‘Harmonic Filter’
An Engineeringtalk guide
Start with the news release
ABB drives reduce swimming pool energy bills from
ABB Automation Tech (Drives and Motors), which we summarised at the time by saying "ABB drives have helped a UK holiday park operator save GBP77,000 a year on energy bills for its swimming pools. ".
Several months prior to that,
we featured the news release CMOS digital photo IC for colour sensing from
Hamamatsu Photonics : "Hamamatsu Photonics has introduced a 12-bit digital output colour sensor photo IC. ".
In November 2009, we covered the news from Animatics
- take a look at OEMDynamics enhances linear belt drive
which says: "OEMDynamics, a division of Animatics, has announced enhanced features on the HLD 60-H3 actuator. ".
Take a look also at the news release from Ingersoll-Rand European Sales, PH30F diaphragm pumps transfer viscous fluids,
as well as Sullair unveils redesigned 200hp compressors from Sullair Europe,
and Fastpack drives cut energy use in fans and pumps from Micromech.
