Introduction
Zero Energy State (ZES)
CAUTION: Before performing maintenance or repairs on this product, you should
disconnect and lockout electrical power sources to prevent injury from unexpect-
ed energizing or start-up.
During maintenance, it is essential that the system be put into a state which
eliminates the possibility of components making an unexpected and dangerous
movement. This procedure is typically referred to as lockout. After all energy
sources have been neutralized, the system is in the zero mechanical state (ZMS).
This provides maximum protection against unexpected mechanical movement.
The lockout procedure must include all energy sources:
•Electrical power supply
•Compressed air supply
•Potential energy from suspended parts
•Pressurized process uid loop
•Cooling uid supply
•Cooling uid return
•Stored thermal energy
•Any other source that might cause unexpected mechanical movement or
energy release
The following is a recommended Zero Energy State procedure which must be followed
prior to any inspection, or maintenance of the TCU.
1 Turn o the all devices attached to the RQT Advanced.
2 Perform the proper shutdown sequence to the connected equipment and allow all
components (internally and externally) to adequately cool.
3 Disconnect and lock out the primary electrical supply feeding all attached
components.
WARNING: Before removing lockout devices and returning switches to the ON
position, make sure that all personnel are clear of the machine, tools have been
removed and all safety guards reinstalled.
4 Disconnect and lock out the compressed air supply (if equipped).
5 Isolate the RQT Advanced from other uids in the system, such as the main process
loop and the cooling uid supply and return.
6 Bleed o uid pressure that may be present in the various uid containing portions
of the RQT Advanced, keeping in mind that pressure can be the result of increased
temperatures

1-6 I Introduction
How to Use the Lockout Device
(if Equipped)
CAUTION: Before performing maintenance or repairs on this product, you should
disconnect and lockout electrical power sources to prevent injury from unex-
pected energization or start-up. A lockable device may be provided to isolate this
product from potentially hazardous electricity.
WARNING: Before removing lockout devices and returning switches to the ON
position, make sure that all personnel are clear of the machine, tools have been
removed and all safety guards reinstalled.
Lockout is the preferred method of isolating machines or equipment from energy sources.
Your Thermal Care product may be equipped with the lockout device pictured below. To
use the lockout device:
1 Stop or turn o the equipment.
2 Isolate the equipment from the electric power.
3 Turn the rotary disconnect switch to the OFF, or
“O” position.
4 Secure the device with an assigned lock or tag.
5 The equipment is now locked out.
If the machine has no included lockout device, perform the same procedure at the up-
stream device as part of premises electrical system. Incoming cooling water and com-
pressed air (if purge) are additional energy sources that need to be controlled.
NOTE: The incoming power wires on the top of the disconnect switch are still energized, even when
the machine is locked out. It is strongly recommended that electrical energy also be locked out at
the next upstream device if work is going to be performed in the electrical panel.

2-2 I Description
What is the RQT Advanced
The RQT Advanced circulates water at a temperature higher than the available water sup-
ply. It will add or remove heat as needed to maintain a uniform temperature setpoint in the
process.
The RQT Advanced is available in single or multiple-zone congurations for process
heating and cooling. Two-zone models can control up to two temperatures at dierent
locations in the process. Two-zone models have common cooling water manifolds and
electrical connections.
Typical Applications
The best model for your application depends on the process temperature you need to
maintain and the quality of the cooling water supply.
RQT Advanced direct injection (DI) models control the temperature by discharging heated
process water or adding cooling water directly from the water supply. DI models are
designed for:
•Process temperatures up to 250°F {121°C} - with options up to 300°F {149°C}.
•Use with chiller water or properly treated and ltered tower or city water.
Check to make sure all piping connections are secure and that all lines are suitable for
water or the coolant in the system at the maximum setpoint temperature and cumulative
pressure rating of the maximum pump pressure rise plus the cooling water pressure.
Make sure that the cooling source is the appropriate
temperature and pressure for your application. In most
cases, the cooling source is between 40°F {4°C} and 85°F
{29°C}. The minimum cooling source uid pressure must
be at least 30 PSI* in order for the unit to start. The maxi-
mum pressure is shown in this chart in order to meet the
pressure limitations of standard 150 psi, high-temperature
industrial hose/plumbing on the discharge side of the
pump.
*Adaptive Maximum Setpoint allows for operation below 30 PSI. This feature will
automatically adjust maximum temperature setpoint based o of supplied pressure with
certain heater and pump combinations.

