Sigma Engineering

Sigma Engineering, established in 1988, began by representing ABB in Egypt, providing supply, engineering, and maintenance services for UPS (Uninterruptible Power Supply) and ATS (Automatic Transfer Switch) products. Over time, the company expanded its portfolio to include a broader range of power quality solutions, representing leading European companies such as Gustav Klein, Aerocom, and Eaton, becoming recognized as a leader in the Egyptian market.

In 2003, Sigma launched its manufacturing division, producing servo stabilizers, innovative static turbo stabilizers, industrial battery chargers, and digital panel meters.

Beyond power supply products, Sigma provides comprehensive after-sales services, from basic UPS and battery maintenance to full-service contracts. The company also offers professional consultation services in power quality assessment and improvement and green energy transformation.

Sigma operates from its fully owned premises in Obour Industrial City, spanning 2000 m² of land with 4000 m² built-up facilities, and is proudly ISO 9001 certified.
