GENERAL INSTRUCTIONS
When a Cabinet Cooler is required all potential sources of heat generation should be taken
into account. Example: When an enclosure is in direct sunlight installing a sun shade and
possibly thermal insulation would reduce the solar heating considerably.
If a Cabinet Cooler is required the following must be considered.
Principle of Operation
The Cabinet Cooler (Vortex type) works by using a compressed air supply and spinning the
air into a chamber at very high RPM. This splits the air into a hot and cold fraction. The hot
fraction of air is exhausted outside the enclosure. The cold fraction is vented into the
enclosure and ultimately has to be vented out of the enclosure.

WARNING
The device adjuster screw located beneath the air silencer (muffler) has been pinned to limit
the maximum exit air temperature. Any un-authorised adjustment of the ‘slotted’ valve will
automatically invalidate the use of this product in a hazardous area.
The unit must be fixed inside an enclosure with a minimum protection of IP4X.
When the Cabinet Cooler is installed on to the enclosure the Cooler/muffler must be
replaced onto the exhaust of the Vortex Tube which is located in the Hazardous Area, in
such manner that can only be removed by the use of a tool.

APPLICATION SUITABILITY
•
•
As the Cabinet Cooler displaces air care should be given on installations where movement
of dust may be an issue, (Zone 21 & 22 or Class II).
The following materials are used in the construction of Cabinet Cooler.
If substances that will adversely affect any of these materials are present in the surrounding
environment, please consult Expo Technologies for further guidance.
Materials of construction:
• Stainless Steel
• Mild (carbon) Steel
• Brass
• Copper
• Aluminium
•
•
5
•
•
•
•
Polyamide
Epoxy Resin
ABS
PVC
This equipment is designed for use under normal industrial conditions of ambient
temperature, humidity and vibration. Please consult EXPO before installing this equipment
in conditions that may cause stresses beyond normal industrial conditions.
The Cabinet Cooler is not silent in operation.
INSTALLATION
General Notes
When installing a Cabinet Cooler into a Pressurized Enclosure the following issues should
be considered.
•
•
•
•
A second Relief Valve unit may be required to exhaust the cold fraction entering the
Pressurized Enclosure. This second Relief Valve unit will need to be set at a higher lift off
pressure than the Relief Valve unit supplied with the MiniPurge Control Unit.
This is to
ensure that the operation of the MiniPurge is not interfered with.
The second Relief Valve unit must also be capable of exhausting the full flow rate of the
cold fraction. This is typically between 20-80% of the air supply dependant on setting at
time of commissioning.
The MiniPurge must control the operation of the Cabinet Cooler by way of the purge
complete signal. The MiniPurge must go through a purge cycle before the Cabinet Cooler
receives either a supply of compressed air or electrical power.
This will prevent the
MiniPurge considering the cold fraction as the purge flow which would be incorrect. The
solenoid valve will obtain its power once the purge time has elapsed.
Cabinet Cooler assemblies supplied by Expo have a solenoid valve to control the
compressed air supply. In addition a thermostatic control is included and a one way air
valve fitted to the cold fraction.

