Robust barrel heating mat
Heating sleeves to heat segments of 200 litre barrels per DIN. Both
the inner and the outer sheath of the barrel heating sleeve are
made of aluminium sheet, which ensures maximum protection of
the electrical components against mechanical damage.
A hinge with clamping closure that divides the heating surface into
two semi-shells permits convenient assembly, without the heating
element needing to be bent. The barrel can be heated complete
by using 3 sleeves.
The integrated thermal insulation increases effi ciency and reduces
the temperature of the touchable surfaces. In the attached alu-
minium housing, the heating surface temperature can be set in
a range from 30 to 110°C via a mechanical thermostat. In addi-
tion to the temperature controller, a 120°C thermal switch and a
140°C thermal fuse is built into each semi-shell to protect against
overheating.
With the HFT socket distributor it is also possible to precisely regulate
the temperature of the barrel contents via a temperature controller
and an immersed PT 100 sensor.
For lower temperature we recommend our heater tarp HP 60 on
page 64.
