With thousands of reference units worldwide, Atlas Copco Gas and Process can design a turboexpander to your specific quality and industry standards. We are experienced in ISO quality certification, as well as API, ANSI, IEC, NEC, ASME, BS500 and beyond.
Technical description EC-Series expander compressor

In compressor-loaded expanders, the expander is loaded by a single-stage centrifugal compressor through a common shaft. It’s a design that powers a wide range of applications. And because the turboexpander is skid-mounted with its auxiliary support system, it simplifies transport and reduces installation time and cost. Providing inlet pressures of up to 200 bar (a) and with a rated power of up to 23 MW, our EC-Series turboexpanders handle all industrial gases and hydrocarbon gas mixtures, including condensing streams. Variable inlet guide vanes (IGV) used in our EC-Series ensure optimal flow rates even when your process conditions change well beyond the original design point. The EC-Series is available in compressor-load configurations using either oil bearings or active magnetic bearings (ECM).
