Integrated proportional pressure regulators ensure controlled and precise filling, preventing overpressure scenarios and ensuring operator safety.

3. Advanced monitoring and control

Features an HMI (Human-Machine Interface) on the front panel for seamless operation in auto mode, enabling easy monitoring and adjustment of parameters. Includes a pressure transmitter and Bourdon gauge for accurate real-time pressure readings.

4. Enhanced filtration

The pneumatic lines are equipped with 5-micron filters to remove impurities, ensuring the purity and safety of the gases during filling.

5. Safety and emergency features

Designed with an emergency stop button located on the front panel to instantly halt the system during critical conditions, ensuring operator and system safety.

6. Ease of use

Simple start (green button) and stop (red button) operations for user-friendly control. Infinitely variable cycling speed allows precise control of the flow rate.

7. Low maintenance and durability

Self-lubricating pump seals eliminate the need for external air-line lubrication, reducing operational complexity. Compact, robust, and reliable construction ensures long service life with minimal downtime.
