The Vorecon with Dual Torque Converter (photo) is a variable-speed planetary gear with two matched torque converters. It delivers high efficiency, even into the lower speed range, providing an efficient way to control the speed of large pumps and compressors in a variety of fields. It is up to 2% more efficient than variable frequency drives (VFDs), says the company. The patented Vorecon with Dual Torque Converter is expanding its footprint in the U.S. market, with five Vorecons equipped in compressor stations transporting natural gas from the Marcellus shale formation into markets in the mid-Atlantic and Southeast states. These Vorecons are increasing transport capacity by over 25%, and improving reliability and efficiency in the process, says the manufacturer. — Voith Turbo GmbH & Co. KG, Heidenheim, Germany
