General Safety
Precautions

Electrostatic Discharge
Safety Precautions

Safety

Electrostatic discharge can be hazardous to the operator and the
equipment. The static charge of CO2 varies with the amount of ice and
humidity present. Follow these instructions to assure safe operation while
blasting.

A) The power outlet must have a good ground

This is critical for electrostatic dissipation. If the ground is not
connected a charge will build up on the unit or the applicator. As a
secondary backup the unit's electrically conductive wheels will help
bleed off any additional static charge.

B) The blasting unit’s static ground cable must be attached to the

target surface

If a target is on a non-grounded surface it will build up an electrostatic
charge, which could injure the operator or damage the equipment.
Wrap or clip the static ground cable to the target to dissipate the
charge. Metal framing, that holds the target in place, can be used but
the target and frame must be electrically connected. Use a conductivity
tester for confirmation.

C) Know your environment

Electrostatic buildup changes as humidity levels change and will vary
by location. Electrostatic discharge is higher at low humidity levels and
occurs most often during cold weather.

8

Carbon Dioxide (CO2) is a naturally occurring gas and a normal by-product
of breathing.

However caution MUST be exercised!

• This unit utilizes Carbon Dioxide (Dry Ice) as a blast media.

• Dry Ice is very cold -110°F (-79°C) and may freeze skin instantly.

• CO2 is a heavy gas, which means it will settle to the ground.

• Always ventilate when blasting.

• When blasting in a confined space, use of a Carbon Dioxide monitoring

device is recommended.

• CO2 is nontoxic, non-corrosive, non-conductive and is approved by

the FDA and USDA. While exposure to CO2 gas is not harmful in low
concentrations, CAUTION must be exercised when using any material
that can DISPLACE OXYGEN.

WARNING

This product utilizes Carbon Dioxide (CO2) as a

blast media, EXTREMELY COLD,

CAUSES SEVERE BURNS. CO2 can freeze

the skin instantly. Always use protective

clothing (Thermal Gloves) and eye

protection when handling CO2 solids or

when using the blasting unit.

Carbon Dioxide
Safety Precautions

Safety

WARNING

INCREASED LEVELS OF CO2 WHEN

BLASTING IN A CONFINED SPACE CAN

DISPLACE BREATHABLE OXYGEN

CREATING A RISK OF SERIOUS INJURY

OR DEATH BY SUFFOCATION, THEREFORE

USE OF A CARBON DIOXIDE MONITORING

DEVICE IS RECOMMENDED WHEN USING

IN A CONFINED SPACE.

IMPORTANT

ALWAYS MAKE SURE THE HOPPER IS

EMPTY AND BLAST WITH AIR ONLY,

FOR 1 MIN. WHEN SHUTTING DOWN

LONGER THAN 15 MIN.

FAILURE TO DO SO MAY RESULT IN

FEEDER AND/OR NOZZLE FREEZE-UP.

• For optimal performance it is recommended that the air supply dew

point be -40oF (-40oC) or lower.

• For optimal performance make sure the air is clean and free from oil

and grit.

• If needed, use an after-cooler and an air dryer with air filtration,

to obtain desired air quality and dew point (air drying and filtration
equipment may be purchased from Cold Jet).

• If you intend to provide your own air drying and filtration equipment,

consult Cold Jet Customer Support for assistance in selecting the
correct models.

• The length of blast time at higher dew points depends on relative

humidity, temperature and excessive condensation in the hopper and
on the pellets.

• At EVERY blasting start-up ALWAYS purge the Cold Jet AeRO 75 &

75-DX with compressed air before adding pellets to the hopper.

• ALWAYS shut the fill lid to avoid foreign objects falling in.

• ALWAYS avoid bad ice.

Component Guide

• The Cold Jet AeRO 75 & 75-DX are portable units providing easy

access for difficult to reach cleaning applications.

• The Cold Jet AeRO 75 & 75-DX use dry ice pellets from either an on-

site pelletizer or shipped in from a distribution center.

• The blast machine requires a source of compressed air and standard

electrical power for operation.

• The blast machine contains an innovative, patented feeder and control

system to maintain consistent pellet flow.

• During operation the feeder transfers the pellets from the hopper to

a stream of compressed air at a rate determined by the feed control
system.

• After exiting the nozzle and striking the surface, the CO

2

pellets

sublimate into the atmosphere.

• The only residue left behind is the blasted contaminant.

• The Cold Jet AeRO 75 & 75-DX have the capacity to hold 75 lbs (34

kg) of CO2 pellets.

• The delivery is variable from 0 - 7 lbs/min (0 - 3.2 kg/min).

• The Cold Jet AeRO 75 can blast from 30 - 140 psi (2 - 9.66 bar) and

the AeRO 75-DX can blast from 30 - 300 psi (2 - 20 bar). Below 60
psi (4 bar) a regulator is required.

Handling Pellets

Blasting Techniques

• POSITION the blast hose for maximum

maneuverability BEFORE blasting.

• DO NOT kink the blast hose.

• HOLD nozzles PERPENDICULAR

to the surface for fastest cleaning
(recommended for most applications).

• OPTIMUM STAND OFF DISTANCE is

2 in (5 cm) for most nozzles.

• NEVER ALLOW foreign objects to

enter the hopper!

• DO NOT abuse the blast applicator or

cable.

• BLAST with AIR ONLY for 1 minute

after breaks (to melt any water ice
build-up inside the blasting unit).

