Applications
Conditions of use
● The resistance heaters are controlled by a thermostat or a hygrostat.
● The enclosure must be sealed to prevent the entry of air from the outside.
Relative humidity (%)
Dew point temperature
The dew point temperature is the minimum temperature that can be reached before
condensation begins to form.
Example:
Ambient temperature = 25 °C.
Relative humidity = 50 %.
A temperature of more than 14 °C must be guaranteed inside the enclosure.
Installation tips
● Install several heaters according to the desired power level at the bottom of the
enclosure.
● Respect a safety area of at least 10 cm around the device.
● Do not install any bulky devices above the heater, since this could reduce the
effect of natural convection.
● Do not install any components that are particularly sensitive to heat directly above
a heater.
● If several heaters are used, they must be installed in parallel. Serial installation is
not an option.
● The heater must be installed vertically to ensure optimum convection.
