Temperature
The control temperature can be set between –80°C and +80°C.
Because the rotational vacuum concentrator has no active cooling,
it is not possible to reach temperatures below room temperature.
Under certain conditions (e.g. if a frozen product is loaded) it may
be reasonable to choose a temperature below room temperature.
Vacuum (only if a vacuum sensor is installed)
Set value for the control vacuum in the rotor chamber. The value
range is defined from 1,000 mbar to 0.1 mbar.
Safety pressure (only if a vacuum sensor is installed)
The safety pressure includes also the preselection of the pressure at
which the heater is started for controlling the temperature of the
buckets. If the safety pressure is exceeded, the heater will be switched
off.
The set value of the safety pressure is defined at a value range from
1,000 mbar to 0.1 mbar. In the case of a set vacuum between 1 and
100 mbar, the set value of the safety pressure should be 5 mbar
higher. In the case of a set vacuum between 100 and 1,000 mbar, the
set value of the safety pressure should be 10 mbar above the set
vacuum.
Changing the set values:
Select the desired set value with the focus and the up/down
keys.
