Aerosol fire suppression that mounts like a circuit breaker. No pipes. No tanks. No annual recharge. Just reliable protection exactly where fire starts.
QRR0.02G/S — 20g agent, DIN rail clip
Unlike CO₂ or water systems, aerosol attacks fire at the molecular level — no oxygen displacement, no collateral water damage.
Ultra-fine potassium particles (0.1–10 microns) intercept combustion free radicals — H•, OH•, O• — terminating the chain reaction at the molecular level. Oxygen remains above 18%; safe for personnel.
Endothermic decomposition absorbs thermal energy from the flame zone, pulling local temperatures below ignition thresholds of common insulation materials (300–400°C).
Dense particulate cloud creates a physical barrier separating fuel from oxidizer, providing secondary suppression through flame structure disruption — all within 3 seconds of activation.

Recommended Quantity
Verify 35mm DIN rail (EN 60715 profile). Position the unit in the upper third of the enclosure for optimal downward aerosol dispersion.
Same clip mechanism as a circuit breaker. Verify 500mm clearance in front of the discharge nozzle.
Lay 1.5m heat-sensitive cable in a serpentine pattern covering all cable bundles and connection points. Secure every 150–200mm. Avoid bends >90°.
Connect 12–24VDC signal from fire alarm panel for remote activation. Dry contact output available for SCADA/BMS status monitoring.
| Nozzle → personnel access | ≥ 1,500 mm | Thermal safety during activation |
| Nozzle → protected equipment | ≥ 300 mm | Prevents thermal shock to components |
| Nozzle clearance (unobstructed) | ≥ 500 mm | Ensures proper aerosol dispersion |
| Side / rear clearances | ≥ 50 mm | Airflow for thermal management |
