Expander Generators

Whether your plant is an isolated geothermal power station or a busy industrial plant, the Atlas Copco expander's robust construction is designed to withstand tough conditions over a long lifetime of reliable operation in the harshest work environments  

Our expander generators enable you to recover power from sustainable resources. Organic Rankine Cycle (ORC) technology, one of our key competences, unlocks a wide range of power sources including geothermal reservoirs, industrial waste heat and condensing streams

In integral gear configuration, the speed reduction gearbox features a parallel shaft and integral gearbox for efficient electricity generation. Power generation extends up to 25 MW per expander stage, with up to two stages per expander.

Our variable inlet guide vanes (IGV) provide accurate process control over a wide operating range, avoiding the energy loss associated with inlet throttling control

Gas grid systems, especially natural gas, require pressure to be reduced from pipelines so that it can be delivered for domestic use. Atlas Copco expanders enable you to recoup the energy stored in the gas pressure and turn it into extra profits
