Automatic Aerosol Spray Fire Extinguisher

The QRR series is a compact heat aerosol fire extinguishing device designed for small enclosed spaces where rapid local fire suppression is required. After activation, the solid aerosol-generating agent produces fine extinguishing aerosol particles that disperse through the protected space and help interrupt combustion through physical and chemical suppression mechanisms.

This Automatic Aerosol Spray Fire Extinguisher is suitable for electrical cabinets, control boxes, distribution panels, battery compartments, and other compact equipment enclosures. Its small body, optional appearance styles, and flexible installation methods make it practical for OEM equipment and retrofit fire protection projects.

• Compact enclosure protection: Designed for small protected spaces up to 0.4m3 or 0.8m3 depending on agent quantity.
• Fast aerosol discharge: Discharge time is no more than 6 seconds for rapid local suppression response.
• Wide working temperature range: Operates from -50°C to +90°C for demanding equipment environments.
• Long service life: Agent validity period is 10 years under proper storage and operating conditions.
• Flexible installation: Supports standard guide rail mounting or 3M adhesive installation.
• Multiple appearance styles: LT, TB, and LK housing options are available for different equipment layouts.
• Environment-conscious formula: The aerosol agent is designed to be non-toxic, non-corrosive, and free from ozone-layer depletion concerns.

This automatic aerosol fire suppression device is intended for compact enclosed spaces where electrical equipment, components, or stored energy systems require localized protection.

• Electrical control cabinets and distribution boxes
• Switchgear compartments and terminal boxes
• Battery cabinets, battery packs, and energy storage modules
• Communication equipment and telecom enclosures
• Automation equipment, machine control boxes, and OEM devices
• Small sealed or semi-sealed equipment spaces requiring localized fire suppression

• Install according to the technical specification and prepare proper safety measures during installation.
• Do not aim the discharge outlet toward people during installation or use.
• Check the matched activation device while the extinguishing device is in normal working condition.
• Before activation, confirm the discharge outlet is sealed and the protective cap has not fallen off.
• Do not install in environments exposed to rain, water splash, acid or alkali corrosion, or strongly corrosive gases.
• After device activation, clean the protected area within 24 hours and contact the supplier if technical support is required.
