Flame Detector

Flame detectors protect places where a fire can grow in seconds: fuel areas, furnaces, hydrogen and gas plants, and chemical or pharma units. Essatech supplies, installs and services flame detectors in Hyderabad and Visakhapatnam and links them to your alarm, fuel shut-off and suppression. Share your process details and we will visit the site before we quote.

What a flame detector does for your plant

A flame detector looks straight at the fire. Its optical sensors respond to the radiation a flame gives off, so it can sense a flame and send an alarm for the affected area in a fraction of a second, without waiting for smoke to rise or the air to heat. Outdoors, where wind carries smoke away, it keeps working because it does not depend on smoke. In industrial furnaces it responds faster and more accurately than smoke or heat detectors.

Three sensor types are common: ultraviolet (UV), infrared (IR) and UV/IR, which asks for both signals before it alarms. Our range includes industrial flame detectors, intelligent flame detectors and flame sensors, connected to a fire alarm control panel.

Where we install flame detectors

Petrochemical plants and industrial furnaces are the classic sites, but the same detectors protect many others:

  • Petrochemical and fuel handling areas
  • Industrial furnaces and burner lines
  • Hydrogen stations
  • Gas-fuelled cookers in large kitchens
  • Industrial heating and drying systems
  • Industrial gas turbines
  • Parking buildings and warehouses
  • Waste disposal facilities
  • Tall halls and other large public buildings

From alarm to fuel shut-off and suppression

The alarm does not have to stop at a hooter. When the detector is linked to the fuel supply controls, it can stop fuel pumping, and it can release the fire suppression system so the fire is dealt with at its source. We set these actions out in a cause-and-effect chart with your plant team before wiring.

Where flammable gas or vapour is present, hooters and call points must also suit the area. We supply flameproof hooters and flameproof manual call points for such sites.

What you get from Essatech

Every plant is different, so the work starts with a visit. It covers:

  • A site visit and a review of your process, fuels and hazards
  • Choice of UV, IR or UV/IR detectors and a coverage plan for each area
  • Supply, mounting and wiring
  • Links to your panel, fuel shut-off and suppression, as agreed
  • Commissioning with a test lamp made for the model
  • Maintenance and yearly checks, if you want them

For builders, architects, MEP consultants, corporates, industries, hospitals and defence

Industries are the main buyers: fuel bays, furnaces, hydrogen and gas areas and solvent stores. Builders and architects of process plants should place flame detectors at the design stage, with clear lines of sight and no pipework in the cone of vision. Commercial building owners need them only in plant and fuel areas, such as a generator yard, and hospital owners only in fuel and boiler areas, where approved equipment matters. MEP consultants can share the hazardous area drawings and we match detectors to the zones. Corporates need them only in fuel and generator areas. Defence sites, including Navy and Army depots and fuel installations, need approved flame detection in fuel areas, and we quote within their vendor-registration rules.

What decides the cost

Prices for flame detectors vary widely, from basic UV units to intelligent UV/IR models for hazardous areas, so a number without a site visit is a guess. These factors set the total:

  • Detector type: UV, IR, UV/IR or intelligent
  • Hazardous-area enclosure and approvals, where the site needs them
  • The number of detectors, since each one sees a cone and the area decides how many you need
  • Links to fuel shut-off and suppression, and the cable run to your panel

What to send us for a quote

Send us what you have through the quote page or on WhatsApp:

  • Plant layout or a sketch of the area to protect
  • The fuels, gases or solvents handled
  • Hazardous area classification, if you know it
  • What should happen on alarm: hooters, fuel shut-off, suppression
  • Make and model of your existing panel or PLC, if any

Reliability after installation

Oil film or dust on the lens blocks the view, so the window needs cleaning on a schedule that suits the site. Welding arcs, sunlight on shiny surfaces and hot machinery can trip single-sensor detectors, which is one reason UV/IR types are popular. Include flame detectors in your yearly fire safety audit or maintenance visit.

Flame detection for industry in Hyderabad and Visakhapatnam

Industrial clusters such as Jeedimetla, Patancheru and Bachupally in Hyderabad, and Gajuwaka, Autonagar and Parawada in Visakhapatnam, have fuel, solvent and furnace areas that need fast detection. Contact our offices to book a site visit.

Talk to our local team

Share your location, type of building and what you need. We will suggest the right equipment and explain installation and maintenance.

Common questions

Which flame detector do I need: UV, IR or UV/IR?

It depends on your fuel and surroundings. UV/IR needs both signals, which cuts false alarms from welding and sunlight. We recommend a type after a site visit.

Is the detector approved for my hazardous area?

Models differ. Check the approval of the model quoted, such as ATEX or PESO, against your site classification. Tell us the classification and we will quote a suitable enclosure.

How much does a flame detection system cost?

It depends on detector type, approvals, the number needed and the links to shut-off or suppression. We quote in writing after a site visit.

Can the alarm shut off fuel and release suppression?

Yes. Linked to the fuel supply controls, it can stop fuel pumping and activate the fire suppression system.

Will welding or sunlight set it off?

It can with a single-sensor detector. UV/IR types and careful placement reduce the risk, and we check for welding bays and bright windows on the visit.

Do you install and maintain, or only supply?

We supply, install, commission and maintain flame detection, and link it to your alarm and plant controls.
