Sael and innovation: Platform ONE Drive Liquid Cooled
Fulfilling our mission voted to the “Spirit of Improving”, we applied the know-how achieved along the Tunnel Boring Machines technology experience, to our massive production drives. The working environment in which our inverters work in those heavy applications, are among the most severe that can be encountered: very small spaces, strong vibrations and high temperatures due to the fact that they are placed in the vicinity of the eight 400 Kw engines that carry out the rotation of the main drill, have driven our research and development team to create a water-cooled drive, extremely reliable, compact and strongly immune to thermal and mechanical shocks. Applied the drives in well-protected environments, such as the paper mill, it allowed us to be very confident and to encourage massively the paper mills to be led towards this technology.
Customer first and custom solutions is our philosophy: our mindset
The technological gap: fact based!
A recent equipment made for a paper mill, showed that our liquid cooled drives, practically without tangential fans (one each inverter), allowed us to remove all the ventilation normally mounted on every door of the electrical cabinet. The new electrical cabinets, where our panels are installed, previously mandatory and abundantly conditioned, today become normal rooms, since the system is independently cooled. The double-sided electrical panels, where the inverters are mounted, have closed air recirculation ensuring no contamination of dust, humidity and air acidity; they preserve over time, and in a perfect manner electronic, electromechanical and other various component. The experience gained on the subject by the Tunnel Boring Machines and the excellent performance monitored over the years due above all to energy saving, allowed the paper mill to save money every year, eliminating the need for maintenance of the air conditioners and fans. For this reason and for the significant reduction of the dimensions that the system has obtained, driven by the continuous research of innovation of the customer in the search for products and systems with high technology and energy saving, we have made the first WATER-COOLED plant in the paper mill sector. This specific Paper Machine Sectional Control Drive system dealts with the management of 46 AC motors of about 2 MW of installed power; the realization, unique in its kind and coordinated with our DCS in Drive, was strongly desired to equip the paper mill with all the qualities that our PLATFORM ONE offers today in the market. In April 2021, we started the third Paper Machine Sectional Control liquid cooled.
