Description

Technical product description EG-Series expander generator

Available in configurations to perfectly match your specific application requirements, the expander generators drive electrical power production from industrial processes and sustainable resources. Available in direct drive, integrally geared or externally geared, our expander generator offerings achieves the lowest cost per kilowatt power-train solution. Proven Atlas Copco technologies boost efficiency, including variable inlet guide vanes (IGVs) for continuous power production under changing environmental conditions.

Turboexpanders built to last
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  
Recovering green energy
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
Intelligent shaft gearbox design
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.
Full process control with variable inlet guide vanes (IGV)
Our variable inlet guide vanes (IGV) provide accurate process control over a wide operating range, avoiding the energy loss associated with inlet throttling control
Get the most from pressure letdown
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
