‘Harmonic Filters’
An Engineeringtalk guide
Start with the news release
Riley to distribute pressure-fed shot blasting from
Riley Industries, which we summarised at the time by saying "Riley Surface World has announced an agreement with Contracor to distribute its range of pressure-fed shot blasting systems in the UK. ".
Several months prior to that,
we featured the news release Bambi introduces silent oil-free compressor range from
Bambi Air Compressors: "Bambi has launched the silent HT oil-free compressor range.".
In November 2009, we covered the news from Exide Technologies
- take a look at JTT uses Exide gel batteries and SP chargers
which says: "JTT Equipment Services of Grantham is using Exide Technologies' maintenance-free Sonnenschein monobloc gel batteries and high-frequency SP chargers. ".
Take a look also at the news release from Ingersoll-Rand European Sales, Ingersoll Rand introduces desiccant dryers,
as well as Fastpack drives cut energy use in fans and pumps from Micromech,
and Carlo Gavazzi launches RSBT-type 15kW soft starter from Carlo Gavazzi.
