inlet. Once the demand restarts
the generator automatically resumes producing Nitrogen. If the generator has been
fitted with the optional Dry Air output, the same operating principle applies to the Air
output. The generator is protected from over pressurising and will experience a safety
valve offload if internal pressure reach above 145Psi.
Tubing Lengths
The diameter of the tubing which will be connected to the gas outlet
is important and is determined by the length of tubing required.
Failure to follow these recommendations could lead to pressure
between generator and application.
> 10 - 40 meters: Use 12/10 (12mm O/D, 10mm I/D) Tubing.
> 40 metres: Please contact Peak Scientific with the relevant distance
andwe
will calculate the flow resistance and the
tubing size required.
The imperial equivalents are: 12/10 = 1/2” O/D, 3/8” I/D.
Air input tubing is not supplied. 16mm OD, 12mm ID PTFE Tubing is recommended.
