RECOVAR®-E stands for RENK ECOnomic VARiator and is RENK’s variable-speed gearbox, which impresses with exceptional reliability, maximum efficiency at all operating points, and energy recovery under partial load.

Application areas for RECOVAR®-E include variable-speed pump and compressor applications in the oil and gas industry, petrochemicals, chemicals, hydrogen production, and other process industries. The RECOVAR®-E offers high flexibility with gear ratios from 3 to 15, a variable speed range from 70 to 105% at constant input speed, power transmission up to 150 MW and an efficiency of approx. 97%.

The system combines proven mechanical technology with state-of-the-art, industry-grade SI drives and electronics. Thanks to the extensive experience of our engineers and production capabilities, RECOVAR-E offers customers the best of both worlds:

• Maximum availability, thanks to the back-up functionality of the fixed-ratio mode
• Highest efficiency through the use of slide bearings and a power-split mechanism, leading to increased profits and reduced emissions
• Intelligent, simple design to ease on-site installation and maintenance
• Small footprint, making it the preferred choice for offshore applications
