The 20/20MI is an economical and compact Triple IR (IR3) Flame Detector with the highest immunity to false alarms, in a rugged stainless steel housing.

There are two versions to choose from:

20/20-MI-1 Triple IR (Standard Range 10-40 m) – EN-54-10
20/20-MI-3 Triple IR (Short Range 2.5-10 m) – FM

With the highest immunity to false alarms, the Mini-IR3 has applications in a wide range of industrial and commercial facilities, where the threat of accidental fire involves hydrocarbon fuels such as gasoline, kerosene, diesel fuel, aviation jet fuels like JP-4, JP-5, JP-8, hydraulic fluids, paints and solvents, monomers and polymers like ethylene and polyethylene, natural gas (LNG), town gas and liquefied petroleum gas (LPG), hydrocarbon gases
like methane, ethane, propane, butane, acetylene, propylene, etc.

The patented Triple IR design also offers 3-4 times the detection distance of any conventional IR or UV/IR Detector. This detector is packaged in a compact, lightweight housing for easy installation and where space is at a premium. It is specially designed as a general-purpose flame detector for industrial applications to withstand “harsh” environmental conditions, including extreme temperatures, high humidity and vibrations.
