Reliable air conditioning technology
for sensitive areas
In hospitals, especially in operating rooms, hygiene is a top priority. Accordingly, hospitals also have special requirements for the ventilation of their buildings.
Airbox air handling units in hygienic design according to DIN 1946/4 meet these requirements exactly.
Hygienic design in accordance with DIN 1946/4
- The surface design must not promote the accumulation of dirt deposits.
- The materials used must be resistant to disinfectants and abrasion.
- Side walls and all components exposed to air flow must be hot-dip galvanised and coated.
- The floor, including slide rails that come into contact with condensate, must be made of stainless steel or aluminium.
- Closed-cell seals.
- All permanently installed components must be accessible via operating openings.
- All components must be protected against contamination and damage during the construction period.
- Only condensate trays with a slope on all sides may be used.
- Sight glass and lighting are required for filter and fan units.
- 2- or 3-stage filtration depending on room class
- Filter replacement only permitted on the dust air side
- For filters with antimicrobial coating, proof of effectiveness and toxic safety is required
- Filter differential pressure monitoring without barrier fluid
- Only closed-pore sealing profiles may be used
- Heater frame made of galvanised steel, fins made of aluminium/copper or galvanised steel
- Cooler frame made of stainless steel or aluminium (AlMg), coated fins, aluminium (AlMg) or copper, collector made of copper
- All parts in the wet area must be cleanable
- All condensate connections must be located on the same side
- Cooler must be visible from both sides
- Coil spacing cooler at least 2.5 mm
- Surface finish of rotor or plate exchanger: Galvanised and coated frame, epoxy resin-coated or aluminium blades
- Stainless steel trays on the supply and exhaust air side
- Heat recovery systems must be installed on the supply air side after the first filter stage
- In rooms where cross-room recirculation is not permitted, only systems that prevent the transfer of substances from the exhaust air to the supply air are permitted
