Murata Ionissimo® Ionizer/Ozonizer Modules
These modules offer higher ion output and better control of ozone output in air cleaning equipment
The Murata Ionissimo® family of modules uses high-voltage discharges to ionize or ozonize air molecules. The Ionissimo® modules are widely used in air purification, bacteria removal, deodorization, static charge elimination and electrostatic charging.
Medical research indicates that ionizers and ozonizers may also be able to play a part in new forms of air-cleaning equipment intended to destroy particles of the SARS-CoV-2 virus in indoor air.
Murata’s compact Ionissimo® modules are capable of generating a large number of ions, and concurrently producing ozone. Without affecting ionization, the quantity of ozone generated can be controlled to the optimum level for a specific application, such as disinfection of air.
Benefiting from unique high-voltage technology and an innovative structural ion element design, the Murata Ionissimo® ionizers are smaller and more efficient than conventional ionizers. An Ionissimo® module comprises an ion generator connected to a dedicated power supply, providing a complete system which is easy to integrate into end product designs.
Murata also supplies the MHM500 series of ozonizers for humidifier applications. The MHM500’s ozone generator section is highly reliable: it includes an internal heater to keep the surface of its substrate dry. It is also one of the smallest creeping-discharge types in the industry.
