6-1: Water and Chemical Systems
6 - Water and Chemical
System
This section describes the Boxxer XL’s water and chemical systems, and includes the
exhaust subsystem (see figure 6-1 - figure 6-3).
1. The process starts when fresh water is brought through the front of the truckmount
into the water box. The level of water in the box is maintained by the use of a float
valve. The water is then gravity-fed to the pump where it is pressurized.
2. Next, the pressurized water enters the by-pass valve. This valve allows manual
adjustment of the pressure level. When the valve at the wand is closed, all the water
in the system is recirculated to the water box. When solution is being used at the
wand, the necessary amount of high pressure water passes through the by-pass
valve and to the heat exchanger.
3. In the tube and fin heat exchanger, the temperature is raised. The heat necessary
to do this is provided by the engine. Heated water then travels to the blower heat
exchanger. In this heat exchanger, the temperature of the water is raised once again.
The heat necessary to do this is provided by both the engine and blower exhausts.
The heated water finally travels to the high pressure manifold.
The high pressure manifold houses both the temperature sensor for the
temperature gauge and the high temperature shutdown switch. This innovative,
revolutionary system does not require a recirculation orifice or filter to maintain
temperature within the heating system.
When water is not flowing through the cleaning tool, the water within the heat exchange
system stops circulating completely.
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.
