Condenser

Still condensers are the horizontal type, slightly
inclined and atmospherically vented for final
elimination of volatiles. The condensers are fab-
ricated of copper and brass and are finished in
polished nickel. All surfaces that contact the
vapor and distillate are coated with pure tin to
prevent metallic contamination. A distillate
delivery tube of block tin is provided to connect
the distillate outlet of the condenser to a storage
tank or other suitable container.

Features Provided

All stills are equipped with a deconcentrator to
continuously deconcentrate impurities from the
evaporator and retard scale formation. A con-
stant level device with hot well arrangement is
provided for evaporator water level control and
for primary elimination of volatile impurities. All
stills are equipped with a drain valve. Cooling
water      discharge piping is provided between
the cooling water outlet of the condenser and
the constant level device. Self-resetting solid
state low water cutoff controls prevent the heat-
ing elements from burning out in a low water sit-
uation.

Electric Heat

Electrically powered, immersion type heaters are
used to give complete heat transfer and maxi-
mum heating efficiency.

Low Water Cut-Off 

Electric current to the still heating elements is
controlled by an ON/OFF switch and a self-
resetting low water cutoff. The solid state low
water cutoff is designed to prevent damage
caused by low water conditions in the still
evaporator.

Note

Heater life may be reduced
when operated above maximum
stated voltage. Operation of still
at a voltage less than the stated
voltages will cause a drop in still
output. Electrically heated stills
wired for 240 volts AC, 2 or 3
wire, will operate on 208 volts, 2
or 3 wire respectively with resul-
tant 25 percent drop in distillate
capacity. Special    heaters for
208 volts are needed to obtain
rated still output. The electric
heaters will burn out if operated
in air. To eliminate the possibility
of heating element burnout, a
solid state low water cutoff con-
trol is provided.