The one way air valve is to prevent the enclosure losing pressure when the Cabinet Cooler
is not in operation. If a customer is to install a Cabinet Cooler themselves into an Expo
Pressurized Enclosure that has already been certified by Expo then Expo requires:
documents, drawings, circuits etc, recording this addition so that we can issue an
amendment to the overall certificate. This may incur additional costs.
To install the Cabinet Cooler refer to the general assembly drawing for overall dimensions.
Drill a hole on the top face of the enclosure, the one way valve must be vertical.
It is possible to mount the Vortex tube in the side wall, although this is not the preferred
option.
Unscrew the hot air exhaust muffler and remove the gland.
Fix gland into the drilled hole.
Now insert the vortex tube through the gland and tighten the gland up to hold the Cabinet
Cooler in place.
Now replace the hot air exhaust muffler and place supplied label adjacent to the muffler on
the outside of the enclosure.
The temperature sensor can now be positioned within the enclosure. This could be on a
specific device or in the top of the enclosure where the temperature will normally be at it’s
greatest.
The wiring and pneumatic pipe work can now be fitted.
COMMISSIONING
Always ensure that there is adequate exhaust and pressure relief provided for the
enclosure. If this is not provided the enclosure will become over pressurized and may
operate outside of its Test Pressure specification and possibly become a hazard in itself.
General Notes
Compressed air supply:
The air supply temperature should not exceed 40ºC, 104ºF or 55ºC, 131ºF, depending on the
model. Solar shading or thermal insulation of air supply pipe work may be required.
Air supplies are plagued with condensed water vapour and droplets in the air lines. This
condensation leads to rust and dirt in the air lines. Also, some compressors will allow oil or
oil vapour to enter the air line.
It is important that the electrical equipment within the Pressurized Enclosure is not
contaminated. Small orifices within the Cabinet Cooler may become clogged with rust, dirt
and water droplets. A 5 micron filter will separate 99% of foreign material from the air
supply, allowing virtually maintenance free operation. The use of an oil filter with an
effective filtration of 0.01 micron will remove the oil droplets for an even cleaner air supply.
Keep in mind that the current line or hose might contain water, dirt or oil and should be
blown out before installation. Also, pipe thread sealant or tape must be carefully applied to
avoid clogging product orifices.
When the temperature of the air inside the Cabinet drops to 0ºC (32ºF), the water vapour in
the air will start to freeze. If this poses a problem with ice clogging the orifices of the
generator inside the tube, an air dryer must be used to lower the dew point to keep out the
water vapour. An air dryer rated at -19ºC, 2ºF will produce a dew point low enough to
eliminate the water vapour freezing in the orifices of the generator.
•
•
•
The installation of the electrical connections shall be inspected for correct installation before
the unit is put into service.
The Cabinet Cooler has the temperature setting, factory set to 20ºC, 86ºF
If the customer wishes to change this then the adjustment resistor is shown on the drawing
provided. This does not have an indexed scale.

The Cabinet Cooler can now be operated. Once a purge cycle has been completed the
Cabinet Cooler will become active. As soon as the sensor detects the set temperature has
been exceeded the Solenoid Valve will open and the Cabinet Cooler will operate.
Air will be vented from the Hot air Muffler and out of the enclosure Relief Valve.
The Solenoid Valve will close once the set temperature has been reached.
MAINTENANCE
The Cabinet Cooler has no moving parts. Clean, compressed air moving through the tube
will not cause wear on the parts and will provide the same service for an indefinite period of
time.
Occasionally, dirt, water or oil may enter the tube from the compressed air supply and
hinder the performance. When this happens, simply take the unit apart, clean the parts, and
reassemble, tightly replacing the cold end cap to properly seat the generator.
The Solenoid Valve is also maintenance free and should be replaced if a fault does occur.
The encapsulated fuse fitted inside the IP66 box using double sided sticky tape can be
easily changed if it is required.
The following maintenance routine should be repeated once a year, to check that the Vortex
Cooler is operating correctly.
Warning: Do not open enclosure when an explosive atmosphere is present. Only carry out
this test in a safe environment.

Equipment Required
As a minimum requirement the following will be required.
Vortex Cooler
110Vac, 250Vac or 24Vdc Power Supply (dependent on model)
7barg Air supply
Digital thermometer
Heat source, i.e. hot water (temperature above 25ºC).
Note: Heat source is only needed if the ambient temperature is below 20ºC.
Procedure
Only complete the following procedure if trained and suitably skilled in the safe use and
testing of 0-250V electrical equipment and pneumatic equipment rated up to 10barg. Ensure
precautions are taken when dealing with the heat produced by the Vortex Cooler
(specifically the silencer/muffler) after testing.
7.1
Ensure that all wires are connected and terminated properly.
7.2 Ensure the pressure of Air supply to the Vortex Cooler is set to 7barg. Ensure Air supply
stays switched off at this stage.
7.3 Place the temperature probe of Digital Thermometer inside one of the exhaust holes of the
Hot air exhaust Muffler. Secure the wire of the temperature probe to the Vortex Cooler so it
cannot move during the test (use of PTFE tape is recommended).

7.8 Turn Potentiometer anticlockwise until the Vortex Cooler turns on. When the Vortex Cooler
is activated the Output solenoid LED lights up red. Check that the Vortex Cooler is
functioning by turning the Potentiometer back and forward causing the Vortex Cooler to
turn on and off consequently. Then keep the Vortex Cooler turned on.
Warning: While the Vortex Cooler is activated, please ensure that suitable PPE is
being used due to the loud noise generated.
The Vortex Cooler will start only if the ambient temperature is above 20ºC. If the
Vortex Cooler has started go to point 10.
If the Vortex Cooler fails to start consult Expo Technologies or your local representative.
7.9 Remove the Temperature sensor of the Vortex Cooler
from the enclosure wall. Pour water heated above
55ºC into a safe container. Dip the Temperature
sensor into the water container. Keep the
Temperature sensor in the hot water until the Vortex
Cooler turns on. While the Vortex Cooler is activated
the Output solenoid LED lights up red. If the Vortex
Cooler fails to start consult Expo Technologies or
your local representative.

