- Annual Inspections: Full physical check and updated certification tags.
- 6-Year Internal Maintenance: Required breakdown and internal inspection of dry chemical units.
- 12-Year Hydrostatic Testing: Pressure testing cylinders to ensure structural integrity.
- Mobile Recharging: Fast, on-site recharging after a discharge or pressure loss.
