Waste Heat Recovery


For several industries, the recovery of waste heat, in the form of heat or electricity, represents an economic saving. Sangalli Technologies' core business is the design and construction of energy recovery solutions. Sangalli Technologies is the first company, on a worldwide basis, that installed an ORC (Organic Rankine Cycle) heat recovery system at a float-glass manufacturing plant. This technology is particularly suitable for low/medium heat power consuming companies or in cases where the waste heat temperature exceeds the optimal range for the classic steam cycles.


In such systems, a crucial role is played by heat recovery. The exchangers must be suitably sized and must use the best available technologies to prevent dust deposits on the exchanger surfaces or the clogging of the ducts. The recovered heat energy is then reused through distribution circuits of either hot or superheated water or thermal oil (in case of higher temperatures).


Sangalli Technologies aims to:

  • Assess technical and economic feasibilities, in order to validate the project, whether aimed at electrical production or thermal energy;

  • Design and provide general and detailed drawings, with the correct size of the plant and each machinery;

  • Licenses and permits.
