What is CoolTime?


Coller timer fan is an innovative wearable neck cooling device that utilizes advanced Phase Change Material (PCM) technology originally developed for NASA space applications. Unlike traditional cooling towels or battery-powered fans, this cooltime air conditioner alternative provides consistent cooling through scientific heat absorption principles.
The device works by absorbing body heat when placed around the neck, where major blood vessels are close to the skin surface. This creates a systemic cooling effect throughout the entire body. The cool time ice technology requires simple activation in a freezer or ice water, then provides 40 minutes to 2 hours of continuous cooling relief.
Cool ice fan targets anyone dealing with excessive heat – from construction workers and healthcare professionals to menopausal women experiencing hot flashes. The award-winning Korean design has gained recognition for its ergonomic comfort and zero-condensation cooling fan, making it suitable for both professional and recreational use.
