How It Works: Isolated Circuit - Conair Thermolator TW-1 User Manual

Isolated Circuit models maintain the process temperature
by electrically heating and indirectly cooling fluid in the
process circuit. The process fluid, which is stored in a
reservoir, is isolated from cooling water supplied by a
chiller, tower or other source.
The temperature of the
1
process fluid is measured
as it leaves the unit's
heater tank. The fluid then
flows through the "To
Process" line to the mold
A
or process. The fluid
returns to the unit through
the "From Process" line
B
for reheating or cooling.
If the process temperature
3b
is below the setpoint, the
heater elements inside the
heater tank are energized.
The pump moves water

from the mixing tank to
the heater tank.
