229 million construction workers face 19,000 heat-related deaths and 22.85 million occupational injuries annually—a crisis intensifying with rising temperatures [ILO]. Our patented solution is the Air Ring 49 (AR49), the world’s first and award-winning, contactless biomedical cooling accessory for helmeted workers to prevent heat strokes and recover expensive hours of productivity. At just 155g, AR49 is tested to cool critical head hotspots by up to 5.1°C, headache-free, delivers 15 hours of power, and adapts to any helmet with our proprietary Smart-lock. Unlike bulky and unstable waist fans or sweat-soaked cooling jackets, it’s ergonomic, agile, and maintenance-free. With over 370 units ordered/deployed by leading contractors including China State and FSE Engineering, and awarded the prestigious James Dyson Award, AR49 reshapes the $49B cooling device industry. In a leap towards our vision to free all outdoor-goers from climate change, we have expanded the Air Ring to all types of casual headwear, and developed the IoT-enabled Air Ring 50 with multi-variable health sensors —unlocking safer, more agile lifestyles worldwide.
