GENERAL SAFETY CONSIDERATIONS
WARNING: COMPRESSED AIR COULD CAUSE DEATH,
BLINDNESS OR INJURY
1. Do not operate a Vortex Cooler at compressed air
pressures above 150 psig (10.3 Bar).
2. Do not operate at line temperatures above 110
o
F
(43
o
C).
3. Avoid direct contact with compressed air.
4. Do not direct compressed air at any person.
5. When using compressed air, wear safety glasses
with side shields.

INTRODUCTION
A Vortex Cooler is designed to use filtered compressed air to
cool industrial cabinets without the use of any refrigerants.
An internal Vortex tube lowers the temperature and pressure
of the compressed air supplied to the enclosure. Hot air in the
cabinet is vented to the surroundings through a built in relief
valve in the Vortex Cooler.
Vortex Coolers can be used with or without electric
thermostats and solenoid valves.
COMPRESSED AIR SUPPLY
The compressed air supply must be filtered to remove water
and dirt using a 5 micron or smaller filter. Failure to use a
filter may cause clogging (and freezing) of the compressed
air paths inside the Vortec product. Filter recommendations
are given in Table 1.
Filter elements must be changed on a regular basis.
Frequency of change is determined by the condition of the
compressed air supply. Filters should be installed in the
compressed air supply line as close as possible to the Vortec
product.
The appropriate size of compressed air supply line should
be selected to ensure optimal performance of the Vortec
product. Please refer to Table 2 to determine what supply line
size is recommended for your application. Contact Vortec at
1-800-441-7475 for further assistance.
MAINTENANCE
Vortec Cooler systems have no moving parts and can be
disassembled for cleaning.
INSTALLATION AND OPERATION
To maintain the Type 4X rating, Type 4X Vortex Coolers
must be installed in a vertical orientation on a flat horizontal
surface at the top of the cabinet.
Vents in the cabinets must be covered and sealed to ensure
cooling efficiency and to keep out ambient air. When a
thermostat is supplied with a Vortex Cooler system for Type
4X enclosures, the thermostat can be easily readjusted using
the temperature indicator dial. All wiring must be installed in
an approved conduit.
Installation procedures:
1. Cut a 1-15/16” (49 mm) (1-1/2” knockout size) hole in the
enclosure.
2. Insert Vortex Cooler into cut-out and secure with the
locknut.
3. Attach the cold air muffler to the outlet of the Vortex
Cooler.
4. Perforate the ducting kit with several 1/8” holes and
secure to interior of enclosure.
5. Attach the ducting kit to the cold air muffler.
6. Connect compressed air filter and/or valve and
thermostat, to the Vortex Cooler (wire thermostat directly
to solenoid valve). Install the compressed air filter and
solenoid valve as close as possible to the Vortex Cooler,
in a location where the temperature does not exceed
125
o
F (52
o
C).
8. Connect compressed air supply to the filter.
TROUBLESHOOTING
Insufficient airflow may be caused by the following:
1. Undersized compressed air line size.
2. Compressed air pressure too low.
3. Partial or complete blockage of internal compressed air
path, due to dirt.
Insufficient cold air temperature may be caused by:
1. Compressed air line temperature too high.
2. Water vapor in the compressed air supply.
3. Loose cold cap. This may occur if not tightened properly
after disassembled for cleaning.
If trouble persists, please contact Vortec at 1-800-441-7475.
