New industrial air pumps for waste heat recovery

July 2017

Rotrex is participating in the H2020 EU project, DryFiciency, aiming to improve the energy efficiency in food drying by up to 80% by adding open loop waste heat recovery systems to existing food production plants. Heat pumps are well know applications in the food processing industry and can be used to ensure highly efficient and sustainable food production, including drying. Not only will the waste heat recovery system have a positive impact on our environment  with 57-73% CO2 reduction, but also a significant impact on the production costs because the recovery system reuses energy otherwise released into the atmosphere - the target is a reduced production cost by 20%/kg!

To ensure maximum energy improvements, high pressure ratio is required hence  centrifugal compressor technology is the ideal solution due to superior aerodynamic efficiencies, which is where Rotrex is contributing to the DryFiciency project. Within the project, Rotrex is developing a new type centrifugal steam/vapor turbo-compressor design, fully integrated with a 105/175kW high speed electric designed specifically for industrial use. With the technology and IP from Rotrex it will be possible to apply energy and cost efficient mechanical vapor recompression for steam based thermal processes. Rotrex aims to be ready for turbo-compressor implementation in 2018.    

The new innovative design reinvents how industrial steam/vapor turbo-compressor work and offers unique special features such as:

  • Highly efficient steam compression (up to 75% aerodynamic)
  • Integrated lubrication system (food grade)
  • Impeller speed up to 90.000 rpm
  • High pressure (PR > 6)
  • Extremely low cost  maintenance - minimal system downtime <1h
  • Low cost investment - ROI less than 2 years!

Rotrex C8 released

January 2011

Rotrex is proud to announce the release of the latest breakthrough for the patented Rotrex traction drive technology, the Rotrex C8.

The C8, which has been developed especially for extremely compact applications, features a traction drive with an outer diameter of 91 mm (19 percent less than the already very compact Rotrex C15).

The Rotrex C8 features the well known whisper silent traction drive type as the other members of the Rotrex C family, but in an even further simplified design and will thus be even more economic than our larger superchargers.

This makes the C8 ideal for applications such as smaller fuel cells, subcompact cars, unmanned aircraft and small displacement motorcycles. The C8 has been released with a 240,000 rpm red line, a max air flow rate of 0.065 kg/s and as such can provide sufficient air for applications up to approximately 80 hp, depending on the actual application.

After an extended period of meticulous development Rotrex can now offer our clients the granddaddy of the C38 range: The C38-91.

December 2010

Targeted specifically at those clients that want to enjoy the refinement and sheer acceleration of a Rotrex application but need that extra grunt and sheer power, the C38-91 features the best efficiency of the C38 range and flows 11% more than the C38-81.

Even at the very upper end of the power band, at a verified flow rate of 0.63 kg/s where no Rotrex has ever gone before, the measured efficiency of the Rotrex C38-91 is 65%, making sure your high power application will not unduly load your engine with thermal strain.

The C38-91, which shares the same basic drive dimensions and features a compressor housing only 8 mm longer (axial dimension) than that of the other members of the C38 family, serves up a peak (isentropic) efficiency above 75% and has a wide high efficiency island, guaranteeing forceful acceleration all through the engine rev range, as well as great gas mileage when you are not 'on the throttle'.

Novel supercharger strategy allows gasoline to compete with diesel powertrains.

September 2010

Unique variable-speed drive by Rotrak improves supercharger efficiency. Rotrak will present a uniquely efficient supercharger system in a paper at the 15th Supercharging Conference in Dresden on September 24.

Power Enterprise does it again!

January 2010

For the second year in a row, the Japanese distributor of Rotrex, Power Enterprise, has won a prestigious award at the Tokyo Auto Salon.

While last years award was received for the high tech high power quad charged dual Rotrex C30 Nissan GT-R, this year the award for best product in the Eco department was received for Power's Rotrex charged Honda Insight hybrid, running on LPG gas.

The kit of Power Enterprise demonstrates that respect for the environment does not have to come at the expense of driving pleasure: The stock 88 hp of the 1.3 liter engine is, by the application of the Rotrex C15-16, spinning at up to 142,000, increased to 130 hp, applying only 0.4 bar of boost.

Another true testimony to the efficiency of the Rotrex and the engineering prowess of Power Enterprise!

Power Enterprise wins the "Best Modified Car of the Year" award at the 2009 Tokyo Auto Salon

January 2009

In an impressive display of technical savvy and inventiveness, Power Enterprise, the Japanese distributor of Rotrex superchargers, successfully demonstrated its engineering capabilities at the 2009 Tokyo Auto Salon, taking on and beating all other designs by being awarded the "Best Modified Car of the Year" award with their quad charged Nissan R35GTR, featuring twin Rotrex C30-94 units.
The target of Power Enterprise with this project, which is scheduled for general release by May 2009, was extreme but well controllable torque over a broad power band, making the already fearsome GTR a thoroughly frightening track weapon: More power and torque would, through the application of turbo chargers, either have led to increased turbo lag (twin large turbos) or much higher thermal load (quad turbos).

Not so with this setup, in which the twin OEM turbo's pre-compress the air going into the twin Rotrex C30-94's that in turn, through reduction of the work load as seen by the turbo chargers, remove any turbo lag and complement the turbo's over the entire power band, creating a staggering torque curve available with near- instantaneous response.
