Specifications

Direct injection models maintain the process temperature
by electrically heating and injecting cool water supplied to
the Thermolator by a chiller, tower or other water source.

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 set-
point, 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 .
NOTE: Some higher kW models have an
additiona heater in the mixing tank

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

If the average temperature is
above the setpoint value, the cool-
ing valve opens. Cool water enters
the bottom of the mixing tank via
the “Cooling In” line . Warm
water flows out of the top of the
tank via the “Cooling Out” line .
