120 °C
This heating design - which features a special electronic temperature
control unit - enables the utilisation of diesel motors which must be
started or operated under -20°C.
This type of heating prevents the condensation of gases and liquids
at temperatures under
-20°C. The heating is switched on through an outdoor sensor when
an optionally selectable lower temperature falls short of the setting.
A timer releases the heating power only after start-up of a dynamo
in order to prevent the battery from being emptied. A second
integrated control mechanism adjusts the operating temperature.
It turns off if the outdoor temperature exceeds -20°C. In addition,
the heating has excess temperature protection.
The outer protection material consists of PTFE-walled glass silk
fabric which can withstand very rough conditions of utilisation.
At customer request, this heating with invisible, built-in control unit
can be supplied as a collar with Velcro fastening or as a structural
fl at mat.
Heating sleeve 250 °C
for tubes and cartridges
The heating sleeve is a special physical form that can be adapted to
the specifi cations of tubes and cartridges. Conventional dimensions
as well as special shapes for one or more casks can be realised.
The fi nished heater consists of a heated inside tube, thermal insula-
tion and an outer jacket. These are available in a diverse array of
high-quality materials that can be selected to match the applica-
tion. The compact design with self-regulating PTC heating elements
or standard heaters with integrated regulation guarantee optimal
functionality and the highest level of safety.
