Above the chillers and dry coolers of a data centre, warm exhaust air fights with cold intake air. Part of that warm air is drawn straight back in. The cooling plant delivers less, PUE rises and on hot days capacity has to be derated.

DataAirShield® is our answer: a carefully engineered second skin of technical mesh fabric above the roof that keeps warm air away from the intakes without pulling the fans off their operating point. Not a closed roof, not just any mesh, but a fabric whose pressure loss has been measured and whose structure has been designed for what it is: a building element.

Buitink Technology designs, manufactures and installs DataAirShield screens with the same seventy years of expertise we apply to textile façades, membrane roofs and ETFE cushion roofs. From the first CFD question to the last tension spring.

Why DataAirShield®

• Measured, not estimated. Pressure-loss data to EN 13030 per fabric type: direct input for the CFD study.
• A building element. Designed for wind and snow to Eurocode and CEN/TS 19102. Biaxially tested per roll of fabric.
• Fire safe to the standards. Fire classes M2 (NF P92-503) and B1 (DIN 4102-1), with certificates from accredited institutes.
• 10-year warranty. In writing, with a maintenance protocol. Comparable mesh fabric of ours has been outdoors for 20 years.

Who is this for?

M&E/MEP contractors, main contractors, steel contractors, consultants and data centre owners who have to specify, tender or build an air separation above chillers, dry coolers or cooling towers. We supply the pressure-loss data for the CFD study, can recommend a CFD specialist if required, and build the screen, on new and existing roofs.

We applied the same mesh-fabric principle as a permeable façade for a carbon-capture installation: see the textile façade for the CO₂ reduction plant in Alkmaar.
