Automatic Pressure Control Fire Suppression Agent Charging Unit for Multiple Cylinder Sizes

Perfluorohexanone (Novec 1230) Fire Extinguishing Agent Filling Equipment

Product Overview

Perfluorohexanone (Novec 1230) fire extinguishing agent filling equipment is a professional, high-precision, and safe filling system designed for clean agent fire suppression systems. This automatic fire suppression system refilling unit ensures accurate transfer of Novec 1230 gas and other extinguishing agents into storage cylinders, maintaining optimal performance of your fire system.

The equipment is widely used by fire protection engineering companies, system integrators, data centers, power plants, petrochemical facilities, telecom rooms, and industrial plants. The system integrates nitrogen pressure reduction, a filling pressure alarm, a vacuum pumping unit, and a reserved weight alarm interface. It supports multiple cylinder sizes to ensure sealed, stable, and accurate filling performance.

Filling Operation Procedure

Step 1 – Initial Setup and Nitrogen Filling

After the cylinder is valved, move it to the filling room. Secure the cylinder and connect the piping between the cylinder and the filling station. Adjust the electric contact pressure gauge alarm and the pressure reducing valve outlet pressure. Open the cylinder container valve, then slowly open the nitrogen valve to fill with nitrogen. Control the pressure increase rate to no more than 1 MPa per minute until the pressure reaches the specified maximum operating pressure. Close the cylinder container valve and move the cylinder to the pressure test room for a cylinder seal test.

Step 2 – Vacuum Evacuation

After the cylinder passes the seal test, move it to the platform scale in the filling room. Secure the cylinder and connect the piping. Open the cylinder container valve, then open the pressure relief valve to relieve pressure. After pressure relief is complete, activate the vacuum function and open the vacuum valve. Start the vacuum pump to evacuate the cylinder. When the pressure gauge approaches -0.09 MPa and stabilizes, close the vacuum valve and stop the vacuum pump.

Step 3 – Dew Point Control

Adjust the electric contact pressure gauge and pressure relief valve outlet pressure to 1 MPa. Open the nitrogen valve and filling valve to fill the cylinder with nitrogen, displacing any residual gas. Slowly adjust the nitrogen pressure to 1 MPa. Once complete, close both valves. Use a dew point meter to check the gas dew point in the cylinder. Maintain it within 10 ppm. If the dew point exceeds 10 ppm, repeat evacuation and nitrogen replacement until the requirement is met before proceeding to agent filling.

Step 4 – Agent Filling

Once the dew point meets the required level, open the pressure relief valve. After pressure relief is complete, close the relief valve and evacuate the cylinder again. Then close the vacuum valve.

Tare the cylinder weight on the scale, then set the desired agent weight according to the production order or specifications. Open the agent valve and filling valve to fill the cylinder. Simultaneously, open the pressure gauge on the cylinder to relieve pressure. When the pressure gauge begins releasing the extinguishing agent, stop venting and securely close the gauge.

When the agent reaches the set weight, the filling station will sound an over-weight alarm, indicating completion and automatically shutting off the line. Then manually close the agent valve.

Filling Specifications:

• Maintain a filling rate of no more than 3 kg per second

• Filling volume tolerance: +0.5 kg / -0 kg (e.g., for a 60 kg order, control filling between 60 and 60.5 kg)

Step 5 – Nitrogen Pressurization

Adjust the pressure reducing valve outlet pressure according to the required filling pressure for the specific temperature conditions. Set the electric contact pressure gauge alarm. Slowly pressurize the cylinder by opening the nitrogen valve and filling valve. Control the pressurization rate to no more than 1 MPa per minute.

When the filling pressure reaches the specified level, close both valves. Then close the cylinder container valve and open the pressure relief valve to relieve pressure in the pipeline. After pressure relief is complete, disconnect the pipeline from the cylinder container valve. Filling is now complete.

Step 6 – Post-Filling Inspection and Storage

Allow the filled cylinder to rest for 1 hour. Verify the agent weight and pressure in the cylinder. If there is no pressure loss or weight loss, move the cylinder to the semi-finished product area for storage.

After storage for 24 hours or more, recheck the pressure before shipment. If the pressure is too low, re-pressurize to meet the corresponding requirements.

Additional Note: If the pressure in the agent tank is insufficient to allow the agent to be discharged, the tank requires pressurization. The added pressure shall not exceed 2 MPa.
