Airtec® HydroSens AHU  Duct Humidification

Airtec® HydroSens AHU HAVAC Humidification

Adiabatic modular high-pressure nozzle system for duct and exhaust air cooling, designed according to VDI 6022. Designed for lowest power consumption at very high efficiency and low water loss by a frequency-controlled high-pressure atomization.
The system contains only inert components. The hygiene concept waived in accordance with VDI 6022 on stationary or circulating water as well as porous, water-storing elements.
The high-pressure nozzle system works without any chemical or biological additives. Regular, consuming and costly monitoring and metered disinfectants is completely eliminated by the hygienic concept and unique design.
