Importance of Hygienic Air Handling Unit
What Is A Hygienic Air Handling Unit?
Hygienic air handling units are used in surgical operating rooms, clean rooms, food, medicine, and chemistry facilities, and in similar places where sensitive sterile conditions are required. The supplied air is managed by the air handler to control strict room climate conditions, with the ultimate goal of creating an environment promoting higher levels of sanitation while hindering bacteria growth and spread.
What Happens Inside The Air Handling Unit?
- Growth of microorganism colony on non-metallic parts over the period of operation
- Corrosion on metallic parts
- Accumulation of dust/foreign material and remains there,
- Does not have sufficient space for cleaning its components
- High leakage rate.
- Inefficient thermal bridging.
- Low casing strength.
The main differences between regular ahu and hygienic ahu are:
- The hygienic components and smooth surfaces avoid humidity and the development of micro-organisms (EN ISO 846:2019)
- The structure and casing respects norms & standards ( In accordance with EN1886 & DIN 1946-4 and VDI 6022-1).
- The efficiency in filtration
- The technology of micro-organism reduction
