8.3 Hose connections

8.3.1 Temperature control unit (with liquid):

 The temperature control unit with liquid temperature
control is connected with hoses to a heating bath and
circulator.
!
While fastening the hose connections at the con-
necting nozzles (14) of the temperature control unit
the connecting nozzles must be held up by
wrenches.

Direction of flow of the liquid
Temperature range up to 150 C:
Viton hoses
Hoes nozzle -Set
Temperature range of 100 C up to 350 C:
Metal hoses
Hoes nozzle -Set
Liquid temperature control:
Temperature range up to 100 C:
Thermal liquid in the temperature range between --50
C and 30 C: water with anti-freeze.
Temperature range from 5 C to 90 C: distilled water.
Distilled water
Normal mains water causes cable deposits and
frequently requires the unit to be descaled.
In principle, water up to 95 C can be used. However,
above 80 C, so much water evaporates that it requires
frequent topping--up.
Water with anti- -freeze
If you intend working at temperatures below 5 C,
anti--freeze must be added to the water. The added
amount of anti--freeze should be sufficient for a
temperature that is about 10C lower than the intended
working temperature. This prevents the freezing of
water on the evaporator coil of the cooling circuit, the
surface of which is always much colder than the
