Touch-Safe Semiconductor Heater – Enclosure Heater for Electrical & Electronic Components

The Touch-Safe Heater (Semiconductor) is designed for reliable heating inside enclosures containing electrical and electronic components. Also known as an enclosure heater, it prevents condensation, ensures consistent operating temperatures, and protects sensitive equipment from moisture and cold.

Thanks to its low surface temperature and clip fixing system, this heater is quick and safe to install. Its compact size makes it ideal for applications where space is limited, while the double-insulated plastic housing enhances safety in continuous operation.

Natural convection airflow ensures efficient heat distribution inside the enclosure, while maintaining cool-to-touch surfaces on the accessible sides. For added flexibility, the heater can be directly connected to our full range of thermostats and hygrostats (NTL 152), or supplied in a plug-in thermostat version for simple, tool-free installation.
