QEI's multifunction gateway systems are designed with standard hardware and software modules, and are assembled and customized to form integrated systems that meet the specific operational needs of each customer.

QEI is a full service company, with the engineering, manufacturing, training, and service personnel to support each customer's SCADA requirements from inception to completion. And we are small enough to have a keen interest in each customer's satisfaction. Our ISO 9001:2015 certification covers QEI's software and hardware development, project management, engineering, manufacturing, testing, and support services.


In 2011, QEI Inc. was acquired by Crompton Greaves Limited (CGL), a flagship company of the US$ 4 billion Avantha Group, is a US$ 2.25 billion India-based multinational in the electrical Transmission & Distribution business and a global supplier of a wide range of products and services to the utility industry. The key component of this agreement is that QEI will become the platform for CGL’s North American automation operation and will maintain its current location and organization with the same management structure. We firmly believe that joining the CGL organization will bring us the corporate strength needed to maintain our leadership position in the fast expanding utility, renewable and transit markets and continue to provide world class products and services to our customers.
