About Rotrex
ROTREX was formed in 1990 and became a member of the A.P Moller Group in 2000. The A.P. Moller group is the largest Danish group of companies.

Up till 1997 the company developed the ROTREX supercharger and sold it as prototypes for Original Equipment development in limited numbers to gain experience on functionality, reliability and to ease the product improvement process.

Since 1997, ROTREX has participated in the development of OEM supercharger applications and grown its aftermarket supercharger business organically.

In year 2003, a new structure is taking place for the aftermarket distribution of superchargers, whereby ROTREX superchargers are made available through the worlds leading performance companies.

In 2004 the company expanded its operations into a new headquarter facility in the Copenhagen area of "Herlev". The new facility enabled expansion opportunities for both manufacturing and development activities, closely related to growth in sales and participation in new OEM supercharger projects with significant volume potentials.
================================================
The Combine Rotrex/Antonov AMM dual speed supercharger set unit reduce the CO2 emissions.

Downsizing of an internal combustion engine is an effective way of meeting future emission's standards. Downsizing entails reducing the volumetric capacity of the gasoline or diesel engine. However, reductions in volumetric capacity directly affect engine performance and drivability of the vehicle. Forced induction systems are generally acknowledged as a leading technology enabling the retention, or enhancement, of performance whilst gaining the emission and fuel economy benefits associated with downsizing.

For diesel or gasoline downsized engine applications, the Rotrex supercharger in combination with a variable drive or electric motor can be applied alone or with a larger wastegate turbocharger. This improves transient response, fuel economy, reliability and is cost competitive compared to advanced turbo systems.

With future improvements in combustion technology lowering drive cycle emissions, emphasis will be focused toward cold start as a major contributor to overall tailpipe emissions. Since catalytic performance is influenced by temperature, then catalytic light-up is a crucial phase within engine emissions performance. The Rotrex boosting unit has a distinct advantage in this area. Since the Rotrex unit is directly driven, it in no way inhibits the flow of exhaust gas heat to the catalyst, so achieving improved emission levels.

Currently Rotrex is engaged in several downsizing projects combining Rotrex superchargers with step-up, CVT and turbo technology. (= Antonov).

Rotrex superchargers are designed to reflect the 10 year lifetime requirement of an automotive component. A standard range of superchargers is available to match a broad range of applications.

Also, the Rotrex supercharger has been easily customized for client applications optimizing integration, performance and cost.

Key design features for OEM market applications are:

Reliability - rolling elements with patented ramp effect preventing excessive stress

Low NVH - no gears. Planet rollers give silent operation and less vibration

Reduced emissions - no heat inertia impact on exhaust gas reducing catalyst light up time. Application with downsized engines reduces fuel consumption and CO2

Cost - standardized components and a simplified assembly process makes it turbocharger competitive

Manufacturing - high volume compatible processes

Installation flexibility - the compact traction drive based supercharger is independent from the engine exhaust simplifying installation and packaging.
