The ultimate in reliability!
Certification according to VDI 6022
Another part of the DRAABE full-service package is the annual testing and certification of the air humidification system by the association of German engineers, or Verein Deutscher Ingenieure (VDI). This facilitates the compliance of the DRAABE systems at any time with the newest state of the art for direct room air humidification, as defined in the VDI 6022, Sheet 6.
In contrast to an isolated component test or general system certifications, the comprehensive VDI certification guarantees compliance with all the required hygiene measures, inspection intervals and limits whilst in operation.
Minimising liability risks
Section 4 of the German Occupational Safety Act requires the employer to take into account the state of the art in all measures concerning occupational safety. Should the state of the art intentionally or unintentionally not be observed, this can result in damage and a liability claim.
With the VDI certification planners, operators and users can document compliance with the occupational safety demands and the current state of the art.
The differences in marks of conformity
Confirms the compliance with general European safety regulations, (e.g. machine directive). Prerequisites for the DGUV mark of compliance.
DGUV Test Mark
Confirms that an air humidification system meets the requirements of the German statutory accident insurance. Prerequisite for the VDI certification.
The basic requirements for a VDI certification is that the systems comply with the general requirements of the German Social Accident Insurance or Deutschen Gesetzlichen Unfallversicherung (DGUV). Then all the devices, parts and components are further checked by VDI certified engineering experts for proper function and operating safety. Only then can an on-site certification be issued to the user:
The water quality and all relevant microbiological limit values are tested and documented as part of the certification:
1. The piped in water for the humidifiers has to meet at least drinking water quality standards with regard to microbiology. Some of the test items are the water parameters of i.e. PH-value, turbitity and temperature.
2. The humidifying water at the system border to the room (e.g. nozzle outlet) has to meet all the required limit values.
Periodic checking of the actual air quality in the humidified room is part of the comprehensive inspection. The microbiologic components of the room air (e.g. mould spores, bacteria) are tested, counted and evaluated with standardised procedures.
Changes in the use of the space (e.g. machine density) or of the room properties (expansion, room electronics, etc.) can have a significant effect on the operation of a direct room humidification system. The testing scope therefore also includes checking accessibility of all relevant system components, the unimpeded moisture distribution in the room, and possible heat sources that could be the cause of microbiological growth.
Why is a VDI certification so important?
Is the most comprehensive test on the manufacturer as well as user side
"Occupational safety is part of our mission statement. The VDI-certification was therefore a must for us."
“With DRAABE I have the reliable air humidification that I need and I do not have to take care of anything myself.”
