Technical hygiene

Clean water, healthy air, safe technology.

For building operators, technical hygiene means much more than just cleanliness. It encompasses the hygienically safe operation of technical systems relating to building management (such as drinking water installations, ventilation and air-conditioning systems) in order to minimise health risks, comply with legal requirements and ensure the reliable operation of the building. Regular tests, maintenance and hygiene inspections help to identify hazards such as Legionella or indoor air contamination at an early stage and prevent them in the long term.

  • Drinking water tests: Enjoy drinking water with peace of mind
  • Indoor air hygiene tests Ensure healthy air with hygiene inspections in accordance with VDI 6022
  • Tests on evaporative cooling systems Prevent Legionella outbreaks through tests and risk assessments on evaporative cooling systems 
Hygiene Quick Tips

Are my systems subject to hygiene inspections?

Technical hygiene – safety starts with the details

Hygiene means far more than just cleanliness. It is a crucial factor in protecting people, ensuring the smooth running of buildings and complying with legal requirements. Whether in the catering industry, public facilities or the healthcare sector – wherever large numbers of people gather, technical hygiene is becoming increasingly important.

Modern buildings and facilities place high demands on planning, operation and maintenance. This also applies to drinking water systems, ventilation and air-conditioning systems, and hygiene-sensitive areas. Only through holistic approaches and regular inspections can risks be identified at an early stage and minimised in the long term.

With our expertise, we support you in reliably maintaining your hygiene standards – in a practical, standards-compliant manner and tailored to your sector. Use our Quick Checks to quickly assess the status of your systems and identify targeted measures.

Frequently asked questions about hygiene and infection control

Frequently asked questions about hygiene and infection control

Drinking water tests are mandatory for operators of larger domestic hot water systems. These include systems with a storage capacity of more than 400 litres or more than three litres of water in the pipework between the water heater and the final tap. Depending on usage, Legionella testing is required annually or at least every three years. Where the building is open to the public, an annual test is mandatory.

A hygiene inspection in accordance with VDI 6022 is required for newly installed ventilation and air-conditioning systems prior to commissioning, following significant modifications to the system, and for existing systems where an initial inspection has not yet been carried out. In addition, regular follow-up inspections are mandatory to ensure the system’s hygienic safety on an ongoing basis.

Training in accordance with VDI 6022 or VDI 6023 is required for persons who design, install, operate, service, maintain or carry out hygiene assessments of ventilation and air-conditioning systems or drinking water installations. This includes, in particular, operators, planners, engineers, technicians, master craftsmen and specialists in building services engineering.

HACCP certification helps companies in the food and drink industry to systematically identify and control food safety risks. It supports compliance with legal requirements, reduces liability and quality risks, strengthens the confidence of customers and consumers, and makes it easier to demonstrate adherence to recognised hygiene standards, including in international business.
