Past and present

1932: Turin. “Società Idrotermica Razionale Industrie Affini S.I.R.I.A. spa” is founded. The company manufactures and installs heating and cooling systems and large thermal plants for buildings. 1933: S.I.R.I.A. S.p.A. becomes a member of the Industrial Union of Turin and of AMMA “Association of Metal and Mechanical Industries” to which it is still associated today. After WWII the company activity is wider and focalizes on the water and plant sectors and ends up offering turnkey systems in the 60’s. 1970: thanks to the favourable geographical position of the production plant at Brusasco, at the crossroads of the provinces of Torino, Asti and Alessandria, the production development can finally focalize on the main North Italian water utilities. 1980: the Ferrero Family purchases the Company and changes its name into Nova Siria S.r.l. The new site for the company is Bibiana, at the mouth of the Pellice Valley. 2006: two new plants are acquired at Roletto, a town between Pinerolo and Torino. The new facilities include areas dedicated to production and specific tests, with lifting equipment suitable for handling large-sized parts. During 2006, the Italian sales network is completely re-organised through activation of new Agencies, in particular in the South of Italy. In 2006 a new company, CF Rappresentanze Industriali snc, is added to the Nova Siria as commercial partner for management of the Italian sales network alongside the Agencies and in synergy with Nova Siria Italian sales management. 2009:  with the the setting up of CF International srl. which is aimed at the Multiutilities, construction and maintenance companies of water-gas distribution networks, retailers and engineers. The company soon becomes the reference point for a wide range of high quality products and solutions which are complementary to Nova Siria product range. CF International closed in 2014 and its products are now promote and sell by Nova Siria throught the C.F. Line. 2009 – 2014: important investments to speed up the internationalization process, through the participation in various Internati onal Exhibitons of the sector and the activation of new distributors in all the continents. 2015: Nova Siria became part of the Austrian group Hawle, one of the international leaders in quality and innovation of valves and pipe connection. Aldo Ferrero, surveyor, born in 1925, after a thirty-year experience accused as a plant manager in several important mechanical companies in Turin area, founded Nova Siria in 1979 together with his sons Luigi and Mario. Technical supervisor of the company, he deals with R&D and new manufacturing process technologies. During the Nineties ha was named “Knight of the Italian Republic” and in 2013 he received the “Loyality Award to Work and Economic Progress” issued by the Chamber of Commerce of Turin. In 2020 another significant step has been taken in the NOVA SIRIA continuity project, initiated by its founder, land surveyor Aldo Ferrero in the 80s. After being run for almost 40 years by the second generation, with his sons Luigi and Mario, as of January 2020, the baton has passed to Marco Ferrero (now Managing Director) and Francesco Ferrero (now Managing Director), sons of Luigi and Mario respectively and representatives of the third generation. A generational handover in full compliance with continuity of values, aimed at preserving the principles of excellence, quality, and social responsibility which have been the pillars of Nova Siria since the year it was set up. These values continue to be important also after the entry of Nova Siria in the Hawle Austria Group in 2015. Marco and Francesco Ferrero have grown professionally in the company, alongside founder Aldo Ferrero and, in recent years, their respective fathers, Luigi and Mario, carrying on traditional values and combining them with increasing dynamism. Alongside Marco and Francesco, an operational role is played by Stefania and Ilaria, the first daughter of Luigi and the second of Mario, who deal respectively with marketing, communication and export, within the company:“Our grandfather, Aldo, and our fathers, Luigi and Mario, taught us that work, if based on competence and quality, can promote both personal development as well as progress and well-being for all employees and collaborators,” stated the Ferrero cousins in unison. Luigi and Mario Ferrero’s presence in the company as consultants is a further cornerstone, thus guaranteeing the continuity of the company and the commitment towards its employees, collaborators, customers and suppliers.


The mission of Nova Siria is continuous growth, creating value through quality products that ensure maximum customer satisfaction. Growth is rooted in the absolute respect of relationships of trust and collaboration with employees and suppliers, through the commitment to a safe and healthy work environment and compliance with laws and labor contracts.


Topics whose care is considered fundamental for one’s business, the continuous improvement of these two areas is considered a success factor. The certifications represent the recognition of the company’s commitment and willingness to pursue an all -round improvement policy for quality and environment, which involves all company structures. Since 1998 the company has adopted the UNI EN ISO 9002 Quality Management System. The company has implemented the Quality Management System making it compliant with the new ISO 9001 – 2015 standards.


In 2023 Nova Siria is delighted to announce that it has been granted ISO 14001 – “Environmental Management System Certification” by TUV Italia srl.
The achievement of this certification is a strategic choice made by the management of Nova Siria and Hawle with the planned goal of creating integrated quality, safety and environmental management systems in the medium term.
This strategy has the benefit of helping the company to not only be effective, but also productive, by using integrated tools that allow the company’s processes to be kept under control.
A synergically conducted process analysis allows the identification of new strategic approaches that jointly evaluate environmental impacts, process and product quality improvement, and the reduction of risks for workers.

Nova Siria S.r.l.

The CEO – Francesco Ferrero


Nova Siria uses design systems with “solid modeling 3D” (Solidworks® – Dassault Systemes) techniques. They allow the management of specific structural calculations of “Stress Analysis” relative to materials resistance, external and internal stresses such as loads and pressures, through simulation of mechanical and hydraulic stresses in operating conditions. Design rules provide the maximum quality grade for each component, which is achieved through the use of materials which comply with National and International standards.


The design stage and 3D simulation is followed by a check of technical performance characteristics and actual in-house testing of prototypes.  In order to always assure the best reliability of production, Nova Siria can perform the hydraulic seal tests under mechanical stresses according to the International standards or, upon request, according to the specific requests of the Customer.

Research & Development

Nova Siria makes considerable investments in the analysis of new product technologies and is available to examine any request of the Customer which find the application in their operation areas, performing feasibility studies and overseeing the design process and experimentation.
