Steamatic 8800 TMU
Water temperature is controlled via a temperature sensor inside the heat exchanger.
When the system achieves the maximum operating temperature, the diverter valve will
“divert” all heat away from the heat exchanger which allows the system to control its
internal temperature without dumping water.
This saves valuable space in the recovery tank, which can be used instead for recovery
of dirty water from the cleaning surface.
Water that is recirculated through the pressure regulator back to the water box
4.
travels past a thermovalve. This thermovalve monitors the water box temperature.
When the controller senses the water in the water box has reached its set point, it
opens the low pressure thermovalve on the side of the water box and closes once
the temperature drops back below the set point (see figure 6-2).
The water that is being called for by the wand then exits the manifold and passes
5.
through a check valve (see figure 6-2).
finally, the water joins the chemical where the solution is created (see
6.
figure 6-2)
The chemical is pressurized by the diaphragm chemical pump attached to the head
7.
of the water pump. This pump pulls the chemical from the chemical, or soap, jug
through the chemical flow meter (see
figure 6-3).
After being pressurized, the chemical travels through the metering valve and
8.
is injected into the high pressure stream. This solution then exits the front of the
truckmount and is delivered to the cleaning tool (see figure 6-3).
