Our Background

SON Srl was established in 2004 with a foundation of more than 30 years working experience in the power generation market and extensive knowledge of industrial boilers.  As one of the first dealers of large scale ORCs in Italy, SON recognized a movement towards distributed power generation among smaller-sized generators in a new market:  WASTE HEAT TO ENERGY.

Our Research

In pursuit of new technologies, in 2012 SON Srl began to collaborate with HELIEX POWER Ltd, which was in the process of developing a new steam screw expander capable of working with wet (saturated) steam on a continuous basis.  SON supported HELIEX POWER with field testing of the machine in Italy and after further research and development, the first commercial machine was ready to be installed at a steel factory in 2013.
