The industry has been developing solutions for variable speed settings for compressors and pumps for over 20 years now. Prior solutions did not prove effective over the long-term due to their complexity as well as high power losses and extreme maintenance costs. Higher efficiency requirements paired with the lowest possible investment and long-term operation form the basis for our new concept:

RECOVAR®-E is a variable-speed power splitting gear unit with an energy recovery system and maximum efficiency across all operating points. RECOVAR®-E stands for Renk ECOnomic VARiator. A modern hybrid consisting of mechanical and electrical features that offers an ideal solution for both worlds.

More than 50% of all compressor and pump systems over 3 MW require a variable-speed drive. RECOVAR-E offers an optimal cost-effective and efficient solution for applications of this type.

Power: 3 – 150 MW
Low speed shaft: < 1 800 rpm High speed shaft:4 000 - 25 000 rpm Ratio:3 - 15 Efficiency:97.80%
