transfer oil are used for circulating temperatures
above 200°C.
Dealing with thermal oil makes it necessary
to take different criteria into account
which also have a constructive
infl uence on the design of oil temperature
controllers.
Hot thermal oil has a low oxidation stability
when direct contact to ambient air is
allowed as found in some competitors
units which use a submersible pump and
tank. This increase of air absorption can
cause the oil to become more viscous
and the pump fl ow rate to decrease.
As an open design does not allow for a
defi ned fl ow with reliable monitoring this
oxidation due to the lowering fl ow rate
can cause an excess of oil fi lm at high
temperature on the heating element
which will lead to a tarry coating and carbon
deposits forming within the heat
transfer system eventually leading to the
decomposition of the oil and subsequent
