We are proud to announce that our plate heat exchangers have officially passed VDI 6022 certification, demonstrating our commitment to maintaining the highest hygiene and safety standards in ventilation technology.

🔍What is VDI 6022, and why does it matter?

VDI 6022 is one of the most comprehensive European standards for ensuring hygienic air quality in HVAC systems. It sets strict requirements for the design, materials, cleanability and microbiological safety of ventilation components used in sensitive environments such as hospitals, schools and public buildings.

🧪 Certified according to multiple international hygiene standards:

Our testing and validation covered compliance with the following standards:

✅ VDI 3803, sheet 1 (05/2020)

✅ DIN 1946, part 4 (09/2018)
