Attention: Dust-laden gases, deposits and condensed solvent vapor can
restrict air flow out the silencer. The resultant back pressure can lead to
damage of pump bearings, diaphragms, and valves. Under those condi-
tions, a silencer must not be used.

Determine the temperature of the available coolant.
+
In most cases the coolant temperature is given (e.g., tap water, in
house cooling water circuit). For maximum solvent recovery, carefully
choose the boiling point of the product (by choosing the vacuum level)
and the bath temperature accordingly.
+
Determine the lowest boiling point of the product (solvent).
+
The temperature difference between the product’s boiling point and
the coolant should be more than 68°F (20°C), otherwise a low vacuum
level will lead to significant loss of solvent.
+
Select a water bath temperature of 68-86°F (20-30°C) above the prod-
uct’s boiling point to provide sufficient heat transfer.
