Semiconductor Cooling Vest with 2 Cooling Modules and 2 Fans for Hot-Weather Work
Active Cooling for Hot-Weather Work
Stay Cool Through Hot Shifts
A semiconductor cooling vest with two Peltier modules and two airflow fans that brings active temperature relief to high-temperature workplaces.
How It Works
The vest uses semiconductor (Peltier) modules to move heat away from your skin. Each module sits against the body and works with an attached fan to carry the heat away. Five temperature settings let you choose the cooling intensity, from a light breeze to strong active cooling for the hottest jobs.
Where It Fits
- Factory workshops, welding and smelting environments
- Warehouse and logistics work in hot weather
- Outdoor maintenance, inspection, construction and fishing
