Mobile Nitrogen Charging Unit

Model Explanation
MNC25P
1       2     3
1. Product code: MNC means mobile nitrogen charging unit
2. Pressure grade: 25Mpa, 35Mpa, 42Mpa
3. Reversing method: Pilot operated hydraulic control

Brief Introduction
As indicated by its name, the mobile nitrogen charging unit is especially designed to fill nitrogen gas into bladder accumulator, piston accumulator, diaphragm accumulator and other high pressure vessels. Our product has a maximum charging pressure of 42Mpa, and it shows the advantage of simple operation as well as excellent mobility.

Working Principle
This nitrogen charging unit mainly consists of hydraulic devices, pneumatic devices and electrical devices. When fluid under pressure flows into the pressurizing unit (i.e. piston accumulator) via directional control valve, the piston will be driven by the fluid to move upward or downward, thus compressing nitrogen gas inside the upper or lower chamber of pressurizing unit. Then, the pressurized nitrogen is filled into accumulator or other high pressure vessel through a non-return valve. The piston moves in a reciprocating way until desired gas pressure is achieved.
