Product Introduction

Piezoelectric transducers vibrate beneath a controlled shallow water level and break the surface into microscopic droplets. Internal blowers carry the mist from the stainless reservoir through top outlets, where it evaporates into dry air. Because the system does not boil water, electrical demand is low and the evaporation also provides a modest cooling effect.

Key Features

High-frequency transducers create fine droplets without electric boiling elements.

Low power consumption makes the technology suitable for continuous high-duty humidity control.

A stainless reservoir, level control and periodic drain cycle manage the transducer water surface.

Modular transducer plates and accessible blower components can be serviced from the front.

Customer Product Concerns

Ultrasonic systems need clean feed water, adequate absorption distance and accessible transducers to avoid mineral dust or wetting.

Minerals in atomized mains water settle as white dust.Reverse-osmosis or demineralized feed water limits dissolved solids carried into the air.

Large droplets fall before evaporating and wet nearby surfaces.Correct transducer output and blower airflow produce fine mist within the available absorption volume.

Biofilm forms in stagnant reservoir water.Automatic flushing, controlled refill and accessible stainless tank surfaces support hygienic maintenance.

A failed transducer reduces output across the complete unit.Modular transducer plates allow the affected section to be replaced independently.
