Walk-in Nitrogen Pressure Boosters are suitable for pressurizing nitrogen in hydraulic bladder accumulators, hydraulic piston accumulators, hydraulic diaphragm accumulators, and other high-pressure vessels. The pressure boost for nitrogen is 65MPa. Typically, when nitrogen cylinders are directly used to fill accumulators, the inflation pressure is equal to the cylinder pressure. If the required pre-filled nitrogen pressure in the accumulator exceeds the cylinder pressure, direct inflation is not sufficient to meet the accumulator's requirements. The MCE type nitrogen filling vehicle can fulfill the nitrogen filling needs for high-pressure accumulators.
