How vortex coolers
create cold air
Compressed air is injected into the
vortex tube at extremely high speeds
and that creates a cyclone, or vortex,
spinning a million revolutions per
minute. Part of the air is forced to spin
inward to the center and travels up
a long tube where a valve turns the
spinning column of air inside itself.
The inside column of air gives up its
heat to the outside column. The cold
air is directed out the cold end of the
Vortex Tube and the hot air is directed
out the other end of the Vortex Tube.
And since there are no moving parts
there is little need for maintenance.
•Uses clean, dry, oil-free compressed air
(80 to 100 PSIG / 70 degrees F or below)
required to achieve published BTU/H
ratings. Lower pressures and/or higher
temperatures will reduce BTU/H rating
•A 5 micron water and particulate
removal filter must be installed prior to
any vortex cooler operation.
•An oil removal filter can be installed
between the 5 micron filter and the
Vortex Cooler if oil is present in the
compressed air line.
•Thermostats, filters and valves that
work with Stratus Vortex Coolers are
sold separately and listed later in this
section.
•Operation above 100 PSIG is not
recommended. The use of a pressure
regulator will be necessary for higher
pressures.

You need to cool down
Get the heat out
Heat inside an enclosure can decrease the life expectancy of
controlling
units such as your PLC, HMI, AC drives and other
COLD
items. Excessive heat can cause nuisance faults from your
electrical and electronic components: for example, overloads
tripping unexpectedly. Heat will also change the expected
performance of circuit breakers and fuses, which can cause
whole systems to shut down unexpectedly. So, if you have any
electronic equipment or other heat sensitive devices, you may
needHOT
cooling.
How do you get the heat out of your enclosure and away
from those critical components? There are four basic cooling
methods.
What causes all that heat?
Forced Convection Cooling
There are basically two sources that can cause the enclosure’s
internal temperature to rise above the ratings of the control
equipment.
If you have clean and cool ambient air outside of the enclosure,
then a simple forced-air system may be adequate. A system
such as a filter fan and the associated grille with the appropriate
filter may be an acceptable option.
Closed Loop Cooling
Internal Sources
The same items that can be damaged by heat may also be the
source of the heat. These include items such as:
• Power supplies
• Servos
• AC Drives/inverters
• Soft starters
• Transformers
• PLC systems
• Communication products • HMI systems
• Battery back-up systems
Other sources of heat that can cause the internal temperature
of your enclosure to rise above a desired level involve the
external environment. These include items such as:
• Industrial ovens
• Solar heat gain
• Foundry equipment
• Blast furnaces
Book 3 (14.3)
If the ambient temperature outside the enclosure is cooler than
the inside of the enclosure, then the heat can be dissipated
into the atmosphere by radiating it through the surface of the
enclosure and through the use of louvers or grilles with filters.
Closed Loop Cooling
A system that will keep the ambient air separate from the internal
enclosure air is needed if the environment is harsh, there are
wash-down requirements, heavy dust and debris or the presence
of airborne chemicals, and the ambient temperature is as high as
or higher than the desired internal temperature. Air conditioners
and heat exchangers are examples of closed loop systems.
Vortex Coolers
External Sources
EN-286
Natural Convection Cooling
Enclosures Thermal Management
Vortex coolers create a stream of cold air from a supply of
filtered compressed air. The cold air is injected into the
enclosure, displacing warm air which is exhausted back through
the vortex cooler. While not a closed-loop system, they can be
used in the same harsh environments since the cold air injected
into the enclosure is filtered.

Enclosure Cooling –
Selecting a Fan or Air Conditioner
Fan selection
To select the proper size (CFM) fan for your forced air cooling
solution, you need to determine the amount of heat to be
removed (in watts) and determine the Delta T (Max. allowable
internal enclosure temperature °F – Max. outside ambient
temperature°F).
