RECOVAR®-E

RECOVAR®-E is a highly reliable, variable-speed gearbox with an energy recovery system and maximum efficiency across all operating points. A state-of-the-art system consisting of mechanical and electrical features, it offers an ideal solution of both worlds.

Maximized uptime and process security to ensure sustainable operation
Broadest flexibility to support various process and industries
Highest Efficiency to increase profit and lower emissions
Smart design to simplify installation and servicing at point of operation

RECOVAR®-E stands for RENK ECOnomic VARiator. From an operator perspective it means highest productivity in the oil and gas, chemical, hydrogen and many other process industries.

Features

Drivetrain efficiency 95% – Best in class for variable speed solutions
Maximum availability – Mean time between critical failure is over 30 years
On-site maintenance – Spare part exchange possible on-site: gear rotor set, bearings, SI motor
Low inertia – Allows for easy direct on-line starting of motor
Low total harmonic grid distortion – Ideal for local grids
Unparalleled simplicity – Engineered for maximum modularity
Water or oil cooling – SI motor cooling is adapted to site requirements
Smaller footprint – Same output while taking up much less space in the electrical room
Less weight – than a full-power FC and transformer
Less heat load – in the electrical room
