Description
The 5kg CO2 Fire Extinguisher Hydrostatic Testing & Refilling Service restores discharged, partially used, or due-for-inspection portable extinguishers back to 100% operational readiness. Carbon dioxide extinguishers store high-purity liquid CO2 under extreme pressures (55 to 60 bar at normal ambient temperatures). Over time, repeated thermal cycles, mechanical stress, or seal degradation can lead to pressure loss or structural shell fatigue.
Features
- Civil Defense & NFPA 10 Compliant: Guarantees full adherence to building code standards for commercial offices, server rooms, and industrial properties.
- High-Pressure Structural Verification: Hydrostatic testing at 250 bar ensures maximum pressure containment safety and operator protection.
- Precision Digital Scale Metering: Automated gravimetric liquid transfer guarantees the exact 5.0 kg charge needed for optimal discharge duration and flame knockdown power.
- Complete Seal Replacement: Replaces mandatory internal valve seals and pressure relief burst discs to eliminate micro-leaks during prolonged storage.
