Howden is a world-leading turbomachinery manufacturer with over 300 years’ of combined experience across its legacy brands of TURBLEX, HV-TURBO, Spencer and Donkin. Howden products are designed to achieve maximum efficiency and long reliable operational life through the company’s focus on engineering excellence.

Howden now introduces its high-speed centrifugal compressor with permanent magnetic bearing motor and Dual Point Control with a control system that adjusts the VDV continuously in order to optimize the conversion from velocity (dynamic pressure) to useful pressure (static pressure).

The aeration requirement is similar to the variation of the daily water cycle. The need for oxygen given by the compressed air needs to adapt to the level of effluent water coming in. Dual Point Control enables a turn down from 100% to 35%. Most other high-speed compressors on the market using single point control are limited to overdesign or a turn down to 60% maximum.  The turn down from 100% to 35% enables a wider area of efficiency and turn down running at design pressure. This means higher efficiency from 100% to 60% and no wasted air from 60% to 35% turn down giving further savings on energy usage.

The Howden high-speed compressor utilizes the legacy Turblex centrifugal compressor with over 1,600 blowers in more than 500 installations in the U.S. alone.  

Howden Turbo is a complete blower package in a single enclosure with plug-and-play concept. The unit can be placed as a stand-alone unit in a new site or also be ducted into an existing filtration system. All Howden Turbo blowers are fully equipped with Howden Uptime and provide an invaluable insight into the performance of the equipment, offering blower and plant optimization opportunities.
