Adjustment Of Water Flow At Disc Cooling - Struers RotoPol-31 Mode D'emploi

Adjustment of Water Flow at
Disc Cooling
RotoPol-31/-35
Instruction Manual
ALWAYS OFF should be selected if disc cooling is not
relevant for the application.
Disc cooling will automatically start and stop with
RotoPol-31/-35.
- Disc cooling will only be active at rotational speeds up to 300 RPM.
- Disc cooling is only efficient when aluminium discs are being used.
Select mode WHEN WATER OFF or ALWAYS ON in the disc
cooling menu.
Select WATER OFF
31/-35 without a preparation disc.
Adjust the flow using the valve at the rear of the cabinet so
that the cooling water flows from the hole in the centre of the
turntable at a height of about 2 mm. This will result in a
water flow of about 250 ml/min which will generally be
adequate.
RotoPol (RotoPol-31)
Valve for Disc Cooling
Disc cooling works with both tap water or by means of
recirculation. The cooling capability for Recirculation Cooling
Unit (TRECI) will be sufficient for most situations. If, however,
the equipment is used very intensively, using recirculation, the
temperature of the cooling water may vary too much during
working time to be adequate for disc cooling. In this situation, a
separate cooling system (available from most laboratory
suppliers) should be connected to the Recirculation Cooling Unit.
