Vortex 727 Use and care manual
WARNING: COMPRESSED AIR COULD CAUSE DEATH, BLINDNESS
OR INJURY
1. Do not operate the Cold Air Gun at air pressures above 150 psig (10.3 Bar).
2. Do not operate the Cold Air Gun at line temperatures above 110°F (43°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.
Installation and Operation
Type 4 or 4X Vortex Coolers must be installed in a vertical orientation on a flat horizontal surface at the
top of the cabinet.
Type 12 Vortex Coolers should be installed in a vertical orientation on a flat horizontal surface at the top
of the cabinet, or in a horizontal orientation on a flat 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 4/4X/12 enclosures, the thermostat
can be easily readjusted using the temperature indicator dial. All wiring must be installed in an approved
conduit.
GENERAL SAFETY CONSIDERATIONS
Installation Procedures:
1. For Type 4 or 4X units: Cut 1-15/16” (49 mm) (1-1/2” knockout size) hole(s) in the enclosure.
For Type 12 units: Cut 1-1/8” (29 mm) (3/4" knockout size) hole(s) in the enclosure.
2. Insert Vortex Cooler(s) into cut-out(s) and secure with the locknut(s).
3. For Type 4 or 4X units: Attach the cold air muffler(s) to the outlet of the V ortex Cooler(s).
4. Perforate the ducting kit(s) with several 1/8” holes and secure to the interior of enclosure.
5. For dual cooler units: Attach the ducting kits to the cold outlets of the Vortex Coolers.
For all other models: Attach the ducting kit(s) to the cold air muffler(s).
6. If installing a solenoid valve and thermostat, connect pipe from Vortex Cooler to solenoid valve,
then pipe from solenoid valve to compressed air filter. The thermostat should be placed inside the
enclosure cabinet, and connected to the solenoid valve with conduit.
If not installing a solenoid valve and thermostat, connect piping from Vortex Cooler directly to
compressed air filter. The compressed air filter and solenoid valve should be installed as close as
possible to the Vortex Cooler, in a location where the temperature does not exceed 125 F (52 C).
Conduit and compressed air pipe are not provided.
7. Connect the compressed air supply to the filter.
Maintenance
Vortec Cooler systems have no moving parts and can be disassembled for cleaning.
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.