• SLIDE hopper access door open to

empty pellets.

• HOPPER SHOULD BE EMPTY

BEFORE REFILLING.

Tips

• KEEP pellet boxes and fill lid CLOSED at all

times.

• DO NOT use powdery or clumped pellets.

• USE a plastic scoop (not metal) to fill hopper.

• PELLET-BOX liner fragments should not

enter hopper.

• DO NOT BREAK THE SEAL on pellet box

until pellets are needed.

• USE pellets as soon as possible after

opening the box.

• STORE pellet boxes out of direct sunlight.

• DO NOT use pellets larger than 1/8-inch

(3mm) in diameter.

46

Appendix

The Cold Jet AeRO 75 series blast machine works best when the supply
air is free of any debris and has a dew point of -40°F (-40°C).

If Using Plant Air (Central Compressed Air System)

Manufacturing plants, with central compressed air systems, should have an
After Cooler and a 2-stage coalescing filter assembly downstream of the
receiver tank. Hot metal pipes are an indication this is needed.

To verify that the plant air system is adequate for the AeRO 75 (75-DX) the
air compressor needs to produce an air volume 10% greater than the blast
machine's maximum air volume...in addition to the air volume consumed by
normal plant operation.

To determine adequate air volume, blast while watching the pressure
gauge.

• If the gauge drops slowly the compressor is insufficient.

• If the gauge drops quickly there is a restriction or the pipe is too small.

• If the gauge stays steady then the compressor and piping are

adequate.

To maintain adequate pressure to the AeRO 75 (75-DX):

• From the air compressor to 50 ft (15 m) use a flexible 1 in (25 mm) air

hose (preferably the hose supplied with the machine).

• From the air compressor to beyond 50 ft (15 m) make sure the pipe is

1 in (25 mm) in diameter before attaching the air hose.

If an air drop isn’t used much, water and rust will collect in the line. Before
plugging into the air supply, purge the line, to prevent contamination of the
AeRO 75 (75-DX).

Blast Air Quality

Up to 140 psi (9.6 bar)

47

Appendix

If Using Portable Air (minimum of 185 cfm - 5.6 m

3

/min)

Portable diesel air compressors are mainly used for shop tools, not dry ice
blasting units and are therefore not able to cool or remove air moisture.
An after cooler with a 15°F (-9°C) approach is required to reduce the
discharge air temperature 180°F (82°C) to within 15°F (-9°C) of ambient air
temperature.

Without the after cooler, the following will occur:
1 Incoming air moisture will rapidly cool and freeze at the AeRO 75 (75-

DX) feeder.

2 Water ice will accumulate in the feeder, distorting the air flow and seal.
3 Water ice buildup will continue inside the blast hose, to the nozzle.
4 Water ice will break off inside the hose and lodge in the nozzle,

causing a jam.

5 Water ice, may exit the nozzle, and damage the target surface.
For the above reasons, an after cooler and moisture trap/filter must be
used.

If blasting continuously, use an air dryer to further reduce the air moisture
(dew point). Desiccant dryers produce a dew point of -40°F (-40°C),
resulting in a dew point low enough for continuous blasting.

To verify the compressor is of adequate size for the AeRO 75 (75-DX) the
air compressor needs to produce an air volume 10% greater than the blast
machine's maximum permissable air volume.

To determine adequate air volume, blast while watching the pressure
gauge.

• If the gauge drops slowly the compressor is insufficient.

• If the gauge drops quickly there is a restriction or the pipe is too small.

• If the gauge stays steady then the compressor is adequate.

To maintain adequate pressure, the hose size from the compressor to the
AeRO 75 (75-DX) needs to be 1 in (25 mm) in diameter.

will be made by CJ or its authorized representative free of charge to the Buyer,
except for any freight or travel expenses, during the warranty period. Any
replaced part will become the property of CJ. If, after repeated efforts, CJ is
unable to restore its Equipment to good working order, or to replace the defective
parts as warranted, CJ may, at its discretion, replace the Equipment in its entirety.
Any claim must be made to CJ, in writing, within 30 days of discovering the defect
and any claim not made within that period shall be deemed waived or released,
and thus denied.

Warranty service provided under this Agreement does not assume uninterrupted
operation of the Equipment. The suitability of the equipment for the purpose
intended is not included in the warranty.

This warranty shall not apply and CJ shall be neither responsible nor liable for:
a) Consequential, collateral or special losses or damages;
b) Equipment conditions caused by abnormal conditions of use, accident, neglect

or misuse of equipment, improper storage or damages resulting during shipment
as determined by CJ;

c) The replacement of normal wear items, including but not limited to air, blast and

whip end hoses;

d) Deviation from the Equipment’s prescribed maintenance programs, replacement

parts, operating instructions, specifications or other terms of sale;

e) Labor charges, loss or damage resulting from improper operation, maintenance

or repairs made by person(s) other than CJ or CJ-authorized service
representatives;

f) Improper application of the product. In no event shall CJ be liable for claims in

excess of the purchase price, whether there is a breach of contract or warranty
claim of negligence or negligent manufacture.

THIS WARRANTY IS THE SOLE WARRANTY OF CJ AND ANY OTHER
WARRANTIES, EXPRESS, IMPLIED IN LAW OR IMPLIED BY FACT, INCLUDING
ANY WARRANTIES OF MERCHANTABILITY AND FITNESS FOR PARTICULAR
USE, ARE HEREBY SPECIFICALLY EXCLUDED.
