vFPT – visual Fire Prevention Thermolabel

vFPT helps maintenance personnel understand the condition of the equipment, not only at the time of inspection,but can also see if the equipment has reached a certain temperature in the past. Unlike using a thermal imager, vFPT provides a clear picture of what has happened since the last check. These labels are extremely easy to install for any configuration of electrical equipment.

1-TEMPERATURE vFPT

The principle of operation is simple: at the activation temperature (70, 90 or 110 °C ) the white strips irreversibly change color to black.

Single-temperature vFPT thermal indicators detect overheating above the set maximum allowable temperature.

vFPT provides information on overheating occurred between 2 checks.
More effective way of tracking contact connections temperature than traditional visual inspection and infrared thermography (IRT).
Long strips allow to get 360° angle of observation.
Specially designed for installation on electrical equipment
10 years of validity period.
Single-temperature vFPT allows to determine the maximum exceeded temperature during operation of electrical equipment.
Control hard-to-reach or inaccessible elements for the thermal imager (MV switchgear, explosion-proof electrical equipment)

4-TEMPERATURES vFPT

Four vFPT temperature indicators allow to determine the maximum temperature to which overheating occurred and detect differences in heating of identical units (phases, motors, mechanical devices), allowing to understand the exact reason of the overheating.

Shows if the contacts is ok, concerning or emergency.
Detect defects at early stages.
4-temperatures vFPT allows you to understand not only if the contact has reached highest permissible temperature but also to see how defect evolves and understand the reasons of overheating
Reduce the risk of fires in electrical installations.
10 years of validity period
