Energetic air purification<br />
through innovative heat<br />
pump technology<br />
Die casting processes generate huge<br />
amounts of gases and vapors, which<br />
consist of aerosols and fine smoke particles.<br />
Due to the occupational safety<br />
and environmental protection, these<br />
must be removed from the work area.<br />
For some foundry this is not an easy<br />
task, because each foundry is designed<br />
differently and standardized solutions<br />
do not always provide the optimum<br />
solution for individual plants.<br />
KMA Umwelttechnik GmbH, Königswinter,<br />
Germany, is specialized since<br />
more than 25 years on the development<br />
of energy-saving and environmentally<br />
friendly methods of exhaust<br />
air purification in foundries. KMA offers<br />
to each exhaust air problem the<br />
best solution. Today´s most energy efficient<br />
method of exhaust air treatment<br />
is the recirculating air mode. Due to the<br />
high filtration efficiency of the KMA<br />
electrostatic precipitators the purified<br />
air often gets discharged back to the<br />
workplace. Thus, the air circulates in<br />
the hall and compared to the exhaust<br />
air mode excessive heat loss can be<br />
avoided during the heating period. Accordingly,<br />
this method offers the greatest<br />
potential for energy savings. However,<br />
certain production processes or<br />
the company´s corporate philosophy<br />
in general does not always enable a recirculating<br />
air mode. In addition, peripheral<br />
devices – such as sprayers, furnaces<br />
and presses – sometimes limit the<br />
space around the die casting machine.<br />
Therefore, installing extraction devices<br />
such as hoods sometimes become impossible.<br />
But even in such cases an energy-efficient<br />
air purification solution<br />
needs to be placed.<br />
This view is what KMA Umwelttechnik<br />
is standing for and that’s the reason<br />
why they developed for such applications<br />
an energy-efficient air filtration<br />
system, which operates in an exhaust<br />
air mode. The new system with a highly<br />
efficient heat recovery system enables<br />
by the use of 1 kW of energy (electricity)<br />
to achieve more than 20 kW of<br />
heat output due to utilizing the waste<br />
heat. The high efficiency is based on an<br />
innovative heat pump technology,<br />
which will be introduced at the GIFA<br />
exhibition <strong>2015</strong>.<br />
