Technology - Concept

Key to the Rotrex supercharger's unique compactness, efficiency, low noise and reliability is its state of the attraction drive technology.
Great speeds and low noise are just some of the advantages of traction drives over traditional gear transmissions.Traction drives transmit power through friction forces between its rolling elements.
Advantages of the patented traction drive design are:

> Torque-on-demand
> Speed up to 250,000 rpm
> Efficiency up to 98 percent
> Compactness
> Reliability
> Low NVH
> Low cost

Design & Production 

The traction technology inside every Rotrex supercharger

demands extremely accurate components and assembly.

The manufacturing of our superchargers is therefore highly

developed, involving efficient quality control and supply

chain management.

The Rotrex patented traction drive uses an elastic annulus with a small pre-span to secure contact between the roller planets and the sun shaft with a reasonable force. The patented "ramp effect" increases efficiency and reliability in the transmission by regulating the torque transfer capability on demand through self-adjusting planet geometry.

To enhance performance, the Rotrex traction drive uses a special traction fluid. These fluids are a new family of synthetic hydrocarbon oils and greases offering a series of unique performance advantages. Developed specially for its use in Rotrex superchargers, the SX100 momentarily increases viscosity under high surface pressure,enhancing the traction drive performance by securing the optimum friction between rolling elements while cooling and protecting the system.

This traction drive combined with the latest technology in centrifugal compression, characterized by high adiabatic efficiency and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution.

After Market Supercharger Data

Rotrex superchargers are the latest in forced induction systems offering high efficiency, compactness, reliability and silent operation. The C range consists of the C15, C30 and C38 families.

The unique small size of the C15 makes it the most compact supercharger on the market. The C30 and C38 cover the market all the way up to the large displacement American muscle cars.

The installation guide contains general information on how to choose a supercharger for a particular application and other instructions to help you get the best out of your Rotrex.
