          A new trigeneration plant serving the production facility has given rise to a partnership between Cefla and the customer, marking a step forward in power generation.

Strengths

Customised energy solution:

Cefla has built a turnkey trigeneration plant for Nupi Industrie Italiane, integrating electricity, heat and cooling production to optimise the factory's production processes.

Plant innovation

The plant uses a methane-powered internal combustion engine coupled with an ammonia absorber, enabling the production of cooling energy at low temperatures, down to -40°C, ideal for the industrial needs of Nupi Industrie Italiane.

Advanced energy efficiency

The adoption of heat recovery systems from exhaust gases and engine cooling water allows for significant energy savings and a reduction in CO₂ emissions.

Key Numbers

1 MW

Installed electrical power

approximately 2,100 tonnes/year

Reduction in CO emissions

30% compared to traditional solutions

Estimated total energy savings

Background

Nupi Industrie Italiane is a leading manufacturer of technopolymer pipes for industrial applications. The plant in Busto Arsizio needed an efficient and sustainable energy solution to support its extrusion and moulding processes, which require high levels of heating and cooling energy. Cefla responded to this need by designing and building a customised trigeneration plant.

        
          The building, which has seven floors above ground and three basement floors, features spacious executive offices and meeting rooms.

Challenges

Integration into an active production site
The plant was installed without disrupting production activities, requiring careful planning and targeted actions.
Adaptation to specific heating and cooling requirements
The plant was designed to provide heating and cooling energy in a flexible manner, adapting to variations in process loads.
Use of innovative materials
NIRON PREISOLATO technopolymer pipes were used for the distribution of heat transfer fluids, an innovative choice compared to traditional metal materials, ensuring lightness, durability and ease of installation.

Project Tasks

Cefla handled all phases of the project, from design to commissioning, carrying out:

Installation of a 1 MW methane gas-fired internal combustion engine coupled to an alternator for electricity generation.

Heat recovery from exhaust gases and engine cooling water for thermal energy production

Use of an ammonia absorber for low-temperature refrigeration energy production for cooling extrusion systems
Implementation of hot and cold distribution networks using NIRON PREISOLATO technopolymer pipes

Implementation

The project was completed in 2018, on schedule and within budget. The plant has enabled Nupi Industrie Italiane to improve the energy efficiency of its factory, reduce CO₂ emissions and optimise production processes thanks to a flexible and reliable energy supply.
Technopolymers and plant engineering challenges in the era of energy optimisation
The plant is powered by natural gas and electricity is produced by an internal combustion engine connected to an alternator. Through a lithium bromide absorber, the thermal energy produced by the system is in turn transformed into cooling energy, which is used to cool the extrusion plants used in the factory. What makes this plant the first of its kind is that pre-insulated NIRON technopolymer pipes have been used instead of traditional steel pipes.
Cefla's pre-insulated pipes were used to convey the heat transfer fluid to the users, creating a heating network that allows the necessary calories to be transferred to the company's heating plant, and a cooling network for conveying refrigeration to the users: refrigerators and injection moulding machines used to mould our products. The system allows the water to reach the systems at almost the same temperature as when it leaves the heating and cooling plant.
This innovative system of pre-insulated pipes and fittings is ideal for applications where reducing heat loss is of paramount importance.
In addition to their excellent technical performance, NIRON pipes are lighter than steel pipes and require easier processes for fixing joints. This has greatly simplified handling and installation, with significant savings in construction time. The plant, which came into operation nine months after obtaining the necessary authorisations, has become a case study for its efficiency.
