Technical descriptionEC-Series expander compressorIn 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).

Technical description of the Compander (TM)Our Compander (TM) is designed to handle all gases and delivers volume flows of up to 480 000 m3/h over 8 stages, operating at a rated power of up to 30 MW. It’s a solution that meets key needs in many of today’s industrial processes, where energy efficiency is a major operations focus. Utilizing the full energy recovery potential for combined compression and expansion processes, the Compander (TM) merges our long standing expertise in integral gear technology and turbo expanders into one solution. It’s unique in that compressor and expander stages are housed in one gear box. You can use the energy recovered on the turboexpander side to power the compressor’s energy cycle, significantly reducing the compressor’s energy consumption (rotor drive). Our nitrogen and methane companders can be used in different LNG and chemical applications, respectively:
