ESCRIPTION

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 to the mold or
process. The fluid returns to the
unit through the “From
Process” line for reheating
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
.

The temperature of
the process fluid is
measured as it flows
into the cooling tank
through the “From
Process” line .

If the temperature is above
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
Out” line .

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
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.
