Dräger Flame 2700 (Multi-IR) Flame Detector

Overview

The Dräger Flame 2700, designated Multi-IR, is a multichannel infrared flame detector that recognises both hydrocarbon fires and hydrogen fires. Hydrogen burns with an almost invisible flame and gives off little of the carbon dioxide emission that ordinary hydrocarbon IR detectors rely on, so a detector that explicitly lists hydrogen sensitivity is valuable for electrolyser, refuelling and chemical sites. Dräger quotes a response of about 5 seconds, with gasoline fires detected out to 65 metres and hydrogen flames out to 38 metres in the sensitivity table, measured on a 0.1 square metre pan fire or a defined plume fire.

Across Oman and the wider GCC, Seven Star LLC supplies the Dräger Flame 2700 on request, backed by engineers based in Muscat. We help refineries, petrochemical plants, gas processing sites and emerging hydrogen projects choose detector variants, accessories and mounting hardware that fit their layout.

Multichannel IR Detection in the Dräger Flame 2700

Instead of looking at one narrow infrared band, the Dräger Flame 2700 evaluates several channels between 2 and 5 micrometres. This wider spectral window is what lets the detector respond to hydrogen as well as hydrocarbon flames, and cross-checking the channels is how multi-IR detectors in general separate genuine fires from interference. Dräger reports that the 2700 ignores nuisance sources like arc welding and hot CO2 plumes, and its sensitive optics avoid reacting to fires beyond the monitored zone.

Coverage angle depends on the fuel: 80 degrees horizontally and 80 degrees vertically for gasoline, and 70 degrees horizontally with 80 degrees vertically for hydrogen. The sensitivity table also lists ammonia at 18 metres and silane at 2 metres for a smaller plume fire, so engineers working with unusual fuels can check coverage directly in the data sheet.

Construction and Diagnostics

The body is cast in SS316L stainless steel and weighs 2.8 kg. Ingress protection reaches IP66 and IP67 (NEMA 250 6P), and wiring enters through a pair of NPT or metric threaded ports. On the Dräger Flame 2700, a heated window protects the optics against icing and fogging, which matters for cold or humid installations and for sites with large day and night temperature swings.

The detector runs a Built-in-Test routine on its electronics and optics without operator action, and a manual test can be started too. A three-colour LED on the front face reports the state: green means healthy, yellow means a fault, and red means fire. To connect to a plant system, the detector offers HART, an RS-485 Modbus link, stepped current output and relays, powered from 24 V DC.

Key Features

The Dräger Flame 2700 provides these core capabilities:

• Multi-IR sensing of hydrocarbon and hydrogen-based fires in the 2 to 5 micrometre range.
• Response in around 5 seconds, with gasoline fires detected to 65 metres.
• Hydrogen flame detection to 38 metres for a plume fire under the stated test conditions.
• SIL 2 capability confirmed by a TUEV certificate.
• Rejection of welding arcs, hot CO2 plumes and similar nuisance sources.
• A heated viewing window and a self-test that can run automatically or on demand.
• HART and Modbus over RS-485, a stepped current loop and three relays.
• Service in ambient temperatures from -55 °C up to +75 °C.

Industrial Applications

Where a plant handles both oil-derived fuels and hydrogen, a single detector family such as the Dräger Flame 2700 reduces design complexity. The Dräger Flame 2700 suits hydrogen production and compression, ammonia and chemical processing, refinery hydrotreating units, gas turbine halls and fuel storage, alongside classic hydrocarbon hazards such as diesel, jet fuel, alcohols, methane and LPG, all of which appear in the published sensitivity data.

Contractors and plant owners from Muscat to the Sohar and Salalah economic zones can rely on Seven Star LLC for layout review, accessory selection and spare parts planning. Because Oman is developing green hydrogen and ammonia projects, the hydrogen capability of the Dräger Flame 2700 is a practical reason to specify it for new facilities, while the same body style serves established oil and gas sites.
