HOW AN ORC POWER MODULE WORKS

An Organic Rankine Cycle (ORC) Power Module works like a steam engine, but uses a working fluid that boils at a much lower temperature than water. That lets it make electricity from low-grade heat that would otherwise be wasted.

1. Heat in

Hot water from your process, 65–150°C, boils a low-GWP working fluid in the evaporator.

2. Expander generator

The vapour spins a BITZER twin-screw expander. It shares a sealed housing with the generator, so there is no shaft seal to leak.

3. Power out

A grid-tied induction generator exports 3-phase power. Leftover heat leaves through the condenser for drying or space heating.

PROVEN BEFORE IT SHIPS. SUPPORTED FOR LIFE.

Every Power Module passes a Factory Acceptance Test at its sold design point before it leaves the line. Once it is on site, our engineers service and maintain it alongside the rest of the UK fleet.

â–   Factory Acceptance Testing against your quoted performance

 

â–   Installation support and commissioning

 

â–   Planned servicing and maintenance, including expander generator swaps
