KEB’s technology expertise enabled the creation of Energy Recovery Systems (ERS). These are electronic systems that control turbomachinery and convert energy from sources like geothermal, air separation, or waste heat recovery. The recovered energy is converted to electrical power that can be used by the building facility or put back onto the mains.
Energy Automation Solutions
High Speed Drives
KEB has earned a reputation for controlling high-speed motors and generators - the exact technology used in turbomachinery. Innovative power technology is offered across a full power range. Of course, all drives carry the necessary agency approvals like UL.
Sensorless Closed Loop™ (SCL) Technology
KEB’s SCL algorithm provides better speed and torque regulation than commonly used V/Hz control. Another advantage is that SCL does not require encoder feedback – this is difficult to achieve at high speeds.
Innovative, Efficient Energy Solutions
KEB Energy Recovery Systems leverage a unique combination of innovative technologies, including grid protection relays and custom-designed filters, to safely convert high-frequency electrical power into usable energy for building power or utility. Typical processes for KEB’s ERS include air separation, geothermal, and waste heat recovery.
Customers choose KEB for compact, dependable Energy Recovery Systems that streamline control and workflows for process operators. Our solutions are designed for fast, easy, and safe integration into your existing energy process or system. KEB load drives also regulate generator speeds automatically, eliminating the need to manage the flow and pressure of process gas.
High-Speed Motor/Generator Applications
KEB Energy Recovery Systems are tailor-built for the demands of high-speed motor and generator applications. Advantages of these high-speed solutions include compact size, high power density, and extreme process efficiency. KEB drives can output frequencies up to 1600Hz, making them ideal for running high-speed generators and motors.
Alongside output frequency and hardware advantages, KEB’s SCL™ (Sensorless Closed Loop) algorithm eliminates significant cost and noise issues by removing encoder feedback in high-speed applications. SCL-optimized generators minimize rotor heating while bolstering energy output, which benefits both the user and machine manufacturer.
The Future in Energy Recovery Technology
KEB supports machine builders across the world with powerful technologies for energy recovery. Our ERS and SCL solutions offer unmatched performance and flexibility, allowing KEB systems to work with a huge variety of generator types and designs. We prioritize efficiency and motor heating reduction to optimize results across high-performance systems.
