The Rotrex C15 is an extremely compact centrifugal supercharger. Rotrex C15 is a range of centrifugal superchargers for large variety of applications where the compactness is one of the key issues.
 
Countless number of small applications can now be boosted by this very efficient and silent unit which supplies air flow up to 0.22 kg/s. Through the patented hi-speed planetary traction drive, the C15 achieves impeller speeds of up to 201,500 rpm.
 
The exceptional high speeds of the drive give an unsurpassed power to size ratio compared to any other supercharger on the market. The very low noise and vibration characteristic as well as the high efficiency of these superchargers set the industry standard for what is achievable.
 
The C15 range of superchargers is designed for four stroke gasoline engines. However two stroke engines or even diesel engines can benefit from these superchargers with remarkable results.
 
Depending on the application the C15 will support engine outputs up to 175kW. The C15 can also supply clean pressurized air for other applications such as exhaust gas aftertreatment systems, agriculture applications, fuel cell power plants etc. The groundbreaking compact size enables a very flexible supercharger installation particularly on engine applications where optimum efficiency as well as weight and size are essential.
 
The supercharger features an integrated dual-action oil pump that works as a dry sump scavenging pump in addition to being the oil supply pump.
 
The self-contained oil system allows flexible positioning of the supercharger on the vehicle and has the benefit of fitting the supercharger without worrying about tampering with the oil system of the engine or any other accessory. The Rotrex C-type supercharger has been developed and extensively tested with the special Rotrex traction fluid.
 
To maintain the ultimate level of performance and durability it is very important that the unit is exclusively run with special Rotrex traction fluid. Make sure the inlet oil temperature is within the range specified in the table on the next page. Any deviation from the standard Rotrex oil circuit requires approval from Rotrex.
 
Acceleration and power delivery
Compared to traditional centrifugal superchargers, the Rotrex unit offers the highest boost at low and mid-range engine speeds. Compressor speeds as high as 240,000 rpm results in superior acceleration and power delivery.
 
Reliability and low Noise
The secret behind Rotrex’s low noise level is the high-tech patented Rotrex rotary drive system. Smooth planet rollers without teeth’s gives silent operation, less vibrations and offer reliability under all types of operations.
 
Compact
The compactness and shape of the small Rotrex superchargers offers unique packaging advantages and installation flexibility, an important characteristic in the small modern engine compartment.
