A challenge like this fits Stahl / Electromach per-
fectly. A combination of manufacturing and assem-
bling is our strength. We are able to develop and
certify, if necessary, new products and eventually
implement them in the project. Stahl / Electromach
is a system-house specialized in the design, en-
gineering, manufacturing, assembling, testing, cer-
tifying and commissioning of electrical distribution
and control systems for use in a hazardous area.
