QRR0.3GW/SMJ Condensed Aerosol Fire Suppression Unit

The QRR0.3GW/SMJ Condensed Aerosol Fire Suppression Unit is a high-efficiency and environmentally friendly fire protection solution designed for enclosed and semi-enclosed spaces.

This S-type aerosol system rapidly releases a dense aerosol cloud upon activation, effectively interrupting the combustion chain reaction and suppressing fire at an early stage.

Featuring pressure-free storage, high safety, and residue-free discharge, it is especially suitable for protecting electrical and electronic equipment without causing damage.
