Section 1 - Description
A - General
The Chicago Pneumatic Compressors contains a compressed air
unit in the form of a self contained, complete and fully tested
assembly, driven by an electric motor and enclosed in an acoustic
canopy, necessary for proper cooling of the assembly.
It is an oil-cooled, single stage, helical screw-type compressor.
There is a vertical mounted receiver for pre-separating and storing
oil and air. The air-oil mixture is then separated by means of a
separator cartridge.
Both the compressor and the motor are directly fixed on the frame
by anti-vibration pads.
B - Respect of the environment and
prevention of pollution
1 - Maintenance of the machine
Make sure that the used components of the machine (waste oil,
oil and air filters, oil separators, etc...) are disposed according to
national and local regulations.
2 - Condensate drain pipe
Make sure that the condensates (water, oil) are drained and treated
according to national and local regulations.
3 - End of life of the machine
Make sure that the machine as a whole is disposed according to
national and local regulations ( Section 6 - I ).
C - Standard equipment
In its standard version, the covered unit includes:
- Operating components:
1. A twin-screw compressor lubricated with the Fluidtech oil.
2. An electric motor : 3600 rpm (60Hz), short-circuit rotor,
voltage 208, 230, 460 V (60Hz), according to type.
3. Star-delta starting.
4. A V-Belt and pulley system.
5. An air / oil receiver complying to current regulation (Euro-
pean Directive for simple pressure vessels no. 87/404).
6. "start - stop" flow rate control by suction closing.
7. A lubrication system using the differential pressure of the
circuit, which avoids the need for an oil pump.
8. An oil separation system by means of a separator cartridge.
9. A heat exchanging system : oil and compressed air cooler
with forced ventilation.
10. A dry-type air filter.
11. An oil filter.
12. A command and control electronic board.
13. ES 3000 as standard on all fixed speed units,
14. ES 3000 as standard on all variable speed units.

- Safety devices:
1. A safety valve mounted on the oil receiver.
2. An thermal protection device for the motor, located in the
starting cubicle, to protect the motor from excessive over-
load.
3. A air temperature sensor that stops the compressor when the
temperature rises abnormally or during an oil cooling defect.
4. A pressure sensor that stops the compressor in order to
prevent any excessive rise in pressure.
- Control devices:
1. A minimum pressure valve located at the oil tank outlet,
just beyond the oil separator, which guarantees minimum
pressure in the lubrication circuit.
2. Automatic draining allowing the unit to be exposed to the
atmosphere when stopping to thus ensure empty start up
which relieves the motor,
3. An oil level gauge on the front panel (see Fig. 10),
4. An electronic controller including:
– a control keyboard,
– the main safety and control indications.
5. The compressed air output is regulated by a pressure sensor
The CP Compressors air unit has been designed, produced and
tested in accordance with the following recommendations, codes
and standards :
- machine safety: European Directive 98/37/CE, 91/368/CEE and
93/68/CEE.
- pressure vessels: European Directive for simple pressure vessels
n° 87/404/CEE.
- electrical equipment:
• electrical equipment: European Directive Low tension
73/23/CEE.
• electromagnetic compatibility European Directive: 89/336/
CEE, 92/31/CEE.
- performance levels: ISO 1217 : 1996.
- noise level : ISO 2157 + 3db(A)
- European Directive 97/23/EC " Pressure Equipment Directive ".
