The temperature of the process
fluid is measured as it leaves
the unit's heater tank. The fluid
then flows through the "To
Process" line
process. The fluid returns to the
unit through the "From
Process" line

or cooling.

If the process temperature
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.
Pressure is measured before
and after the pump

ESCRIPTION
:
Closed Circuit models maintain the process temperature by
electrically heating and indirectly cooling fluid in the
process circuit. Cooling water supplied by a chiller, tower
IRCUIT
or other water source, is mixed with the process fluid only
during the initial filling or when water is needed to make
up process fluid loss.

If the temperature is above
3a
the setpoint value, the cooling
valve opens. Cool water
enters the cooling piping
and circulates through a tube
heat exchanger to cool the
process fluid. The cooling
valve allows warm fluid to
escape through the "Cooling
