The compressor is a complex product, where multiple components come into play. But among these it is undoubtedly the inverter that has the most important task: it is in fact used to modulate the speed of the compressor as needed to maintain the pressure value at the desired level. This guarantees a remarkable energy saving for the user, avoiding having to switch the machine on and off too frequently.
The importance of this component has led Mattei to form a partnership with one of the major international players in the industry, Mitsubishi Electric, the Japanese multinational that makes
quality, reliability, continuous innovation and maximum customisation of products its key strong points. And,results in hand, this partnership has proven to be a winning decision over time
"We came from an experience that had presented some criticalities- explains the Director of Operations at Mattei - and we were therefore looking for a partner who could combine
efficiency, cost and reliability. Our encounter with Mitsubishi Electric proved to be exceptionally interesting from the very first approaches. We were able to immediately appreciate the enormous
affability of this company, whose managers travelled over from Japan to get to know us personally and investigate the characteristics of the products we needed".
In fact - says Marco Bertani, commercial director Mitsubishi Electric- Mattei was among the prospective companies that we were looking at, despite the fact that, given the central role of the inverter in the compressor, changes are not that simple. And yet, when put to the test, we made it". It was, however, no easy task: "It consisted in - continues Bertani - customising the inverter for Mattei, with a function that allowed constant monitoring of the temperature inside our power modules, so as to intervene in case of any alert signals. Over the years, in fact, our inverter has always demonstrated absolute reliability and quality. And now, in the new inverter which Mattei will install on its new Blade that will be presented in Hanover, a similar feature is already included as a standard feature".
The reliability of the Mitsubishi Electric inverter is one of the features that Mattei has most appreciated, together with the efficiency of its support network, which covers all parts of the world: In fact, in four years we have never encountered any problems," comments Del Grossi with a certain satisfaction The secret lies in the philosophy of Mitsubishi Electric: "Thanks to the high reliability of our products, based on 200 functional tests conducted on every piece, all our customers can focus their efforts solely and exclusively on the development of the machines".
But Mitsubishi Electric is also innovation. And the new inverter which will be installed from the end of the year on all Mattei compressors has some important new features. First, the possibility to connect it to a USB port to download the parameters and constantly monitor the status of the inverter. So new "alert" features which will indicate to the operator the ordinary maintenance to be performed. Finally new energy saving functions which will allow, under certain conditions, to reach a level of savings of 5-10%.
