Repairing an existing Turboexpander for which little or no engineering documentation is available poses no problem for O.C. Turboexpanders. Our dedicated shop personnel can quickly document the dimensions of existing components and then handoff details to the engineering department for design checks and, in turn, precise engineering drawings. From simple one-piece components to intricate, multilayered assemblies, O.C. Turboexpanders can quickly reproduce vintage turboexpander components, assured to properly fit and provide years of reliable service.

The heart of the Turboexpander/Compressor is the wheel itself. O.C. Turboexpanders’ ability to flawlessly reproduce hub and shroud contours from old parts and precisely matching the mating, casing contours guarantees maximum efficiency from an existing machine.

Intricate blade surfaces are captured with a laser scanner. From point cloud data, a blade surface model is refined. The surface model is solidified and patterned on the hub, finally translating the raw data into a solid model. Mass and center-of-gravity parameters are then able to be precisely calculated, thereby validating the rotordynamic model.
