QRR0.05GW/SMJ Condensed Aerosol Fire Suppression Unit

The QRR0.05GW/SMJ Condensed Aerosol Fire Suppression Unit is a high-efficiency, environmentally friendly fire protection device designed for both total flooding and local application in enclosed or semi-enclosed spaces.

When a fire occurs, the thermal activation line is triggered by flame, initiating the aerosol-generating compound. The system produces a dense, nano-scale aerosol cloud that is released into the protected area after cooling, effectively suppressing fire through both physical (cooling and oxygen displacement) and chemical inhibition mechanisms.

The unit is waterproof and moisture-resistant, making it suitable for a wide range of operating environments.

Key Features

  • Supports total flooding or localized fire protection
  • High-efficiency aerosol fire suppression technology
  • Environmentally friendly and non-toxic agent
  • No residue and non-corrosive to equipment
  • Waterproof and humidity-resistant design
  • Fast response with thermal or flame activation
  • Suitable for harsh operating environments

Applications

  • Electrical cabinets
  • Industrial equipment enclosures
  • Battery compartments
  • Control panels
  • Machinery rooms
  • Other enclosed or semi-enclosed fire-risk areas

How It Works

When exposed to flame or high temperature, the thermal activation line ignites the aerosol generator. The system releases a high-density aerosol cloud, which is cooled and evenly distributed into the protected area.

The fire is suppressed through:

  • Oxygen displacement (physical effect)
  • Heat absorption and cooling
  • Chemical chain reaction inhibition
