Heating elements
The resistors prevent condensation, corrosion and superficial leakage currents.
They maintain a positive temperature in the enclosures when external temperatures
drop very low.
Install heaters according to the desired power level at the bottom of the enclosure,
respect a safety area of a least 10 cm around the device.
Vertical installation is recommended to ensure optimum convection.
The resistance heaters are equipped with a PTC - type sensor (positive temperature
coefficient). Thanks to these heaters, the surface temperature stabilises at 75 °C
when the ambient is at -5 °C.

Regulating
Used to control the temperature inside electrical switchboards in conjunction with
heating resistors and fans.
This thermostat can control the activation of a fan and a heater and regulate their
temperature independently.
Double adjustable thermostat
Double temperature control with a resistance heater and a fan with separate
operation
