and they include a differencial pressure gauge . This latter allows the direct control of the obstruction degree of the filter and it allows the cleaning process only when and where it is necessary. This intelligent device is able to recognise the outputs in which a load is applied , thus it can command automatically and directly only the exits effectively used. This device can be supplied in different models and it can control from a min. of 2 to a max. of 96 electrovalves, thus it can be used both in small and in big dimensions plants. On demand, it is possible to applied to the Ecomatic expansion modules in order to guarantee the control of more than 96 electrovalves, thus being used in bigger dimensions plants .
The Serial Solutions represent the optimal system for medium and big dimensions plants. These tools permit to reduce or eliminate almost completely the costs of the connections of the valves to the control and command device. These solutions exploit the economisers ECOSERIAL jointed with the serial pilot box RPB which can be assembled on our integrated or traditional tanks. The Ecoserial device is a digital economiser with differencial pressure gauge able
to pilot til 204 valves by connecting itself to a pneumatic driving module RPB with only two threads. The Ecoserial 2 has the capacity to menage the cells of filters on serial modality both in on-line modality and in off-line modality, guaranteeing the best control of the most complex plants. This system can receive the cabled tank, ready for use. Thus, it allows to avoid the onerous costs of connection, ensuring a considerable spare in terms of installation time by the final customer. These devices RPB are available on ATEX version (zone 21,22), following the European directive 94/9/EC. Owning these features, these devices can be used in environments in which potential explosive atmospheres might manifest themselves.
