Environmental aspects of development
Due to the use of highly integrated components, the number of parts has been kept to a minimum.
This results in the highly efficient use of energy in production.
Particular importance has been attached to reducing the volume, mass and diversity of metal and
plastic parts.
Front components:
PC + ABS Cycoloy GE-Plastics
ABS Novodur Bayer
Plastic components in
converter:
PC Lexan 141-R
PA 6.6
SE1-GFN1 Noryl
Insulation: PC (FR) fl Makrolon or Lexan
Rating plate: Polyester membrane
Materials free of pollutants are used for all important parts. No flame-retardants containing halogen
or insulating materials containing silicon are used.
Environmental compatibility was an important criterion in the selection of supplied parts.
Environmental aspects of production
Most supplied parts are shipped in reusable packaging. The packaging material itself is recyclable,
consisting mainly of cardboard.
With the exception of the converter housing, surface coating materials have not been applied.
The production process is free of emissions.
Environmental aspects of disposal
The unit features screw and snap-on connections that can be separated easily to dismantle it into
recyclable mechanical components.
The printed circuit boards can be disposed of by thermal processing. The percentage of
components containing dangerous substances is low.
