If an enclosure has been installed outdoors, frost and condensation can pose a danger to the electronics. Yet condensation can also arise in indoor enclosures.
This can be prevented by an effective heating system. A heater generates a minimum operating temperature in the enclosure and helps protect the electronics from frost and condensation even when the enclosure is switched off (for instance, at night).
This white paper will help you calculate the heating output you require and choose the right heater.
