Alpen Co. has developed a mist cooling system that lowers temperatures without leaving moisture on the skin [1, 2].
This technology addresses the growing risk of heatstroke during extreme summer heat waves. By preventing the damp feeling typically associated with misting systems, the company aims to provide a more comfortable and effective cooling solution for public spaces [1, 3].
The system utilizes ultra-precision nozzles with a diameter of 0.1 mm [2]. These nozzles break water into extremely fine particles that evaporate rapidly, preventing the mist from adhering to the skin [2, 3]. This precision allows the system to cool the surrounding air while keeping users dry.
The technology was featured on the television programs "Good! Ichioshi" and "Good! Morning" on July 19 [2]. Following the broadcast, the system is scheduled for a three-day exhibition starting July 24 [4]. These demonstrations will take place at venues including the Tokyo Big Sight in Tokyo and locations in Fukuoka City [4, 5].
Development of the system comes amid rising concerns over heat-related fatalities. Data indicates that 1,681 people died or were injured due to heatstroke in 2025 [6]. The company designed this specific cooling method to reduce such risks by providing a non-intrusive way to lower ambient temperatures in high-traffic areas [1, 4].
Alpen Co., led by President Atsuyuki Mizuno, is positioning the technology as a critical tool for urban heat management [1]. The company has also been involved in educational efforts, including heatstroke prevention classes attended by 38 students [7].
“The system utilizes ultra-precision nozzles with a diameter of 0.1 mm.”
The development of a 'dry' mist system represents a shift toward high-precision engineering to solve public health challenges. By eliminating the physical discomfort of wet skin, the technology removes a primary barrier to the widespread adoption of outdoor evaporative cooling, potentially increasing the usage of such systems in densely populated urban centers to combat rising global temperatures.
