The economist model “MCS” uses advanced microprocessor technology, expressly designed to control the interval and the pulse time of diaphragm valves using the DP and focusing on reverse pulse-jet systems with pneumatic cleaning procedures. All the technical characteristics satisfy the “CE” Directives which relate to isolation and low voltage power. The unit has been tested by an authorized institute and is in conformity with the European Regulation 89/336 EEC and 93/68 EEC.
The MCS is available with a minimum of 4 outlets(MCS$) up to a maximum of 128 outlets(MCS128).The intermediate models increment in multiples of 4 (MCS4, MCS8, MCS12 etc.).
The principle of the MCS is as follows: an internal sensor registers the progress of the DP in the filter and when it exceeds the value of the set DP in the filter and when it exceeds the value of the set DP, The unit automatically sends a signal to the diaphragm valves in sequence(skipping the outlets which are not connected or where there is no charge recognized). The unit also allows you to set the MANUAL CYCLE TIME(this is the time it takes for all the valves to complete an entire cleaning cycle). This way you obtain the automatic regulation of the Pause Time between one valve and the next. All this is possible thanks to a sophisticated algorithym, which is able to automatically optimize the Pause Time, starting from the set Manual Cycle Time. On the digital display of the unit, you are able to identify all the operation values, such as the set DP, DP Alarm, Pause Time, Hour Counter, No. of cycles for Shut Down Cleaning and the relative Pause Time.
The Economist also has the PRECOATING function, which subordinates the start of the cleaning cycle until such time that a preset DP Value for PRECOATING has been reached(this DP Value has be greater than the set DP).
This allows the filtering elements to overload with reagents and preparation powders. It is possible to set an independent value for the DP Alarm as well.
Model 200DP is offered with Goyen Label.
