This high-end ATEX box heater is designed to allow some appliances to operate in extremely low temperatures.

It is available with, or without a built-in junction box. The TEF9207 series offers up to 14 different references, for a power of 100W to 1000W for the larger ATEX boxes. It is also possible to opt for a version with built-in thermostat, which starts the ATEX box heating as soon as the temperature reaches -5oC.