Warning: While the Vortex Cooler is activated, please ensure that suitable PPE is
being used due to the loud noise generated.
If the Vortex Cooler fails to start consult Expo Technologies or your local representative.
7.10 Run the Vortex Cooler until the temperature of the hot air, on the exhaust muffler, is in a
steady state (Max. 10 minutes). If the measured temperature of the outlet air flow is over
65ºC, the Vortex Cooler is correctly operating. If it is below 65ºC, check that the Air supply
pressure is still 7 barg. If the Air supply pressure is below 7 barg, temperature is expected
to be below 65ºC and the Vortex Cooler will not be running at full capacity.
7.11 Turn off Air supply to Vortex Cooler.
7.12 Remove the temperature probe from the Hot air exhaust Muffler.
7.13 If steps 6-8 have been skipped, remove the Temperature sensor from the hot water and
replace it back to its original position. Otherwise, readjust the arrow on Potentiometer to
the required set-point -the original position recorded on chart-, and replace the cover of the
PCB housing of the Vortex Cooler.

FAULT FINDING
•
•
•
•
•
•
9
The most common fault is a lack of air supply due to either low air supply pressure or poor flow
rate. Poor flow is because of too small pipe work, long pipe lengths or small fittings.
Occasionally dirty or very wet air causes ice build up within the enclosure, leading to
intermittent operation and water within the enclosure.
If the system does not work at all check the fuse has not blown.
Ensure the temperature setting has not been tampered with.
Ensure the air exhausts are not blocked.

Description
The Expo Technologies Cabinet Vortex Cooler provides cooling for enclosures
using compressed air. Cooling may be required either to remove heat generated
by the contents of the enclosure, or to compensate for high ambient temperatures.
There are two types of Cabinet Vortex Coolers. Models AVC-0000-001, AVC0000-002 & AVC-0000-003 have been designed for use in Zone 1 and Zone 2
(Categories 2 and 3), Group IIC applications in Enclosures protected by
Pressurization types ‘px’, ‘py’. or ‘pz’. Models AVC-0000-006, AVC-0000-007 &
AVC-0000-012 have been designed for use in Zone 2 (Category 3) applications
and has been assessed as Ex nA mc IIC (refer to EXPO 09ATEX1122X).
The Cabinet Vortex Cooler is provided with a solenoid valve and a temperature
sensor.
11)
Specification
Air supply
4 - 7 barg
Supply voltage
110 - 230 Vac or 24 Vdc
Cooling capacity
400W or 1500W @ 7 barg
Ambient temperature range –20ºC to + 40ºC or –20ºC to +55ºC
as marked on the equipment.
12)
Special conditions of safe use
The device adjuster screw located beneath the air silencer (muffler) has been
pinned to limit the maximum exit air temperature. Any alteration will invalidate this
certificate.
The maximum supply air temperature shall not exceed 40ºC or 55ºC depending
on the model.
The Cabinet Vortex Cooler must be installed to conform to the instructions in the
user manual. Measures shall be taken to limit the enclosure pressure to safe
levels.
Once the Cabinet Vortex Cooler is installed, the silencer (muffler) shall be fixed
onto the unit so that it can only be removed by the use of a tool.
It is responsibility of the user to ensure that the Cabinet Vortex Cooler is
appropriately earthed to the enclosure.
For use in Zone 1 (Category 2) applications, the user shall ensure that the
maximum regulator pressure, even under fault condition, does not exceed 7 barg.
13)
Hazards identified
The hazard presented by hot gases released into the potentially explosive atmosphere
and hot metallic surfaces on the Cabinet Vortex Cooler are prevented by limiting the unit
for use in a specific T Class, as marked on the label of each unit.

Hazards identified (Continuation)
The hazard presented by potential electrical sparks that could escape into the
potentially explosive atmosphere through the Vortex tube is prevented by a
tortuous path of minimum two 45 degree bends. Additionally, the silencer (muffler)
may have double brass mesh which prevents the discharge of metal chips,
abrasive grits, dusts and other contaminates.
Due to the movement of air through the Cabinet Vortex Cooler static electricity
could be produced and ignite the potentially explosive atmosphere. A special
condition of safe use for this certificate states the user shall ensure the Cabinet
Vortex Cooler is sufficiently earthed to the enclosure ensuring that any static
charge created is discharged safety to the enclosure.
