The cause for this relatively high temperature is the self
heating of the bath due to friction-heat of the pump. The
insulation of the bath prevents this energy to be
transferred into the environment. This causes a raise of
temperature in the bath up to 25 .. 30°C depending on the
environmental temperature and used bath fluid.
For cooling the bath down to lower temperatures, tap-
water is mostly used. Also a small circulator can be
connected to the cooling coil like the Tamson TLC10-3,
or TLC15.

Over-temperature safety
In case of electronic failure the possibility exists that the
heater element is continuously switched on. This will
cause extreme temperature raise. To prevent high
temperatures the bath is fitted with a mechanical
temperature switch (thermostat). This thermostat will
switch-off the bath at a preset temperature in the range
from 50 tot 270°C.
We advise to adjust the mechanical over temperature to
approxi 25 C above the bath set point.
This safety construction prevents for example oil to be
heated above flash point which definetly will cause fire or
prevent evaporation of bath fluid due to high
temperatures.
The thermostat will automatically reset when the bath
temperature drops approximately 10°C below the pre-set
temperature. To continue normal operation the bath has
to be switched-off and on again.

Adjusting
The
Mechanical
Over-
Temperature Protection Thermostat
•
Turn the over-temperature protection (8, drawing
2) to its maximum (turn clockwise towards 50°C),
•
Heat the bath to its set point,
•
Gently turn the over-temperature protection anti-
clockwise, until the over-temperature protection is
activated, and system switches-off,
•
Turn
the
over-temperature
protection
approximately 25°C higher (turn clockwise),
Switch the bath off and on again. The bath is ready to
operate safely.
