Did you know?
Superior impeller efficiency
Utilizing the latest aerodynamic designs – including impellers created with computational-fluid dynamics (CFD) and finite-element analysis (FEA) – our turboexpanders provide high-efficiency refrigeration or power recovery in industrial processes
Flexibility to fit your process
From standardized expanders that expedite delivery times, to custom-engineered units for specific process needs, our team of engineers will work with you to identify the critical aspects of your project and suggest equipment choices that best meet your specifications.
Extensive magnetic bearing expertise
Available in custom-engineered and standardized designs, there are over 140 Atlas Copco expanders in operation reliably using active magnetic bearing technology. With over 8 million operating hours (and counting), these machines have validated the superior technology found in our expanders.
Full process control variable inlet guide vanes (IGV)
Variable inlet guide vanes (IGV) ensure optimal flow rates, especially when changing on-site conditions call for immediate adjustments. They handle changes in flow levels as low as 10% of design point and up to 125% above
Constructed to withstand the elements
Turboexpanders are designed for the most demanding conditions, including offshore marine environments, harsh desert or cold weather locations, outdoor unprotected installations and unattended sites. In addition, our package designs are customized to fully meet all hazardous areas (Division 1/Zone 1, Division 2/Zone 2) and local codes (CSA, ATEX, etc.)