Description
Typical Applications (Continued)
The limiting factor regarding the maximum cooling pressure is the presumed 150 PSI Rat-
ing of industry-standard hose. The hose must be able to withstand the maximum possible
process temperature at maximum possible pressure.
Your cooling water pressure may exceed the values shown in the chart ONLY if you are
utilizing specialty high-pressure/ high-temperature hose.
All RQT Advanced units have pressure transducers, and the software will limit setpoint
depending on average cooling source pressure. The pressure relief valve is located on
the “From Process” side of the pump, and will start to discharge if the pressure exceeds
135 psi. If this becomes an issue, install a pressure-regulating valve (available from our
Parts Department) on the cooling water supply line to help regulate the pressure to ensure
it is well below the pressure rating of the pressure relief valve. For further assistance in
installing a pressure-regulating valve, please contact our Customer Service Department.
System Fill Water Chemistry Requirements
The properties of water make it ideal for heat transfer applications. It is safe, non-am-
mable, non-poisonous, easy to handle, widely available, and inexpensive in most industri-
alized areas.
When using water as a heat transfer uid it is important to keep it within certain chem-
istry limits to avoid unwanted side eects. Water is a “universal solvent” because it can
dissolve many solid substances and absorb gases. As a result, water can cause the corro-
sion of metals used in a cooling system. Additionally, dissolved minerals naturally present
in tap water will precipitate out onto the system plumbing at elevated uid temperatures,
forming scale. The life giving properties of water can also encourage biological growth
that can foul heat transfer surfaces. See “Fill Water Chemistry” in the Installation section
of this User Guide.

2-4 I Description
How the RQT Advanced
Direct Injection Works
Direct Injection models maintain the process temperature by electrically heating and/
or injecting cool water supplied to the RQT Advanced by a chiller, tower, or other water
source.
Refer to the Direct Injection Plumbing Diagram for the RQT Advanced in Appendix C of
this User Guide.
1 The temperature of the process uid is
measured as it leaves the unit’s primary
heater tank. The uid then ows through
the “To Process” line A to the mold or
process. The uid returns to the unit
through the “From Process” line B for
reheating or cooling.
2 The temperature of the process uid is
measured as it ows into the mixing tank
through the “From Process” line B.
3 If the “To Process” temperature is above
the setpoint value, the cooling valve opens.
Cool water enters the bottom of the mixing
tank via the “Cooling In” line C. Warm
water ows out of the mixing tank via the
“Cooling Out” line D.
NOTE: The “From Process” or “Remote” can also
be configured as a controlling source.
4 If the “To Process” temperature is below
the setpoint, the heater elements inside the
heater tank are energized.
NOTE: The “From Process” or “Remote” can also
be configured as a controlling source.
5 The pump moves water from the mixing
tank into the heater tank. Pressure can now
be read through pressure transducers.
NOTE: This illustration is for representation
purposes only. Depending on your machine
configuration, your RQT Advanced may have an
additional heater or other options/configurations
not shown here.

Description
How the Closed Circuit Common Source
Works
Closed Circuit RQT Advanced models maintain the process temperature by electrically
heating and indirectly cooling uid in the process circuit. Cooling water supplied by a
chiller, tower or other water source, is mixed with the process uid only during the initial
lling or when water is needed to make up process uid loss. A brazed-plate heat exchang-
er replaces the mixing tank used on direct injection units.
Refer to the Closed Circuit Common Source Plumbing Diagram for the RQT Advanced in
Appendix C of this User Guide.
NOTE: The modulating
valve will be located
on the Cooling OUT
line, exiting the RQT
Advanced.
1 The temperature of the process uid is measured as it
leaves the unit’s heater tank. The uid then ows through
the “To Process” line to the mold or process. The uid
returns to the unit through the “From Process” line for
reheating or cooling.
2 If the temperature is above the setpoint value, the cool-
ing valve opens. Cool water enters the heat exchanger
via the “Cooling In” line. Process uid is always being
circulated through the process side of the heat exchanger.
The process uid is indirectly cooled via conduction from
the colder water now running through the cooling side of
the heat exchanger. If the measured temperature is below
the setpoint, the heater elements inside the heater tank are
energized.
NOTE: The “From Process” or “Remote” can also be configured as a
controlling source.
3 The pump moves water from the heat exchanger to the
heater tank. Pressure is measured before and after the pump
with pressure transducers. If the “To Process” temperature
is below the setpoint, the heater elements inside the heating
tank are energized.
