SECTION 7 –
SPRAY SYSTEMS
The direct Modular Injection System can
be ordered and installed during production or
aftermarket on STS machines. The system is
offered in the following configurations:
• One Chemical Tank/One Injection Pump
• Two Chemical Tanks/Two Injection Pumps
NOTE: Chemical Tank Capacity = 55 gallons
(208 L)/each.
This system allows the operator to quickly
change from one chemical to another without
rinsing the main tank in between. Chemical
application rate can also be adjusted by
concentration variation, which improves
application efficiency.
The Modular Injection System accurately
injects concentrated chemical, where it is
then mixed with water (stored in the main
tank) just prior to being applied. Therefore,
there is no need to pre-mix chemicals
beforehand. There is also no need to dispose
of any remaining chemical mixture at the end
of use, as unused chemical may remain
stored in the chemical tank(s).
The concentrated chemical is extracted
from the chemical tank, where it is then sent
to the in-line suction strainer, and then routed
to the injection pump. From there it is sent to
the flow indicator (mounted on the outside of
cab), and then to the mixer assembly (where
the chemical is mixed with water). From the
mixer assembly, the solution is then applied
through the spray booms.
The following information refers to
components of the Modular Injection System
and is not intended to replace the
manufacturer’s operating instructions.
