Tests for Condenser Leaks
Visual Test
. A simple test for condenser leaks
may be performed as follows:
1.
Shut off the still heating elements.
2.
Let the cooling water flow through the
condenser until the condenser is cold.
3.
Note whether there is a flow, even in
drop quantities, from the distillate outlet.
If there is a continuous flow, it is possi-
ble that there is a leak from the cooling
water side to the distillate side. If this is
the case, the condenser must be re-
placed.
Pressure Test.
If a more positive test is re-
quired, proceed as follows:
1.
Remove the condenser from the still.
2.
Remove the cooling water discharge
tubing. Plug the discharge connection
on the condenser with a plug or stop-
per.
3.
Attach a hose to the cooling water inlet
connection on the condenser and apply
about 5 psi air pressure to condenser.
Ensure that the plugs used to seal the
condenser do not leak air.
4.
Submerge the entire condenser in a
tank of water.
