Flame Detectors

Crowcon offers a range of infra-red (IR) and ultra-violet (UV) based flame detectors for quickly detecting flames at a distance. Depending on model, this includes a variety of gas and fuel fires including those generated from hydrocarbons, hydrogen, metals, inorganic and hydroxyl sources.

Overview

The 40/40 series operate in the harshest environmental conditions and are self-contained, stand-alone devices designed for direct connection to control and alarm systems or automatic fire-extinguishing systems.

40/40I Triple IR (IR3) Flame Detector

The 40/40I Triple IR (IR3) Flame Detector detects fuel and gas fires at long distances with the highest immunity to false alarms. The 40/40I IR3 can detect a 1ft² (0.1 m²) gasoline / heptane pan fire at 215 ft (65 m) in less than 5 seconds.

40/40M Multi IR Flame Detector

The 40/40M Multi IR Flame Detector is specifically designed for detection of hydrocarbon and hydrogen flames. It detects hydrocarbon-based fuel and gas fires at long distances with the highest immunity to false alarms.

40/40 Series UV/IR Flame Detectors

There are two versions of 40/40 Series UV / IR Flame Detectors:

Model 40/40L (& LB) detects hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires.
Model 40/40L4 (& L4B) is identical to the 40/40L except that the IR sensor works at a wavelength of 4.5µm and is only suitable for hydrocarbon-based fires.

40/40UV Flame Detector

The 40/40UV Flame Detector design is the most durable and weather resistant UV flame detector currently on the market.

40/40R Single IR Flame Detector

The 40/40R Single IR Flame Detector detects hydrocarbon-based fuel and gas fires using advanced flame analysis tools.

20/20 Range

The 20/20 range includes Mini IR3 and Mini UV/IR detectors which offer a lower cost, lower power, compact design in a general purpose (non-Ex approved) format. The 20/20MI IR3 is also available as ATEX intrinsically safe approved.
