DIN Rail Aerosol Fire Suppression Device | Automatic Heat Extinguisher QRR0.01G/S

The QRRO.01G/S Heat Aerosol Fire Extinguishing Device is an automatic, non-pressurized fire suppression solution engineered for electrical enclosures, battery energy storage systems (BESS), EV charging stations, solar inverters and industrial equipment cabinets. Using advanced S-type aerosol chemistry, it activates automatically at 170°C — no power supply, no detection network, no external trigger required — making it ideal for remote, unmanned and hard-to-reach sites.

Certified to EN 15276-1:2019 with CE marking, this maintenance-free device provides a 10-year service life and operates reliably from -50°C to +90°C. On activation it discharges clean, non-corrosive, residue-free aerosol that suppresses Class A/B/C and electrical fires within seconds, protecting sensitive electronics without secondary damage. The compact L-shaped housing fits easily into confined spaces inside cabinets, battery packs and vehicle compartments.

Feature

170 ° C automatic temperature sensing start - no need for power supply and detection linkage, can independently extinguish fire even in the event of power failure

Non pressure storage - no high-pressure gas cylinder, no pipeline network, no leakage risk

Maintenance free 10-year lifespan - zero maintenance after installation, low overall usage cost

S-type clean fire extinguishing agent - low smoke, non corrosive, no residue, does not damage electronic components

Quickly extinguish the fire in seconds - fully submerged extinguishing the initial fire and suppressing the spread of thermal runaway

Wide temperature range -50 ° C~+90 ° C, suitable for outdoor extreme environments
