The nanoe X generator, jointly developed by JR East Technology Co., Ltd. (hereinafter, JR East Technology) and Panasonic Corporation (hereinafter, Panasonic), has been adopted in Sagami Railway Co., Ltd.'s (hereinafter, Sagami Railway) new '13000 series' trains, which began operation on March 30, 2026 (Monday). This marks the first time that nanoe X, which offers enhanced effects, has been adopted in Sagami Railway vehicles, following the introduction of nanoe generators in the '20000 series' and '12000 series' trains.
Panasonic's nanoe (※1) is a nano-sized particulate ion generated by applying high voltage to moisture in the air, containing OH radicals that easily react with various substances. nanoe X enhances the generation of these OH radicals by 10 times compared to conventional nanoe, offering diverse effects such as deodorization (※2), and suppression of allergens like bacteria (※3) and pollen (※4).
Railway vehicles present a unique environment with frequent door openings and passenger traffic, as well as long, narrow, and wide spaces. To maximize the effectiveness of nanoe, it is necessary to control its uniform dispersion throughout the vehicle. Therefore, JR East Technology and Panasonic collaborated to develop optimal control for railway vehicles, with JR East Technology integrating a control power supply unit into Panasonic's nanoe X device for product commercialization.
The '13000 series' trains are designed based on the concept of "Safety × Security × Elegance × Future" and feature an open car interior. Building on the proven track record of nanoe generators in the '20000 series' and '12000 series', nanoe X was adopted to provide an even more comfortable air environment, aiming to further enhance comfort.
JR East Technology and Panasonic will continue to evolve nanoe technology specifically for railway vehicles, providing clean and comfortable railway car spaces.
※1 Compared to general ions, nanoe has approximately 6 times* longer lifespan, allowing it to spread over a wider area. Its moisture content is approximately 1,000 times** (by volume) or more than air ions, and it is a mildly acidic ion gentle on skin and hair.
