5.2.4 Sieve Bed Pressure Gauge
Each unit is equipped with two sieve bed towers. At the top of each tower, there’s a pressure gauge to
monitor the pressure changes in the beds throughout the cycle. These are used to help indicate if there’s any
problem with the air going to each bed.
5.2.5 Tank Pressure Indicator
The PLC comes standard with a pressure indicator to display the current pressure inside the Nitrogen Storage
Tank. Looking at the above
Figure 1 , the tank pressure can be view on the left side on the main screen.
5.2.6 Inlet Air Pressure Regulator Gauge
All tank and cabinet model units will come standard with the air pressure regulators inside the units. Most
skid model systems will come standard with the air pressure regulators inside the cabinet as well. Some of the
larger units will have the regulator install outside the cabinet. The regulator,
Figure 6
, will have a 2” back
mount 0-160 psi gauge.
Figure 6: Filters/Air Regulator Set
The regulator will come factory set between 100-150 psi based on the customer predetermined design criteria.
It is set with 150 psi on the front side (pressure coming into the regulator). Based on customer site conditions,
it may be necessary to adjust the regulator to set the pressure to the correct setting. To do so, use the provided
2” pressure gauge on the regulator to set the incoming air pressure based on the site conditions. Depending on
the type of regulator you have, you’ll either loosen a turn knob or a nut slightly to allow you to adjust the
pressure. To increase the pressure, rotate the knob clockwise; to decrease the pressure, rotate the knob
counter clockwise.
**Note – pressure should be set as close to the top of each bed swings as possible. To do this, slowly
adjust the pressure and monitor the air in gauge pressure until the bed swings. Right before the bed
swings, note the air in pressure and use that as your incoming air pressure setting. At the instance of
the swing, the pressure will overshoot up to 15%. This pressure should be ignored and not used as your
incoming air pressure setting. Also note that the output pressure of the compressor limits the
maximum pressure available to the nitrogen generator.
