The equipment allows the charge and refill of any nitrogen user at the low and high pressure, with the possibility to exceed the bottle pressure up to 300 bar.
The Nitrogen bottle handling booster cart has been designed in order to give the possibility to perform the nitrogen charge and the refill at low and high pressure also when the pressure inside the bottles is lower than the pressure required.
The use of pressure booster, driven by nitrogen or by compressed air, allows the delivery pressure up to 300 bar.
The cart has been designed in order to grant a great stability when is requested to carry and operate two 40 liters or 50 liters nitrogen bottles, in addition, safety device has been provided to make safe the bottles load on the cart. All the controls and instruments are located on ergonomic instrument panel and all the actions can be carried out with having all the instruments and controls in view.
The charging and filling activities can be monitored by four pressure gauges (Ø 100mm):
- One pressure gauge (0-250 bar, precision class 1,0) on the feeding line. This pressure gauge indicates the pressure inside the bottles when the shut-off valves are open. A pressure regulator downstream the gauge allows the user to adjust the feeding pressure (when the booster is excluded) or adjust the nitrogen driving and the feeding pressure to the booster.
- One pressure gauge (0-300bar, precision class 1,0) on the high-pressure delivery line. This pressure gauge works both when the nitrogen is supplied directly from the bottles or the nitrogen in pressure is supplied by the booster.
- One pressure gauge (0-25 bar, precision class 1,0) on the low-pressure delivery line. A max pressure valve is installed downstream the pressure gauge (preset 20 bar).
- One pressure gauge (0-10 bar, precision class 1,0) upstream the booster on the driving line. This pressure gauge gives the indication of the booster driving pressure (nitrogen or shop air). Upstream the booster one pressure regulator is provided to adjust the feeding nitrogen/air pressure.
