BERG KOMPBERG BSDF 30 - Handling Wastes Produced While Operating the Compressors; Pressure Switch

Operating and Maintenance Manual 09/2019 – part I
Screw compressors

- Check the oil level: replenish the missing oil quantity up to the maximum level.
- Dispose the waste oil in accordance with the applicable regulations.
In the screw compressors there is used the PNEUMOIL ST68 synthetic air compressor oil.
The compressor oil used must meet the following basic specifications:
Kinematic viscosity at 40°C
68 cST (mm
2
/s)
Flow temperature
< - 45 °C
Flash point
min. 250 °C
In addition, the oil must:
- be resistant to oxidation,
- have very low susceptibility to emulsification,
- have very low foam ability,
- provide good corrosion protection,
- have improved lubricating properties.
When oil is changed, you must absolutely maintain the same parameters.
Otherwise, the machine may get damaged.
Mixing of different oil types is not allowed.
Always use the same brand and type of oil for topping up.
RECOMMENDATIONS CONCERNING OIL
BERG KOMPRESSOREN GmbH recommends to use only the PNEUMOIL ST68 synthetic
oil.
As the compressor manufacturer we have selected the oil with optimal properties to ensure
the proper protection of the compressors, maintain technical parameters and prolong their
life.
The testing showed that the oil recommended by BERG KOMPRESSOREN GmbH
provides longer effective compressor operation and increases overall system efficiency.
The PNEUMOIL ST68 synthetic oil helps maintain a constant delivery of compressed air
necessary for the efficient system operation e.g. by means of five times faster air removal
(which improves lubrication and prevents damage caused by the cavitation phenomenon)
and more than twice faster water separation (which provides effective protection and
lubrication).
8.3.8. Handling wastes produced while operating the compressors
The condensate from the compressor, tank or compressed air treatment equipment must
not be drained directly to sewage system. It should be disposed in accordance with
the applicable waste management regulations; waste code 13 05 07.
Waste oil should be disposed in accordance with the applicable waste management
regulations; waste code 13 02 05.
Oil filters and oil filter cartridges should be disposed in accordance with the applicable
waste management regulations; waste code 16 01 07.
8.3.9 Pressure switch
The pressure switch is connected with a conduit to the outlet connection (at the minimum
pressure valve) of the compressor or to the air receiver.
You are not allowed to change the maximum pressure setting above the value given on
the identification plate of the compressor and to change the minimum pressure below 5
bar.
Pressure switch settings:
− Minimum pressure differential– 1.5 bar,
− Minimum cut-in pressure – 5.0 bar,
− Maximum cut-out pressure –according to the identification plate.
