5.7. Coolers
To ensure reliable operation of the compressor it is important to keep the LP and HP coolers free from deposis of
carbon and cooling water salts etc. Insufficient cooling causes excessive air temperature and progressively
increases the formation of carbon deposits.
The cooling tubes are roller expanded into tube plates at both ends.
The seals at the cooler ends are O-rings, type OF special quality. Use only manufacturer's spares. To remove
the tube bundle, first loosen the cooler covers at both ends. The whole bundle can then be withdrawn by means
of two guide rods, pushed through the tubes.
Assemble in opposite sequence.
Instal new seals.
If the cooling tubes show signs of severe corrosions or wear, the complete cooler should be replaced.
5.8. Filter
The air filter should be cleaned by means of a good degreasing agent. Blow the filter clean with compressed air
and give it a thin coating of compressor oil.
The oil filter should be replaced complete. Replacement every 1000 hours running time is recommended.
