RECOVAR®-E: The variable speed drive system
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 gearbox 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.
