About Us


O.E.N. ENTERPRISES Ltd was founded in 1970 as a privately owned company and was, at that time, based on various Thorn EMI agencies. O.E.N. represents these and other high technology companies from UK, Europe and the USA. The customer base includes industrial, process and mining industries as well as medical facilities, research institutions and defense Industries.

O.E.N. continues to specialize in high technology services and solutions; however, has expanded the product base to meet the growing needs of the client base. O.E.N. continues to support the product footprint via a dynamic technical team.

Since 1998, O.E.N. has acquired a number of new agencies. The new agencies are synergistic with both the historical product and current customer base. O.E.N. remains committed to maintaining high levels of technical expertise. Customer support is the key to O.E.N.’s success and sustainability.

O.E.N. Enterprises (Pty) Ltd, due to its ownership, is now a level 3 BBBEE contributor.
