Teseo piping delivers for Persico Spa

21 August, 2015

Teseo was selected by Bergamo-based Persico Spa to supply the compressed air distribution system in the Nembro factory. The compressed air system, comprising several kilometers of HBS piping, was designed to meet the strictest energy efficiency standards.

Teseo has supplied its HBS modular piping to build a new compressed air distribution system in the factory of Persico Spa, a Bergamo-based company primarily engaged in the automotive, industrial and marine industries.

Founded in 1976, Persico Spa provides co-design, engineering, prototyping and modeling services, combined with automation systems, with a role of global player in the target industries. Based in Nembro, near Bergamo, the company also has production and sales units in Germany, China and the US.

Within the project for the refurbishment of the ex-Comital industrial site, covering 18,000 sq m, the existing manufacturing structures have been expanded with new business divisions. Until recently, the different units were fully independent, each with a 30-50 kW compressor, while today a compressor room with 3 inverter compressors (including a backup machine) with 75, 55 and 37 kW rating, supports a central distribution backbone. This approach has lowered consumption significantly and has resulted into an estimated 30 per cent cost saving.

Challenging task

Due to demand peaks and discontinues operations in the different units, the design and optimisation of compressed air systems was very challenging. For this reason, Persico Spa relied on the qualified consulting of CGC, a company in the Bergamo area with long-standing experience in compressed air generation and distribution. The consultant recommended using Teseo piping for the high technological content of the solution. Leveraging the cooperation with CGC and Teseo, the compressed air system, comprised of five kilometers of piping, was designed to meet the strictest energy efficiency standards.

“Meeting the customer’s requirements for 8 bar pressure, with minimum pressure drop and irregular consumption, we adopted HBS80 in the compressor room and for the main circuits, while for most cross lines we used HBS50,” said Piercarlo Guerini, owner of CGC. “The drop columns, made with HBS32 and HBS25 piping, were defined on-the-fly, in order to meet the specific requirements of each department; this approach was enabled by the great flexibility of Teseo’s system: the possibility to modify the system after the installation is essential in a building and an industrial area still in becoming. We have also added connections for the future monitoring of each unit, so that the company can monitor costs and assign them to each production order, pursuing the constant improvement of energy efficiency.”

Quality and flexibility

“The quality and flexibility of Teseo’s system, which we had the opportunity to appreciate in previous projects, were key factors in selecting the supplier,” commented Giuseppe Cividini, who supervised the refurbishment of the ex-Comital area. “Persico Spa’s mission is not production, but rather prototyping, as the latter pushes the limits of creativity always beyond what you think was possible. For this challenging project, we selected reliable, competent partners with a high-tech profile, who could effectively analyse our requirements and raise the bar.”

“We are not just happy with what we have done so far, we are already considering a new project for a 3300 sq m area where we would like to use Teseo systems for compressed air distribution and for vacuum as well,” added Cividini.
