Uboldo (Varese), 16 March 2026 – LU-VE S.p.A., a multinational company based in Varese and listed on Euronext STAR Milan, and one of the world’s leading manufacturers of air heat exchangers, has supplied evaporators for the cooling system of the data centre in the Táctica Business Park in Paterna (Valencia): the first in Spain – and among the very first in the world – to use CO₂ as a refrigerant.

CO₂ is a natural refrigerant fluid with high thermodynamic efficiency and minimal impact on global warming and the greenhouse effect. LUVE was among the first companies to adopt this refrigerant back in 2004, for the first time globally, in a supermarket refrigeration plant in Wettingen (Zurich, Switzerland).

The data centre – developed by KUMO Networks, a company controlled by El Corte Inglés and focused on highly sustainable data centres – covers an area of 1,000 sqm and has been designed according to Tier IV quality standards, the highest level in data centre classification. This ensures maximum operational continuity: a fully fault‑tolerant infrastructure, redundancy in every component, and 99.995% uptime (equivalent to a maximum of 26.3 minutes of downtime per year).

For this project, LUVE specifically developed evaporators that use CO₂ as a refrigerant in a transcritical cycle.

This is the first time in Spain, and among the earliest in the world, that this natural refrigerant has been employed for a large-scale data centre.

LUVE supplied 34 evaporators, 64 dual‑airflow evaporators and 4 angular air coolers. These are high‑performance industrial air coolers, specifically designed for CO₂ applications at medium and high temperatures. The systems extract the hot air produced by the data centre equipment and generate a cold airflow directed toward the IT equipment racks.

The Paterna data centre has a cooling capacity of 1.5 MW and is powered by one of the largest geothermal fields in the Valencian Community, which will help maintain CO₂ at its most efficient temperature during the hottest months.

The waste heat produced by the data centre’s cooling systems is recovered and used for the local district heating network, supplying nearby buildings.

Commissioning of the data centre at the Táctica Business Park in Paterna is scheduled in the coming weeks.
