The ETC® operating principle
Through the process of catalytic oxidation, ETC® converters
actively transform the oil and hydrocarbons in compressed
air into water and CO2
. ETC® Converter continuously supply
Class 0 compressed air, in accordance with ISO 8573-1, with
a residual oil content of < 0.0025 mg/Nm³ as well as an oil
free condensate.
With its catalytic technology for the treatment of com
pressed air, ETC® provides a technical solution that has been
successfully used for many years in the auto motive and che
mical industries.

For compressed air upstream of a converter that has an oil
content of max. 200 mg/Nm³, ROTORCOMP® guarantees
oil-free Class 0 compressed air downstream of the converter.
In contrast to conventional filter systems (e.g., activated car
bon), the air quality is constantly maintained. Saturation and
the risk of breakthrough by hydrocarbon compounds are
reliably prevented.
In contrast to oil-free compressors, the compressed air qua
lity does not depend upon the hydrocarbon content of the
ambient air.
The operation of the catalytic converter is independent of
the temperature and humidity of the compressed air to be
treated
