5.7. Degasifying
During the filling process the pump fluidizes air bubbles into the
tempering liquid. In the automatic degasifying mode those and other light
solvent substances are slowly drained from the oil via the breather tube.
Notice:
In the automatic degasifying mode the breather tube between heating
and cooling zone is opened again and again. Hot gases and self-
extending tempering liquid therefore get into the cooling zone. Therefore
in case of a target temperature which is higher than 150°C a counter-
cooling in the cooling zone should be possible.