CFM = Cubic Feet per Minute
P = Power to be dissipated in watts
CFM = (3.17 x Pwatts) / Delta T °F
Delta T = m
ax. allowable internal enclosure temperature °F – max.
outside ambient temperature °F
Fan Selection Example
A NEMA 12 Hubbell Wiegmann N12302412 enclosure
(30” high x 24” wide x 12” deep) contains a GS3-2020
AC drive (20 HP 230 volt) that has a maximum allowable
operating temperature of 104°F and is located in a warehouse
that has a maximum outside ambient air temperature of 95°F.
Power to be dissipated is stated in the specifications of the
GS3-2020 and is found to be 750 watts, so P=750 watts
Delta T = Max. operating temperature for the GS3-2020 is
104°F – Max. ambient air temperature of 95°F
Delta T = 9°F
CFM = (3.17 x 750 watts) / 9°F
CFM = 264
Choose a Hubbell Wiegmann WPF60-115BK filter fan kit
that provides 295 CFM with exhaust kit WPFA50-60BK
Air conditioner and vortex cooler
selection
To select the proper size air conditioner or vortex cooler, the
worst-case conditions should be considered, but take care not
to choose an oversized unit.
There are two main factors in choosing an uninsulated metal
NEMA rated enclosure located indoors:
• Internal heat load
• Heat load transfer
Internal Heat Load
Internal heat load is the heat generated by the components
inside the enclosure. This can be determined by a few different
methods. The preferred method is to add the maximum heat
output specifications that the manufacturers list for all the
equipment installed in the cabinet. This is typically given in
Watts, so use the following conversion:
BTU per Hour = Watts x 3.413
Example: The Watt-loss chart for the GS3 Drives shows that a
GS3-2020 AC drive has a Watt-loss of 750 watts.
Air Conditioner Selection Example
A NEMA 12 Hubbell Wiegmann N12302412 enclosure
(30” high x 24” wide x 12” deep) contains a GS3-4030 AC
drive 30 HP 460 volt) that has a maximum allowable operating
temperature of 104°F and is located in a warehouse that has
a maximum outside ambient air temperature of 115°F.
Power to be dissipated is stated in the specifications of the
GS3-4030 and is found to be 1290 watts.
Internal heat load:
BTU per Hour = 1290 watts x 3.413
BTU per Hour = 4403 BTU/H
Heat load transfer:
Heat load transfer (BTU/H) = 1.25 x 19 sq. ft. x (115°F – 104°F)
Heat load transfer (BTU/H) = 261.25 BTU/H
Cooling capacity:
Cooling capacity (BTU/H) = 4403 BTU/H + 261.25 BTU/H
Cooling capacity (BTU/H) = 4664.25 BTU/H
In this example, you are able to determine that a 5000
BTU/H unit is needed. Select a TA10-050-16-12 Stratus air
conditioner.
Note: The same calculation method is used for sizing
Stratus vortex coolers. However, in this example the
BTU per Hour = 750 watts x 3.413
BTU per Hour = 2559
cooling requirements exceed the maximum capacity of
the largest available vortex cooler.
Heat Load Transfer
Heat load transfer is the heat lost (negative heat load transfer)
or gained (positive heat load transfer) through the enclosure
walls with the surrounding ambient air. This can be calculated
by the following formula:
Heat load transfer (BTU/H) = 1.25 x surface area (sq. ft. ) x (max.
outside ambient air (°F) – max. allowable internal enclosure temperature air (°F))
Surface Area (sq. ft.) = 2 [(H x W) + (H x D) + (W x D)] / 144 sq. inches
If the example
application required the use of a vortex cooler instead
of an air conditioner, two
(2) TV35-025-4X units would
be needed.
Thermal
Expansion
Valve
Evaporator
Condenser
Note: 1.25 is an industry standard constant for metal enclosures;
0.62 should be used for plastic enclosures.
Once you have determined your Internal Heat Load and the
Heat Load Transfer, you can choose the proper size unit by
calculating the needed cooling capacity.
Compressor
Cooling capacity (BTU/H) = Internal Heat Load ± Heat Load Transfer
