IRIS OHYAMA Inc. (Headquarters: Sendai City, Miyagi Prefecture; Representative Director and President: Akihiro Oyama) will sequentially launch the "Inverter Portable Cooler 2.3/3.5kW," which is the company's first portable cooler equipped with an inverter to achieve low-noise operation, from April 30, 2026, primarily at electronics retailers nationwide and also at home centers.
In recent years, due to the effects of global warming and the urban heat island phenomenon, extreme heat has become commonplace. Consequently, the number of people considering portable coolers that can be installed without construction and used immediately after purchase is increasing, especially in places where outdoor units cannot be secured, wall construction is difficult, or when air conditioner installation is delayed during busy construction seasons. According to a survey conducted by our company, bedrooms are the most common place of use, accounting for approximately 30% (※1), while dissatisfaction with quietness was the most frequent complaint, indicating that many users are unhappy with operating noise (※2).
The newly released "Inverter Portable Cooler 2.3/3.5kW" is the first portable cooler from our company to be equipped with an inverter that controls excessive cooling and operation. This allows users to switch to low-noise operation, suppressing operating noise to less than 45dB with a single button during cooling, making it easy to use even during sleep when noise is a concern. Furthermore, by suppressing internal heat generation through inverter control efficiency, it achieves the company's highest operating temperature range of up to approximately 45 degrees Celsius, allowing it to be used even in environments with high room temperatures during extreme heat.
In addition, a window panel that can be installed without tools allows exhaust heat to be released outdoors, suppressing room temperature rise and efficiently cooling the interior. Even if there is no window at the installation location, the included gap attachment can be installed on doors or sliding doors to efficiently release exhaust heat into the hallway. Other features include an auxiliary lock for security, a shutter to prevent insects and rainwater from entering from outside, and a rain cover.
IRIS OHYAMA will continue to develop products closely tied to consumers' daily lives, contributing to the realization of comfortable living.
