Basically, if the height of the building made filter change possible a Top Removal System was chosen, as such systems always have a lower residual dust content compared to Side Removal Systems. However, if the building was too low, then a Side Removal System was always chosen, although these always meant longer stoppages for changing filter hoses and cleaning. This was seen as the lesser evil compared to the high costs required for modification work to the production facilities.
This dilemma inspired the design engineers at NETZSCH Trockenmahltechnik GmbH to look at the problem of filter hose changing from the customer´s point of view. The resulting worldwide innovation, SmartRemoval, was presented for the first time at this year´s POWTECH in Nuremberg, Germany and aroused considerable interest in the branch. This new type of filter hose changing system combines the advantages of conventional Top- und Side Removal Systems in one product.
The main conceptual emphasis during the development of the SmartRemoval was first and foremost on enabling an intuitive filter hose change without tools, which could be carried out easily and rapidly. In practice stoppages necessary for changing the filter hoses constitute a major cost factor, which can even be decisive for the profitability of individual campaigns with frequent product change.
A further focus was on reducing the residual dust content down to that of a Top Removal System. In the end, the designers of the SmartRemoval were able to solve both tasks. The well thought out installation technology (patent pending) is constructed in such a way to exclude mounting errors and the mounting of the SmartRemoval is up to 80% quicker than that of previous Side Removal systems. In addition to this its residual dust content is so low that it is comparable to that of conventional Top Removal systems.
In future users and plant builders of dust filter systems no longer only have the limited choice between two systems characterized by obvious weaknesses. On the contrary, now everybody can choose the new optimal solution when building, modifying or modernizing their plant regardless of the height of the building and without having to tolerate high residual dust contents: NETZSCH SmartRemoval.
