The AQRS is an in-panel, tube-based micro-environment suppression system designed for high-risk enclosed spaces such as electrical panels, server racks, MDBs, and industrial machinery — areas where fires can go undetected until they become too large to control.

The system uses heat-sensitive pneumatic tubing for detection, routed across the protected area. On contact with fire, the tube ruptures at 80°-90°C, triggering discharge of the clean gas-based extinguishing agent directly onto the fire — with no clean-up required, no power supply needed, and safe use on live electrical equipment.

Key Features:

• Effective on Class A, B, C fires and electrical fires
• Self-actuated, no power supply required
• Electronics-friendly, non-conductive, no residue after discharge
• 24-hour automatic protection, no false activations
• Single cylinder can protect multiple enclosures via additional tubing

Applications: Electrical Panels & Cabinets, Switching Areas, Server Racks, Printing Press, Mobile Towers, Diagnostic Machines, UPS Rooms

Key Specs:

• Cylinder Material: Mild Steel / Stainless Steel
• System Pressure (20°C): 14 bar | Test Pressure: 35 bar
• Working Temperature Range: -20°C to +70°C
• Extinguishing Agent: HFC-227ea (C₃HF₇) | Propelling Gas: Nitrogen (N₂)
• Approvals: UL Listed / FM Approved | EPA: Acceptable

Configurations:

• Direct System: Tube acts as both detection and delivery — ruptures at the fire location and releases agent directly onto it.
• Indirect System: Tube acts as detection only — a separate steel conduit with nozzles delivers the agent once triggered.

Product Range:

Available in Mild Steel or Stainless Steel cylinders (model codes FGQRH-[qty]-M/S-D/I). Fire detecting tubes are UL-recognized, red (RAL3000), rated -40°C to +80°C, with a minimum 8-year service life.
