Anti-condensation is designed for heating small rooms, with a volume of less than 20 m3, in which it is desired to prevent the formation of condensation inside them.

They are designed to operate in static air and have reduced specific power, so that the surface temperature of the heating elements is limited even in the presence of natural convection alone, making the presence of a control system superfluous (self-limiting heaters). The user will check the ambient temperature and turn off the heater when the desired temperature is reached. For heaters immersed in a potentially explosive atmosphere, the value of the maximum ambient temperature is indicated on the plate and must never be exceeded.

The electrical contact housing can be Ex-d explosion-proof or Ex-e increased safety.

The certifications available for safe areas are CE, IEC, EAC and with UL-Recognised certified heated elements; while for use in explosive areas ATEX, IECEx, EAC, UK CA and INMETRO.
