Industries & Applications

Protectowire Linear Heat Detectors can identify the location of an overheat or fire condition anywhere in a cable tray. The detector may be economically applied to monitor each tier of cables and is adaptable to all cable tray types such as a ladder, trough, solid-bottom, channel, cable bus duct, and tubing raceway. In most cases, the detector follows the vertical and horizontal runs and may be placed in direct contact with the cables.

The major risks of fire in conveyor installations are overheated bearings, combustible materials being conveyed, and in the case of belt conveyors, the belt itself. Once a fire is ignited it can spread quickly along the length of the conveyor and be extremely difficult to extinguish. The detector is typically installed directly over the conveyor or on either side of the belt near the roller bearings. Protectowire Systems can be designed to protect all types of conveyors.

In cooling towers, wooden framework, decking, plastic impregnated fiberglass supports and dividers are all combustible hazards. Protectowire Linear Heat Detectors provide a reliable system for activating deluge sprinklers. The detector is typically installed around the fan motor on the fan deck and circles the perimeter of the fan cylinder base just beneath the deck.

Protectowire CTI Series Linear Heat Detectors’ robust design is the ideal choice for solar panel installations. Unlike traditional spot heat detectors, the CTI Series Linear Heat Detector can be placed directly onto the underside of solar panels to provide immediate proximity detection. Since solar panels are installed outdoors, this means they are subjected to hail, high winds, lightning, ice, bird nests, rodents, and other natural forces that can damage the panels or their components. The CTI Series Linear Heat Detector will only issue an alarm condition when its fixed temperature has been reached.

Protectowire Linear Heat Detectors may be easily installed inside equipment to follow cable raceways, wiring harnesses or placed in direct contact with components or areas that are subject to overheat and fire. The detector may be used anywhere ambient temperatures do not exceed its installed temperature rating. Nonmetallic cable straps are used to fasten the wire during installation. Installation time and expense are greatly reduced when compared to spot-type heat detectors.

Transformer fires often occur because of arcing due to the deterioration of insulation. Fires are also caused by lightning or dirty insulators on the tank. Protectowire Linear Heat Detectors provide a simple and reliable solution. The detector can be easily installed adjacent to or directly on all types of transformers to provide early detection of any overheat condition.
