US-based ElectraTherm’s patented Organic Rankine Cycle system has been commissioned at a biogas plant in Slapanov, Czech Republic, representing its second collaboration with biogas plant constructor EnviTec.



ElectraTherm, a specialist in small-scale waste heat to power generation, and its distributor, GB Consulting installed an ElectraTherm Green Machine to generate additional on-site power and increase overall energy efficiency.

To-date the machine has demonstrated greater than 98% availability.

The biogas power facility already has a GE Jenbacher 700 kWe engine, fuelled by manure and corn biogas.

The Green Machine gets its heat from a water loop extracted from the Jenbacher’s jacket water and exhaust gas at 100°C.

The machine produces 25-35 kWe, and excess heat is further utilized to supply heat to local buildings, assist in the digestion process and to dry wood.

This latest installation marks ElectraTherm’s ninth in the Czech Republic.
