TEMPERATURE CONTROL UNITS
Thermolator® vacuTrac (VTR1-DI and VTR2-D2)
Positive/Negative Temperature Controller
FEATURES
Expansion/fluid reservoir
accepts thermal expansion
of fluid when heated.
High efficiency pump
pushes fluid through
the system.
Air/water separation
tank allows entrapped
air to escape to the
expansion tank.
Pressure relief valve
prevents system
over pressurization.
Venting line prevents
trapped air in system.
Cooling check valve
prevents coolant back
flow into the vacuTrac.
Level switches
control tank fluid level.
Make-up solenoid valve
maintains tank level.
Cooling solenoid valve
lets hot fluid out of system.
Vacuum generating jet
pump/venturi
To process
pressure gauge
Three-way ball valve
diverts flow to
generate vaccuum.
From process

Positive/negative pressure
units use a jet pump/venturi to
produce negative pressure in
the “from process” lines.
Water at positive pressure
will leak out of mold cracks or
bad o-rings. During negative
pressure operation, however,
air is drawn through the lines,
and the mold operates without
leaking. A manual three-way
ball valve can be closed to
make these units into stan-
dard direct injection units.
Because the units use water
and vent to the atmosphere,
they have a maximum process
temperature of 180° F.
