- Page 2 To this end, we operate an Environmental Management System (EMS) which is certified to the International Standard ISO 14001. The electronic variable speed drives manufactured by LEROY-SOMER have the potential to save energy and (through increased machine/process efficiency) reduce raw material consumption and scrap throughout their long working lifetime.
