VDI 6022- HVAC systems and indoor air quality

VDI 6022-compliant hygiene inspections ensure that your HVAC systems meet the current standards. We create clarity and transparency for you with our clear documentation: That way, you minimise follow-up costs.

HVAC systems and indoor air quality Transparency with the Gesec® signalling system: The clear documentation of our hygiene inspections gives you a summary of all findings at a glance. After the hygiene inspection, you will know immediately where everything is OK (white) with your HVAC systems, where rectification of a shortcoming will be needed soon according to the standard (yellow) or where there is a need for immediate action (red) after the hygiene inspection. 

Experience from several thousand hygiene inspections confirms the need for a comparative airborne germ measurement on indoor and outdoor air.
