Models 721, 730, 740, 780, 785, 790, 795 Models 711, 750, 760
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 110oF
(43oC).
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.
GENERAL SAFETY CONSIDERATIONS
WARNING: COMPRESSED AIR COULD CAUSE
DEATH, BLINDNESS OR INJURY
INTRODUCTION
A Vortex Cooler is designed to use ltered 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 valve.
COMPRESSED AIR SUPPLY
The compressed air supply must be ltered to remove water
and dirt using a 5 micron or smaller lter. Failure to use a
lter 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
For best results, Type 12 Vortex Coolers should be installed
in a vertical orientation on a at horizontal surface at the top
of the cabinet, or in a horizontal orientation on a at vertical
surface on the side 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
12 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 1-1/8” (3/4” knockout size) hole in the enclosure.
2. Insert Vortex Cooler into cut-out and secure with the
locknut.
3. Perforate the ducting kit with several 1/8” holes and secure
to interior of enclosure.
4. Attach the ducting kit to cold outlet.
5. Connect compressed air lter and/or valve and thermostat,
to the Vortex Cooler (wire thermostat directly to solenoid
valve). Install the compressed air lter and solenoid valve
as close as possible to the Vortex Cooler, in a location
where the temperature does not exceed 125oF (52oC).
6. Connect compressed air supply to the lter.
TROUBLESHOOTING
Insufficient airow 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.
