HELMKE becomes a full range supplier for customers in the OEM and plant engineering

3 Milestones 1922 Ing. Johann Helmke and his wife found the company. The activities focus on the wholesale of electrical equipment, particularly the sale and repair of electric motors Dr. Dr. Horst Norbert Helmke joins the company, continues to run it as the sole owner from 1970 and expands stocks to include brand new high voltage motors up to 7 MW. Titus Helmke joins the company and proceeds to manage it from 2003 on. HELMKE becomes a full range supplier for customers in the OEM and plant engineering sector Titus Helmke has been the sole proprietor of HELMKE Group. Since 2011 Works Pulversheim/France Works Hannover/Germany Works Sarstedt/Germany 3
