The group's principal activity is to develop, manufacture and sell ultrasonic liquid atomizing nozzles. The ultrasonic nozzle systems atomize low to medium viscosity liquids by converting electrical energy into mechanical motion in the form of high frequency (ultrasonic) vibrations which break liquids into minute drops that can be applied to surfaces at low velocity. The group has diversified its product offerings to provide coating systems to medical device manufacturers and to provide components for coating systems for surface acoustic wave wafers used in sensors. The group markets its products in the United States, western Europe, Far East and other foreign countries.
