Riello Elettronica is a holding of companies operating in the following sectors: domestic and industrial electronics, power plant engineering and information technology, the production of uninterruptible power supplies and safety and home automation systems. It also makes use of real estate instrumental to the industry and has holdings in agricultural firms.
The core business of the group, founded and run by Pierantonio Riello, are those companies operating in the area of energy conversion and in the production of electronic uninterruptible power supplies.
In this field, thanks to Aros and Riello-Ups, Riello Elettronica is one of the top ten manufacturers in the world, with a range of products able to meet the energy requirements from the smallest personal computer to large banking systems, hospitals and airports, where operational continuity is crucial.
Production is performed in the plants in Legnago, Milan and Shanghai, recently opened together with new agency offices in Beijing and Shenzhen. Direct control in the Asian markets follows a strategy already implemented successfully in France, Germany, Spain and Great Britain and which is essential with regard to direct supplies of electronic components.

Domestic and industrial safety, home automation and pneumatic applications are the business areas developed by Riello Elettronica through the following companies: AVS, Innovatech, Gamma System and Ceimu.
AVS is the leading company in Italy for the production of alarm and anti-intrusion systems, and its products can be integrated with the home automation systems produced by Innovatech, offering a range of electronic devices that can communicate in a wireless network and connect all the house functions through intelligent terminals. Riello Elettronica is looking to the future with home automation, opening up new boundaries of environmental well-being and comfort in daily living. The home is becoming "intelligent" and can be remotely controlled via an internet connection. The use of a palmtop, a PC or a mobile phone is all that is needed to be able to control energy consumption, avoid blackouts, protect against break-ins, regulate temperature, switch on lights, open doors and gates, identify and stop water and gas leaks.
Industrial safety and pneumatic applications are designed and produced by Gamma System and Ceimu respectively. Electronic presence control sensors and photo-electric barriers are the specific products manufactured by Gamma System to monitor access to and safety of production machinery and plants in general. Servo-controls, cylinders and pneumatically-driven systems are successfully manufactured by Ceimu for applications in the field of general mechanics.
