Customers routinely send their C16 to C30 compressors to the Houston depot for overhaul following a failure or for routine cleaning if fouling is evident. Larger units are normally dismantled in the field and damaged rotors or barrel casings sent to our dedicated facility in Hengelo in the Netherlands, this facility has full overhaul and refurbishment capability.
Other OEM Compressors
EthosEnergy can inspect, repair, reverse‐engineer and rebuild centrifugal compressors from virtually any OEM, including stationary elements, wheels, rotors, bearings and other parts. Our globally positioned facilities provide advanced manufacturing tools like CNC milling machines; advanced welding technologies like submerged arc, MIG and TIG. Full inspection and repair capabilities, including complete stripping and rebuilding of rotors, add to our services.
We can also store your spare compressors in our controlled climate facility, ready to go at a moment’s notice.
Dry Gas Seals
Many compressors still run with oil type seals at the shaft ends, like bushing seals or mechanical seals which leak and are inefficient.
Today, converting to dry gas seal technology is an industry best practice. There are significant advantages to convert to dry gas seals, even though oil‐type seals can still function properly at times. These advantages include very low gas leakages and losses, and an overall simpler system than a conventional oil system.
Feasibility studies on seal conversions are performed in order to identify the most economical solution for your compressor.
Restaging & Resizing
EthosEnergy Light Turbines has the technical capacity to study and design a project to return the compression to desired conditions.
This study service starts with a stage by stage study of the compressor curves under existing conditions. This enables EthosEnergy Light Turbines to provide calculated compressor curves and also provide the ERO production with the part definition for compressor staging. Detailed CFD calculations are carried out for each stage, the stage models are then developed step by step and validated for future use. This provides detailed information of the flow inside each impeller, as well as calculated loss coefficients for the performance programs.
In Houston, we have a full speed test facility for practically confirming the aerodynamic performance of the restaged unit prior to field installation.
