Suggested Optional Equipment Available
The purpose of this option is to provide Controlled humidity and
expand the testing capabilities for the CCT-NC. This option is often
used when tests such as the SAE J2334 require a controlled RH
condition in the test profile. With this option the chamber
can control percent RH from 30 - 95% (+/- 5%) as limited by a 22oC
dew point and current laboratory conditions. Additionally, the
equipment is equipped with a Solid State Humidity Sensor to report
back to the controller the exposure zones’ current humidity percentage.
NOT ALL TEMPERATURE AND HUMIDITY COMBINATIONS ARE ATTAINABLE!
(Check with factory for details)
This option provides the CCT-NC with the capability of
producing a spray onto the samples from a series of spray nozzles.
A solution pump connected to the 60-gallon reservoir moves solution to
a spray header inside the exposure zone of the chamber and delivers
solution to the spray nozzles. The spray header is located at the top
perimeter of the exposure zone and includes 8 to 12 nozzles depending on
the size of the chamber. Each nozzle can be independently directed to
a location requiring a spray. In addition, each nozzle has a shut off
valve giving the user the ability to turn off nozzles not required for
that spray application due to changing chamber loading.
This shut off feature will extend the life of the solution in the
60-gallon reservoir allowing an increased number or time of spray
applications between tank fills. This option is necessary when a
solution spray is required rather than a solution fog or atomization.
his option is commonly used in the 9540P specification.
This is a much simpler (S-Style) version of the above described
deluxe solution spray option. It works in basically the same
way as the deluxe version with two major exceptions. (1) There
are only two spray nozzles located in a fixed position over the
sample exposure zone. (2) These two nozzles do not have
independent shut off valves. This system also utilizes a smaller
pump system to feed these nozzles.
This system is ONLY available with the Computer Controls
There are three major ways of creating humidity in
environmental chambers. (1) Atomization of water, (2) Steam Generator,
and (3) Wet Bottom, or a heated bath of water. With this option,
the Wet Bottom humidity is created by flooding the bottom of the
CCT-NC chamber with water over the chamber heaters and then,
energizing the heaters. A 100% humidity condition is then created
in the exposure zone. This is an important method of humidity
generation for certain test specifications such as SAE J2334.
The best correlation to outside exposure for the SAE J2334 was
accomplished using this wet bottom humidity as compared to
fogging or steam generation. Note there is NO fogging occurring
during this condition.
This system is ONLY available with the Computer Controls
This option provides the CCT-NC with the ability to
automatically immerse the samples in the exposure zone.
This option includes the following:
- Immersion solution holding tank on a stand to match the style and color of the CCT-NC chamber. NC-40 or 90 chambers use a non-matching holding tank.
- Cover system for the Immersion solution holding tank
- Pumps to move the solution between the CCT-NC exposure zone and the immersion solution holding tank
- Motorized valve to direct the flow of the solution
- Agitation system for mixing the immersion solution
- Solution heating system for heating the immersion solution
- Level switches to monitor the solution levels and locations
As indicated above, this system can be used to mix and heat the immersion solution. All programming and controls needed to activate this system are included in the Computer (PC) controls package. With immersion, voltage selection must be 3
This system is ONLY available with the Premium Controls
The purpose of this option is to make the CCT-NC chamber
ready to accept a field installed immersion package.
This would be useful to customers who can not add the
immersion package to the chamber with the original chamber
order, but would like the ability to add the immersion package
in the field at a later date. This option includes:
- An electrical panel that is set-up to connect to an immersion panel in the field.
- All necessary programming will be loaded into the chambers controller.
- Chamber exposure zone and stand will be modified to hold the volume of immersion solution and the weight of the solution.
- Chamber exposure zone will be modified to accommodate the solution level switch with this puncture point being sealed until use.
With this option Auto Technology makes the necessary
wiring and component adjustments to exceed UL approval
requirements for this class of equipment. After the
chamber is built and tested, a UL inspector visits the
Auto Technology facility and inspects the chamber.
After the inspection is complete, and the chamber has
qualified, the UL inspector affixes the UL label to the
equipment, and the equipment is shipped.
With this option Auto Technology makes the necessary
wiring adjustments to exceed the CSA approval requirements
for this class of equipment. NO CSA inspection is done at
the Auto Technology facility. The equipment is shipped to
the customer and it is the CUSTOMER’S responsibility to have
the equipment inspected for CSA approval.

