The Hay-kozé accessory is securely mounted on a safety hat. It is impact resistant and shock absorbent, and targets the hottest biometric areas during physical activity –the back and sides of of the neck, and the upper back – and prevents headaches. This efficient, targeted cooling technology requires less energy consumption than other solutions. Owing to the lower power requirement, our product operates at only 30 decibels, which is comparable to a whisper. It is also designed to be obstruction-free, allowing 100% flexibility of head movement and minimizing hindrances while performing physical labour. It is equipped with thermostatic sensors to track the workers’ body temperature, enabling auto-windspeed adjustment, and can be integrated into the central IoT monitoring system of construction sites.
