1. Introduction
The Meech Air Technology Stainless Steel Cabinet Cooler uses compressed air
to provide a cold air source which stops industrial cabinet/panels or enclosures
overheating and prevents ingress of contamination such as dust or moisture.
The Cabinet Cooler Unit (excluding Solenoid Valve and Thermostat) is intrinsically
safe, and requires virtually no maintenance. They have no moving parts making them
ideal for harsh environments.
Cabinet Coolers can be used with or without electrical thermostats and solenoid
valves (Cabinet Cooler System). These are used to regulate the cooling within an
enclosure.
This operating manual covers products:

2. Safety and Inspection
Meech Cabinet Coolers are packed carefully at our factory. Nevertheless, we
recommend careful examination of the carton and contents for any damage.
To protect yourself and others when using compressed air, you should be aware of the
following general safety guidelines:
Warning – When compressed air is misused, it can cause serious injury or
even death.
Never point an air hose at anyone in fun or to remove dirt from clothing or the
body.
Never use compressed air without adequate eye and ear protection. Use
safety glasses with side shields or goggles and ear protectors.
Before attempting to disconnect a hose from an air line, the air should be cut
off, and the remaining air bled from the line.
Keep air hoses off the oor where they become tripping hazards and are
subject to damage by vehicles, doors, and dropped tools. If possible, suspend air
hoses from overhead.
Please be aware of the following safety guidelines specic to the Cabinet Cooler:
Cabinet Coolers create both hot and cold air so parts of the unit will become hot.
Do not operate the Cabinet Cooler at compressed air pressures above 11 Bar
(160 psi)
Compressed air temperature must not exceed 55°C
Ambient operating temperature must not exceed 66°C
Ambient operating temperature can not drop lower than -10°C

3. Maintenance
The Meech Cabinet Cooler has no moving parts. Clean compressed air moving
through the Cabinet Cooler will not cause wear on any of the components.
Occasionally, dirt, water or oil may enter the cooler from the compressed air supply.
This could hinder the performance. If this happens simply take the unit apart, clean
the parts with soapy water, allow drying time and then reassemble.
When reassembling ensure you tighten all the components. If the parts are not
tightened correctly, the coolers performance may be affected. Also, please ensure the
generator is tted. At the same time the element in the air lter should be changed.

4. Compressed Air Supply
It is recommended to use a 5-micron (or smaller) lter to remove water and dirt from
the compressed air supply. A 5-micron lter will remove 99% of foreign material from
the air supply; the use of an oil lter with an effective ltration of 0.01 ppm will remove
the oil droplets for an even cleaner compressed air supply.
Failure to use a lter may cause clogging and freezing of the compressed air line and
the components within the Cabinet Cooler.
When the temperature of the compressed air within the Cabinet Cooler reaches 0°C
the water vapour in the air will start to freeze. This could potentially cause a problem
with ice clogging the orices of the Cabinet Cooler.
In this instance an air dryer must be used to lower the dew point and keep water
vapour out of the air line. A dryer rated at -19°C will produce a dew point low enough
to eliminate the water vapour freezing.

5. Compressed Air Lines Sizes
Figuring the correct pipe size for your compressed air system is an important task.
Pipe that is sized too small can create big pressure losses and reduce operating
efciency.
Many people who plan the piping never consider the ttings or the future.
FITTINGS: Every pipe tting creates a certain amount of increased frictional air loss
that is equal to a specied length of pipe. Any turns in the pipe at ttings, ells, tees,
and valves increase pressure drops even more.
FUTURE: Are you planning to add more equipment in the next year or two? Then
plan for larger piping now. Since the material costs in piping are low compared to
installation or replacement cost, it’s wise to select pipe of an adequate size. If there
is any doubt that a pipe size may create a pressure drop, use the next largest size.
Remember that an oversize pipe compensates for possible scale build-up and
provides for future expansion of the overall air system.
Steps to calculating overall piping size for your compressed
air system:
1. Determine your air compressor’s maximum CFM.
2. Draw a piping schematic and show all pipe ttings, valves, etc.
3. Measure and write the corresponding lengths of pipe on your schematic, then
total the length of all straight pipes needed and note that on your schematic.
4. Using TABLE 1 (over page), nd your compressor’s CFM number on the far left
column, and then go to the right until you see the column header with nearest
length in feet to your total pipe length. Find where the CFM & PIPE LENGTH
intersect on the chart and it will show the recommended pipe size for that length.
5. Take that pipe size to TABLE 2 and use the table to nd all the EQUIVELENT
