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 valves.
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
To maintain the Type 4 or 4X rating, Type 4 or 4X Vortex Coolers
must be installed in a vertical orientation on a at 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 4 or 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 two 1-15/16” (49 mm) (3/4” (1-1/2”) knockout size) holes in
the enclosure.
2. Insert the Vortex Coolers into the cut-outs and secure with the
locknuts.
3. Attach the Cold Air Mufflers to the outlets of the Vortex Coolers.
4. Perforate the ducting kits with several 1/8” (3 mm) holes and
secure to interior of enclosure.
5. Attach the ducting kits to the Cold Air Mufflers.
6. Connect compressed air lter and/or valve and thermostat, to
the Vortex Coolers (wire thermostat directly to solenoid valve).
Pipe ttings are provided for connecting the compressed air
lter, solenoid valve (in 7975 and 7975SS models) and Vortex
Coolers. Additional piping must be provided by the end user.
7. 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.