NOTE: The 480 volt 3 phase wiring package (711XXX)
cannot be used in conjunction with the CE Label (700320)
option but CAN be coupled with the other wiring codes.
With this option, the CCT-NC chamber will be equipped to
create a “TRUE” lab ambient condition. True ambient, by
the fact that the cover opens automatically and exposes
the test specimens to actual laboratory conditions.
Once time has elapsed, the cover automatically closes,
and the test profile continues. In addition, the operator
can open and close the cover at any desired time by use of
the manual section of the operator interface.
In some laboratories where the length of vent stack
from the CCT-NC is more than 10’ or where there is
back-pressure into the laboratory it may be necessary
to use a power vent kit. This kit includes a venturi
style air pump in the provided PVC piping driven by a 100-CFM fan.
With the help of the venturi, the fan draws fog from the
exposure zone and sends it up and out of the customer
installed vent piping.
NOTE: This system is not always
effective in laboratories that have changing pressures in the
location of the CCT-NC or where vent runs are of long lengths over 15’.
Auto Technology suggested that the user employ the services
of a professional if these conditions are not resolved with
the power vent installation kit.
It is imperative that the CCT-NC chamber has a constant
supply of clean dry air. In particular, if the air has
oil in it, it can cause much damage to the chamber components.
This damage often manifests itself in the form of clogged
atomizer nozzles, malfunctioning float switches, low collection rates,
and contaminated tubing just to name a few. It is the
customer’s responsibility to ensure that the air supply is
clean and dry. To help with this, Auto Technology offers an
Oil & Water Extractor Kit that must be field installed by the
customer on the customer’s incoming air supply that has proven
to clean many problem air systems. This is not a guarantee to
correct all systems. If oil and contaminants are still a problem
after the installation of this system, the customer will have to
take additional action.
This option automatically solenoid ON allowing compressed
air to activate the SO2 valve. SO2 then travels through
the valve, up and through the flow meter (user settable)
and into the chamber via the ported dispersion tower cone.
This option is required to meet certain standards such as ASTM G85 Annex 4.
This option is only available when the CCT-NC chamber has
computer controls and the controlled RH option. The solid
state humidity sensor included with the controlled RH option
will deteriorate over time during corrosion testing due to
the corrosive environments the chamber creates. This automatic
retraction system will substantially reduce this deterioration
by removing the probe from the exposure zone during salt fog
and high humidity cycles. When the probe is retracted, a drying
system keeps the probe dry. Without this option, RH readings
will become less reliable over time, and may need to be calibrated
on a monthly basis as well as be replaced every 6 months in
order to ensure accurate readings.
This system is ONLY available with the PC Controls
The purpose of this option is to provide automated
unattended filling of the 60-gallon solution tank with DI water.
With this option, the user can simply actuate a tank fill
button on the PC controls and walk away. A DI water
solenoid will open, and start filling the 60-gallon solution tank.
A float switch located at the top of the tank will sense when
the tank is full and turn of the water solenoid leaving the
reservoir full of water. The DI water solenoid will not reopen
until the user physically actuates the tank fill button on the PC again.
This option provides an automated agitation system
in the 60-gallon solution tank. This agitation system
is operated by the chamber controller in a manual mode
once initiated by the user. This agitation will
dissolve the salt in the water to make a saline solution.
After the built-in timer has elapsed in time, this agitation
system will turn off until it is initiated again by the user.
Two features are included with this one option.
Located in the chamber’s 60-gallon solution tank this
tube is plumbed by the customer to an open drain.
This will prevent the solution tank from overflowing with
DI water while being filled. If an overflow condition
begins to develop, the DI water flows down the tube and
to the drain. Additionally, this overflow tube has indicator
markings to indicate the solution level in the 60-gallon
tank in both liters and gallons.
The purpose of the Wet Bottom Drain Assembly is
to allow the bottom of the cabinet to fill with
de-ionized water to a level just above the rod heater.
This water is heated, creating a moist, even heat throughout
the exposure zone, which helps maintain uniform condensation
to allow accurate collection rates. Further, it allows
the water to drain prior to dry cycles.
