Thanks to the incorporation of selfregulating
positive temperature
coefficient (PTC) technology, Rittal
enclosure heaters provide a high level
of energy efficiency. Developed using
computational fluid dynamics (CFD),
the heaters provide efficient heating
performance while maintaining the
physical dimensions of previous
models. Fitting is by either snapfastening
onto 35mm support rails or
direct screw-fixing onto the
mounting plate and the quick and
easy assembly is completed using
clamp-type wiring terminals.

Precise temperature control is
achieved simply by including a
thermostat in the supply to the
heater. Alternatively, where low air
temper atures inside the enclosure are
to be avoided to prevent the
formation of condensation, control
may be effected by connecting a
hygrostat in the same manner.
