The Model 5515 Ceiling Emitter and Controller Models 5522/5582 comprise our state-of-the-art digital room ionization system. Digital technology allows each ceiling emitter’s parameters, including ion output, ion pulse timing or digital address, to be either individually set at its location using the Model 5571 and Model 5572 handheld controllers, or remotely set through IonManager Pro when integrated with the software. Precision fine tuning of each ceiling emitter enables the ionization system to achieve maximum performance in any airflow condition and for each application.
