FONCTIONNEMENT
The EMC patent
When compared to other systems, the sum of all its advantages makes EMC filter technology the industry standard. EMC combines the advantages of online and offline cleaning.
Offline cleaning offers two decisive advantages over online cleaning systems: a significantly lower filter differential pressure and an increased bag service life as a result of the gentle cleaning of the filter bags in a no-flow state.
Disadvantageous, however, are strong fluctuations in the filter differential pressure due to periodic changes in the active filter area resulting from the opening and closing of the shut-off devices for the filter chambers and/or individual modules.
In online operating mode, however, the filter differential pressure is stable because of the uniform filter area, albeit at a higher level. Because maintaining a constant filter differential pressure is an important prerequisite with process filters in order to avoid negative effects on the overall process and product quality, offline and semi-offline filters cannot be used or can be used only in a limited way.
Only with patented EMC technology is it possible, and this as a result of the system’s mirror-image control of the shut-off devices of individual modules, to maintain a constant active filter area and thus a stable filter differential pressure.
