 Quantima technology helps maintain high quality
standards at Daimler Benz
As part of the process of modernising one of its two
compressed air stations, the Mercedes Daimler Benz
truck plant in Wörth replaced two ageing piston
compressors with an energy-saving Quantima Q-52
compressor from CompAir.
Following an independent engineering audit, the
machine is now delivering up to 5% more energy
savings than originally anticipated.Energy efficiency - a top priority
Daimler decided to replace the compressed air
station, as the existing piston machines were
becoming expensive to maintain and could not offer
the same efficiency as newer models.
Energy efficiency was a major factor in the choice
of compressor as Matthias Kreiner (Dipl.-Ing. (FH)),
planning engineer with responsibility for compressed
air and industrial gases for Daimler explains; “We
have always been mindful of the energy usage and
costs involved in our processes. For example, there
are energy meters fitted at both compressed air
stations, so we know the cost of running the
compressed air system as a whole as well as the cost
per cubic metre.”Maximum savings
Following a visit to a pilot user in Finland,
Daimler’s planning department opted to replace the
two existing piston compressors in the 6-bar network
with one Quantima compressor
Each of the three machines in the compressor station
is linked to a desiccant dryer.
In a conventional desiccant dryer, the desiccant
material is often regenerated by blowing
externally-heated hot air through it. The Quantima
installation differs by using the hot air generated
from the second stage of compression to regenerate
the desiccant, which would otherwise be lost as
waste heat .
This is enabling Daimler to make significant energy
savings and the overall efficiency of the compressor
station is improved again.Exceeding specifications
Following installation, an independent engineering
consultancy tested the performance of the compressor
station. The results were even better than CompAir’s
original forecasts. Energy efficiency was up to 5%
higher and the air quality also exceeded
specifications, with low residual moisture content
after drying: at average ambient temperatures a
pressure dewpoint of around 40°C is achieved.
Reliability and efficiency assured
The Quantima compressor is monitored by the
intelligent Q-Master control system, which
continually records and checks all system
parameters. The system is connected online to a
central CompAir control room enabling the company to
offer Daimler its comprehensive Q-Life preventive
maintenance package. Combined with ongoing remote
maintenance, this provides high compressor
reliability with a ten-year warranty.
