A significant amount of thermal energy is generated as a by-product in the process of electricity generation. This free waste heat can be utilized through special equipment and can be delivered to the production site as useful heat in the form of steam or hot water (90 °C). They can be used in the production process all year round or can ensure the heating of the building in the winter. This is a process called cogeneration.

This free waste heat can be transformed also into cooling energy through absorption chillers, in the form of chilled water (7 °C). It can cool down the production equipment all year round or can ensure the air conditioning of the building in the summer. This is the process of trigeneration. In order to obtain this free waste heat, we need to generate electricity on-site from different sources such as:

natural gas, CNG, LNG, LPG,diesel, biomass, biogas.

REC+: Combined Heat & Power

REC+(Recovery Energy Cycle) is a modern and innovative cogeneration - trigeneration (CHP - CCHP) that simultaneously produces electricity and thermal (heat) and/or cooling energy, in a range between 20 to 2000 kW.
Rec+ is a custom made and assembled according to customer’s requirements in our Italian factory into a special and transportable BOX, so it can be delivered “ready to use” anywhere in the world.
