Zitrón’s facilitiesZitrón’s facilities

Processes and systems to provide better value to clients

Zitrón’s manufacturing operations were initiated in 1963, in a facility built on the outskirts of Gijón, in the Spanish province of Asturias. That location remains the company’s global head office, but over time, the original facility has been modernised several times and has expanded to include additional manufacturing facilities and administrative offices spread over a much larger area.

R&D investment, a commitment to innovation and a willingness to embrace new technologies, materials and processes have been integral elements of Zitrón’s growth since its founding and have been instrumental in positioning Zitrón where it is today, namely, the benchmark for underground ventilation solutions, covering both products and services.

Zitrón’s passion for excellence and success means that we are fully committed to Industry 4.0 principles. We aim to be at the forefront of implementing them and to thus ensure that our customers derive all the productivity, efficiency and cost saving benefits that Industry 4.0 can deliver.

We will continue to embrace change and to invest in ensuring that all our facilities are state-of-the-art, incorporate the latest proven technologies and fully complement the implementation our cutting-edge Manufacturing Execution System, which will deliver enhanced control of production, traceability and shorter delivery times.

Zitrón’s Test BenchZitrón’s Test Bench

The world’s biggest aerodynamic test bench for ventilation systems in underground infrastructures and mines

This cutting-edge facility is the largest one in the world. It is also an approved Laboratory of AMCA, where any fan up to 2,500 kW and 5.8 m diameter is tested at its nominal point (real operation condition). It is 100m in length and has cross-section of 52 m2. The level of performance tolerance reached is AN1.

This kind of full scale test can reproduce any ventilation circuit parameters – flow, pressure, efficiency, vibrations, temperature, etc. – specified by the customer. This testing can cover not only the initial underground conditions but also potential situations that might arise during the lifespan of the projects.

*AMCA (Air Movement and Control Association International, Inc.). A leading independent non-profit organisation that is responsible for establishing and certifying companies that meet the quality standards regarding heating, ventilation and air conditioning systems.
