Intended for use with centrifugal compressors. Mounted close to the inlet, provides unregulated or variable pre-swirl at the compressor inlet.
features
Provides the facility to modulate flow pre-whirl ahead of the compressor
Enhances compressor surge limit or enhances flow range
Supports delivery of increased low speed torque and improved transient response
Low cost device
technology
The switchable device has a simple butterfly valve which can be varied in angle to vary the proportion of flow passing through a whirl inducing concentric passage
CFD analysis has been used to optimise the package and geometry
Testing on bench and on engines has confirmed the benefits are achievable
Up to 30% torque increase achieved at the critical low engine speed region.
applications
Gasoline and Diesel turbocharged engines
Passenger car and heavy duty engines
Application and design support available from IP
Rapid prototype parts can be supplied to suit your specific package
