GTE / Adicos Hotspot- & Flame Detectors
Compact infrared T-array detectors, which contactless detect a heat source at a distance of a few meters using infrared radiation. Depending on the distance to the objects to be monitored, these hotspot detectors can detect heat sources that are hotter than, for example, 60 °C or 70 °C. Therefore, heat generation in a waste heap or on a conveyor belt can be detected at an early stage, provided the heat is present on the surface. The hot spot detectors can also detect open fire and are therefore very suitable as a replacement for conventional systems, which only detect open fire.

The HOTSPOT-X0 is the first IR-fire detector that has been approved worldwide for the potentially explosive gas atmospheres of zones 0 to 2. The innovative thermal camera allows for early fire detection in chemical parks and gas-fired power stations, as well as in all other areas in which potentially explosive gas atmospheres can occur.
The Hotspot-X0 detects excess temperatures
and flames and supports several alarm zones by means of independent alarm parameters – this ensures the best possible adaptation of the detectors to the particular application. Its compact design allows its use also within confined spaces. HOTSPOT-X0 thermal cameras can directly be integrated in the fire alarm bus of central fire alarm systems.
Monitoring of transported material
When transporting flammable goods on conveying systems in power stations, transshipment terminals or recycling plants, there is always a risk of spreading of hot spots. If sparks are introduced from damaged grinders or if material is delivered which is already inflamed, a reliable detection is to be carried out before storage. For that purpose, the use of infrared detector arrays is a proven method. Thanks to the quick speed of response combined with the high sensitivity and local resolution, near-surface smouldering can be detected.
The possible covering of a smouldering by non-burning material is to be taken into account. Although in such cases it is possible that the material positioned above consequently heats as well in such a way that a detection becomes possible on the visible surface, the detectors can be arranged in such a way that, for instance, the discharge parabola of a chute is monitored in order to ensure a reliable detection for the other cases as well. An alternative which is less prone to contamination is the positioning of two detectors immediately in front of and behind the chute. This arrangement utilises the fact that a hotspot which is probably hidden on the first belt is at least partly visible on the surface after transfer and therefore becomes detectable.
Monitoring of plant damages
For early detection of plant damages, e.g. on conveying system in rooms with high ceilings, strong ventilation or outdoors, infrared detector arrays are used. In doing so, the focus in on damage scenarios like overheating drive rollers, motor overheating and dragging chains and belts. Thanks to the appropriate parameterisation of the individual array fields, the detector triggers in good time prior to an imminent plant overheating and, in addition, alerts in a differentiated manner in case of fire in the surroundings of the plant or if smouldering material is transported.
In any event however, it must be taken into account that only those objects are monitored which have “visual contact” to the detector. In case of large shadowing surfaces, detectors with different viewing angles should be installed where necessary.
