EcoCVac by Dürr Ecoclean – innovative dry cleaning without compressed air
Intermediate cleaning of powertrain parts with over 50% energy
savings and high process reliability
Monschau (Germany) / June 9th, 2015 – Machined powertrain components
undergo intermediate cleaning to safeguard the quality of subsequent
process steps. This is typically done by means of compressed air, which
must be generated at a high expense of energy. With their new EcoCVac,
Dürr Ecoclean offers an effective dry cleaning system that eliminates the
need for compressed air. Apart from delivering enhanced process reliability,
the system can provide energy savings of more than 50 percent. As
maintenance of the working chamber is minimized, it also improves the
machine availability.
Modern engine and transmission manufacturing lines are designed for maximum
productivity and economic efficiency. Accordingly, any cause of interference with a
downstream process must be eliminated. This makes it mandatory that engine and
transmission parts such as, e.g., cylinder heads, engine blocks and transmission
housings
undergo
cleaning
operations
between
machining
steps.
Such
intermediate cleaning is often performed by cleaning machines using compressed
air. A benefit of this method is that the part is cleaned 'dry'. On the downside,
however, generating the compressed air supply is very costly. Moreover, the chips
and machining fluid residue adhering to the product are merely blown off – i.e.,
allowed to spread around in the work chamber, which will therefore become
contaminated quickly. This, in turn, increases the risk of re-contamination of the
product, with the possible result of impairing the next processing step.

Vacuum suction without compressed air in short cycles
With its innovative EcoCVac pre-cleaning and intermediate cleaning system, Dürr
Ecoclean of Monschau/Germany has overcome these drawbacks. The equipment
relies on the newly developed vacuum suction technology. This ensures that
contaminants will be removed not just from the part but also from the work
chamber within a mere 1.5 to 3 seconds of process time.
The EcoCVac system comprises a pressure vessel in which a vacuum is
maintained permanently. This vessel is connected by a pipe to the vacuum
chamber in which the part is placed. Once the chamber is closed, a powerful
airflow is directed through it, thereby 'entraining' the chips sticking to the part and
taking them into the vacuum vessel. A chip clean-out device integrated nearby
separates chips and emulsion, allowing both to be discharged separately via a
collecting bin and a flume, respectively.
More than 50 percent energy savings
In the development of the EcoCVac system, resource efficiency was a prime
concern. As a result, the system affords a much-reduced energy consumption as
compared to compressed-air type equipment. Assuming a compressed air
consumption of 2.5 Nm³ per part at a price of 1.26 euro cents per Nm³, the cost of
one compressed-air blowing cycle amounts to 3.15 euro cents per part. With the
new vacuum dry cleaning process, an electric power input of 0.139 kWh per part is
needed. At an estimated electricity price of 10.88 euro cents per kWh, power costs
of 1.51 euro cents per part will thus be incurred. This is equal to a cost reduction by
more than 50 percent.
Optimized process reliability and availability
In addition to the obvious cost benefits, the EcoCVac shines with its improved
process reliability. As the chips are removed not only from the part but also from
the work chamber, the risk of re-contamination is minimized. The chamber must
hence be cleaned less often, and at a clearly reduced cost and effort. Moreover,
unlike conventional compressed-air systems, there are no nozzles to be aligned
relative to the part, e.g., during commissioning or after a collision. The system's
availability rate is thus further improved.

The parts are cleaned in a vacuum chamber through
which a powerful airflow is passed. This airflow not just
reliably removes contaminants adhering to the part, but
also conveys them out of the work chamber.
