Investments & projects
Lasting growth requires strategic investment. From the 2016 facility expansion to the strategic partnership with Kolektor ETRA in 2020 — every investment has been a step towards long-term excellence.

Investment areas
Four strategic areas that define our development.
Infrastructure & facility
Purchase and modernisation of our own facility, capacity expansion, procurement of overhead cranes and shot-blasting equipment — the material foundation for reliable production.
Technology & equipment
CNC cutting machines, modern welding lines, our own NDT laboratory and ISO 12944 CX-class paint shop — equipment that ensures top quality.
Digitalisation
ERP system implementation, digital documentation, real-time process tracking — transformation towards Industry 4.0.
People development
Continuous training, certification programmes for welders and NDT inspectors, clear advancement paths and a safe working environment.
Collaborative MAG Robot (Cobot)
In line with our continuous efforts to modernise and improve the production process, we have implemented a collaborative MAG robot (Cobot) in the welding process for transformer tanks. This investment represents a significant step towards automation and digitalisation in accordance with Industry 4.0 principles.

Key benefits
Increased productivity
The robot enables continuous operation with consistent weld quality, eliminating downtime and fatigue.
Precision and repeatability
Every weld is executed with identical accuracy, reducing the need for post-weld corrections and warranty claims.
Improved occupational safety
Operators are increasingly shielded from potentially hazardous working conditions thanks to automated execution of critical operations.
Cost optimisation
Reduced waste, downtime and warranty claims directly improve the competitiveness of our products on the European market.
Production flexibility
The Cobot rapidly adapts to different geometries and assembly sizes, making it ideal for our range of transformer tanks.
650 kW photovoltaic power plant
Under the Modernisation Fund, we implemented the project Construction of an integrated photovoltaic (solar) power plant in grid-connected (on-grid) mode for own consumption. The installed solar plant has a rated output of 650 kW and comprises 2,376 photovoltaic modules with a total capacity of 974.16 kWp. The electricity produced is used primarily for the facility's own consumption, reducing grid dependency and accelerating our path towards CO₂ neutrality by 2030.

Kolektor ETRA group
Since 2020, PrimaBiro has been part of the Kolektor ETRA group — a Slovenian industrial leader with long-standing experience in the energy sector. This strategic partnership brings access to new markets, shared knowledge and long-term financial stability.
Bell type tank for Kolektor ETRA
For our strategic partner Kolektor ETRA, we designed and manufactured a transformer tank in a bell shape — a so-called bell type tank — for the very first time. This specific design requires high welding precision and special technological preparation. The welding was carried out entirely in our facility, and the project was successfully completed and delivered to the client.
