Pyrotech Electronics Pvt. Ltd., a leading Indian manufacturer of industrial safety equipment, specialises in PESO-certified UV/IR flame detectors for hazardous areas. These advanced fire detection systems minimise false alarms in hydrogen plants, oil & gas refineries, and petrochemical facilities.

What is UV/IR Flame Detection Technology?
UV/IR flame detectors use dual-spectrum ultraviolet (UV) and infrared (IR) sensors to identify flames accurately in real time. This technology detects hydrogen flames within milliseconds while ignoring sources like sunlight, welding arcs, or hot surfaces. Ideal for explosion-proof Zone 1 and Zone 2 environments, PESO-certified UV/IR detectors ensure compliance with Indian hazardous area regulations.

Key Benefits of UV/IR Flame Detectors for Hydrogen Safety

  • Rapid detection of invisible hydrogen fires, preventing escalation in high-risk areas.
  • Significant false alarm reduction through dual UV/IR signal verification.
  • Wide coverage with fewer units needed for large industrial spaces.
  • Enhanced operational continuity by avoiding costly shutdowns in refineries and chemical plants.

    These features make PESO-certified UV/IR flame detectors essential for industrial fire safety in hydrogen-hazardous areas.

How Pyrotech UV/IR Detectors Minimise Fire Risks
Pyrotech's PESO-approved UV/IR flame detectors excel in hydrogen storage, LNG terminals, and power plants by filtering non-fire radiation. They trigger alarms only on confirmed flames, integrating with fire suppression systems for quick response. Rugged designs withstand harsh conditions like high heat, dust, and corrosion in petrochemical settings.



Pyrotech Technologies Pvt. Ltd. is officially PESO-approved for its UV/IR flame detectors, as confirmed by the Petroleum and Explosives Safety Organisation (PESO) under the Government of India. The approval No. A/P/HQ/RJ/104/5547 (P658297) certifies Model No. Ex ib IIC T4 Gb for safe use in hazardous areas per Gas Cylinder Rules 2022. This ensures reliable, explosion-proof performance in hydrogen and industrial environments.

Industries Benefiting from PESO UV/IR Flame Detectors

  • Hydrogen production and storage facilities
  • Oil & gas refineries and petrochemical plants
  • LNG terminals and fuel handling stations
  • Chemical processing and fertilizer plants
  • Power generation and battery manufacturing units

These sectors rely on UV/IR technology for reliable flame detection in hazardous environments.
