Strategic partners:

The Protectowire Company develops and manufactures linear heat detection systems for transportation, industrial facilities, infrastructure, and other special-hazard applications. Founded in 1938 following the invention of its original heat-sensitive detector, Protectowire has spent more than eight decades advancing technologies that identify abnormal heat along extended areas and within difficult-to-access spaces.

Unlike individual spot detectors, Protectowire Linear Heat Detectors provide continuous detection along the full length of the sensing cable. Their flexible construction allows them to be routed through engine compartments, equipment enclosures, battery areas, and other confined locations where fire may develop outside the range of conventional detection devices. Products are engineered to withstand vibration, abrasion, automotive fluids, solvents, and challenging environmental conditions commonly encountered in transportation applications.

Protectowire designs, engineers, manufactures, and tests its products under an ISO 9001:2015-certified quality-management system. Its portfolio includes digital and fiber-optic linear heat detectors, interface modules, control panels, thermal cameras, flame detectors, and related fire-protection equipment.

Within the Troman partner network, Protectowire supplies a durable and reliable layer of proximity heat detection. Its sensing technology helps identify developing thermal conditions at their source, supporting faster alerts and earlier intervention in engine compartments, battery enclosures, and other high-risk vehicle areas.

Troman Industries is the exclusive North America distributor for Protectowire linear heat detection systems products.
