The turning point came ten years ago, when Sts Isolamenti – a company from Turin founded in 1978 and specialized in noise control solutions – filed its first patent and accelerated its transformation path, increasingly focused on research and development, under the leadership of Giorgio Cellerino, the founder’s son, who has been heading the family business since 2012.

Focus on research and development
Today the small Piedmontese company (about 2.5 million euros in turnover in 2025 and 20 employees) already holds four patents and has been recognized as an innovative SME, one of the few in its sector in Italy. “Over the years we have developed skills especially in the so-called HVAC sector, that is ventilation, air conditioning and heating systems, which remain our core business,” explains Cellerino. “But in the last two years we have developed some very innovative products, thanks to a crowdfunding campaign that involved as many as 60 investors, which also opened the doors to a rapidly growing market, that of Data Centers.”
Much noise for Data Centers
Few people know, in fact, that among the environmental issues related to these huge servers – essential to support the spread of Artificial Intelligence, 5G and Edge Computing – there are not only the high consumption of energy and water to operate and be cooled, but also the continuous noise they produce. So much so that in some US states, including New York and Virginia, there have been numerous protests against their construction and many projects have been blocked or delayed for this reason.

Well, Sts is able to provide solutions to this problem, thanks to a patented technology that makes it particularly competitive in a sector where the systems adopted are still quite outdated and not entirely suitable for the new reality. “We provide soundproof enclosures that, placed outside these machines, allow them to work as before, but reducing the noise and, at the same time, protecting them from the weather and thus ensuring greater durability,” explains the entrepreneur.
Growth prospects
In 2025 alone, the company recorded an increase in soundproofing requests for Data Centers of more than ten times compared to previous years, and the growth prospects are very encouraging: “Last year we achieved 2.5 million euros in turnover, this year we reached the same figure already in July and we expect to sextuple revenues by 2027.” Sts has recently completed a supply for a Data Center in Lazio and is finishing an order in Frankfurt: “But we have many projects underway, with open tenders that together reach a value of about 60 million euros,” concludes Cellerino.
