Hygiene inspections

An uncomfortable indoor climate can cause malaise

Air, surface and radiation temperature, humidity and air velocity are parameters that influence our well-being. Therefore, it is important to ensure a comfortable indoor climate when operating HVAC systems. We assess your indoor climate for comfort and offer suggestions for improvement.

We offer all-in-one solutions

If you suspect that your HVAC system is causing such problems, we can offer a competent and cost-efficient examination of your HVAC system and the relevant air-conditioned rooms.
We will gladly assist you in the design of new HVAC systems and if needed, offer redevelopment concepts for your existing system.

Our services include

  • Initial hygiene inspections and follow-up inspections of HVAC systems in accordance with VDI 6022
  • Type testing of HVAC systems and their components according to VDI 6022
  • Physical measurements of climate parameters air temperature, relative humidity, air velocity etc. at representative points of your HVAC system and/ or the air-conditioned rooms
  • Measuring of various microbiological parameter, such as general colony counts, legionella, pseudomonas aeruginosa in humidifier, feed and cooling water
  • Extraction and analytics of contact culture samples of HVAC system surfaces in order to determine the contamination with bacteria and moulds
