Pressure Fog^® is Armstrong’s most efficient high pressure atomizing humidification solution. Pressure Fog^® efficiently produces a rich fog to raise relative humidity without the need of an air compressor, keeping energy costs low and environments cool. Pressure Fog^® is a humidifying system that is ideal for applications that require high water volume with minimum energy use.

PressureFog® high pressure atomizer boosts the pressure of softened or purified tap water to 5-7 MPa with a plunger pump. The pressurized water is then sent through pipelines to specific nozzles, where it is atomized by fast swirling and sprayed to air in 5-15μm fog particles. The super fine fog particles absorb heat from ambient air and convert themselves from liquid state to vapor, resulting in increased air relative humidity (RH) and decreased air temperature. The humidification is an adiabatic process. PressureFog® atomization system can produce vast amount of fog particles without compressed air to raise air RH and cool down environment, as well as save energy cost.
