FREE STANDING CTA

Introduction

The Freestanding CTA has been designed to apply a consistently mixed solution onto the wheels
of a vehicle, as the vehicle travels through the wash. The recommended placement for this
application is after the enter switch and before a high-pressure rinse, allowing enough room for
the chemical to react. Dwell times will vary based on the type of chemical being used, contact your
chemical supplier for dwell time guidelines.
The Primary applicator includes a 1/2” and 1/4” tee on the back of the manifold and should be
installed on the equipment room side of the bay. The secondary applicator should be positioned
across the bay in-line from the primary applicator. The tees on the primary applicator will deliver
the chemical/water mixture and air to the secondary applicator, using 1/4” and 1/2” poly-flow
tubing.

A Bell Hose style switch can be used in a tunnel or drive-through application to signal the input
and turn on the applicators, and is to be installed 6” from the center of the applicators to the center
of the bell hose. The length of time chemical is dispensed from the applicators is set within the
electrical enclosure on the pumping panel. An OFF delay timer inside the electrical enclosure will
need to be adjusted to match the line-speed, or traveling speed of the vehicle in a drive-thru
application.
CTA Applicators that are installed in a tunnel which has the tire tracking capability do not include a
bell-hose. The applicators will be controlled from a tunnel controller, based on the position of the
vehicle. The controller tire tracking feature will detect the position of the vehicle tires and enables
the tunnel controller to turn ON wheel-based applicators without installing a separate tire sensor
for each component.
A cross over tube will be used in a drive-thru application to run the utilities from the primary
applicator to the secondary applicator. The cross over tube should be positioned 3-1/4” inches
from the center of the applicators to the center of the tube, and will act similar to a speed bump
slowing or stopping the vehicle to allow the wheel of the vehicle to sit in the spray path to
maximize coverage.
The delivery panel has a 120-volt electric solenoid valve that will flow air to two regulators. One
regulator feeds the air pump that will deliver the premixed solution out to the applicators, and the
other regulator will deliver compressed air to help make the chemicals foam. A 1/2” poly-flow tube
will run from the outlet of the pump, and a 1/4” poly-flow line from the foam air regulator on the
delivery-pumping panel to the primary applicator. This system includes a reservoir, that when the
solution drops below the preset level the Hydro-minder float opens a non-electric magnetic valve.
The flow of water siphons liquid concentrate into the water stream, automatically maintaining the
level of ready to use solution. The dilution ratio is adjusted with the metering tip selection (orifice)
that is screwed into the siphon stub on the inductor body.
