The Tech Inc. Pressurisation, Purge and Command-Gas Panel regulates and switches high-pressure helium and nitrogen for three duties at launch pads and engine test stands: pressurising propellant tanks to drive the propellant out, purging lines clean, and supplying the command gas that operates pneumatic valves. The TI-PCP takes gas from storage at up to 400 bar and delivers each circuit at its own controlled pressure, with remote operation from the control room.
Main components
- Inlet filtration and isolation from the storage skid
- Pressure-reducing regulators for the pressurisation, purge and command-gas circuits
- Solenoid valves for remote switching of each circuit
- Relief valves and vents on every regulated circuit
- Pressure transmitters and local gauges
- Tubing and fittings on a panel or open frame
- PLC or hard-wired interface to the pad or test-stand control system
Applications: propellant tank pressurisation, purge of propellant and engine lines, command gas to pneumatic valves, and gas supply panels at launch pads and engine test stands.