This option provides the user of the CCT-NC with a
way to check condensate collected during salt fog and
humidity cycles without opening the chamber cover and
interrupting the test in progress. This system includes a
funnel holding bracket for each funnel with tubing running
to the outside front of the chamber. These lines are
located in the front of the chamber just behind the front
access panels. The lines terminate with ball valves, and
empty into collection devices placed behind the front access panel.
Fiberglass support angle. For suspending samples or
support larger samples. These support angles are the
proper length to span the distance at the middle of the
chamber exposure zone.
The purpose of these bars is to hold 3” x 6” or 4” x 12” test panels.
These bars are fabricated of 3" wide x 1-1/2" thick polypropylene.
Slots are standard .070 saw cuts on a 15-degree angle from vertical
on 1-1/2" centers. These support bars are the proper lengths to span
the distance at the middle of the chamber exposure zone.
Fiberglass supports Rods are used for suspending samples
or support larger samples. These support Rods are the
proper length to span the distance at the TOP of the chamber exposure zone.
For holding test panels. Fiberglass rack 8-1/2” wide, 23” long.
Holds 2 rows of panels with 20 slots in each row with slots on 1” centers.
Slots are on a 15-degree angle from vertical.
This rack will hold a total of 40 panels. These should be used in
conjunction with the above listed fiberglass support angles.
This heavy-duty sample support system is manufactured of durable,
corrosion-resistant, fiberglass composite. This material is lightweight,
nonconductive, nonmagnetic and rustproof. This pultruded composite
provides superior strength and has a higher load capacity than molded
materials. These support “shelves” provide sample support while allowing
for heat and fog transfer in the chamber.
The purpose of these support shelves is to provide the customer with a way to set
samples into the chamber as they would on a shop bench or storage shelf.
Each support “plate” can support 165 pounds (75 kilo) of weight. Each CCT
machine can accommodate 2 or 3 of these plates depending on the size of the machine.
These “shelves” are sized to fit the chamber at the mid-level.
Mid – Level support shelf
This is a digital pH meter complete with pH probe unit, 4 oz.
polyethylene bottles of 4 and 7 pH buffer solution,
adjusting screw driver and plastic carrying case. Used to
check the mixed solution and collected condensate in the chamber.
Consists of one 50-pound bag of salt, two (4) funnels and graduates,
one (1) specific gravity hydrometer and one (1) salimeter hydrometer.
Meets ASTM B117.
Consisting of filters, fittings, and tubing for necessary routine
maintenance to be performed in the first year of operation.
This is an extra tank that matches the one already provided with the
chamber. This option is useful when the customer desires longer
unattended testing between solutions fills or would like to mix and
adjust a batch of solution prior to transferring it into the chamber’s
main 60-gallon solution tank. This system includes an air agitation
system and a manually operated (air driven) solution transfer pump.
In addition, fittings are included to allow the user to operate this
tank in series with the original tank for the longer unattended testing.
This tank is mounted on a stand with caster and leveling bolts.
Each CCT-NC chamber is fully tested at the factory. Calibration of
the temperature sensing devices, pressure-sensing devices, humidity
sensing devices and the controller are all checked and adjusted by Auto
Technology if needed. This option provides the actual Certificate
of Calibration paperwork traceable to a N.I.S.T. standard created by
Auto Technology for a particular machine. This option must be ordered
with the original equipment purchase to receive the price quoted.
If it is purchased at a later date, the purchase cost will increase
and a quote will need to be prepared based on the timing of the purchase
and location of the equipment.
This is a hands on class designed to teach the participants how to
install, operate and maintain the CCT-NC. If participants are
interested, minor annual maintenance procedures can be performed
on the machine for practice and training. Almost the entire class
is conducted on the shop floor with a fully function chamber.
This class is conducted at the Auto Technology facility in Strongsville, Ohio.
Classes are scheduled on a mutually beneficial date for both Auto Technology
and customer personnel. Up to eight participants from a single company are
permitted to attend for one flat fee.
This is the same class as described above except that it takes place at
the customer’s facility. The training is conducted on a machine the
customer has installed and running. Another major difference with this
option is that the Auto Technology personnel will check the installation
of the chamber to ensure that it is correct. Classes are scheduled on a
mutually beneficial date for both Auto Technology and customer personnel.
Cost will vary depending on travel time and travel expenses.
