Semiconductor Cooling & Heating Vest for High-Temperature and Cold-Weather Work
Active Cooling for Hot-Weather Work
Stay Cool in Extreme Heat, Warm in Winter Shifts
A semiconductor cooling and heating vest with four Peltier modules that brings active temperature control to high-temperature workplaces.
How It Works
The vest uses semiconductor (Peltier) modules to move heat away from your skin. Press and hold the button to turn it on — the LED shows white for energy-saving mode, which cools for 10 minutes and pauses for 2 minutes while the fan keeps running. Press the button to switch between high (red), medium (blue), and low (green) settings. Press and hold to turn off; the fan continues for about a minute to clear residual heat.
The cooling modules are detachable and can be arranged as needed — install 2, 3, or 4 modules on your vest. The Cooling Module Set ships with 4 modules, so you can replace or expand your setup, or use the modules on another compatible vest.
Where It Fits
- Factory workshops, welding and smelting environments
- Warehouse and logistics work in hot weather
- Outdoor maintenance, inspection and construction shifts

Cooling Module Set
The Cooling Module Set includes 4 cooling modules with connecting cables. It is designed for the cooling and heating vest above, and can also be installed on another compatible vest. The set ships without a battery or controller — the modules connect to the vest's existing control system.
Use & Care
- Power through a 5V USB source; a 20,000 mAh power bank is recommended for longer run time.
- Allow the vest to dry before storage after use in humid conditions.
- Keep the connectors and modules dry; do not submerge the vest or its electronics.
Frequently Asked Questions
How long does the vest run on a power bank?
Run time depends on the power bank capacity and the selected mode. As a guide, a 20,000 mAh power bank supports roughly 5–8 hours in typical use depending on the temperature setting.
Does the vest come with a battery?
No. The vest connects to your own 5V USB power source, such as a power bank, so you can choose the capacity that suits your shift length.
Can I use the vest for both cooling and heating?
Yes. The same vest provides active cooling in hot conditions and a heating mode for cold-weather work, with four temperature settings in each direction.
Can I buy just the cooling modules?
Yes. The Cooling Module Set includes 4 cooling modules with connecting cables and ships without a battery or controller. It works with this vest and can also be installed on another compatible vest.
How many modules can I install?
The vest supports 2, 3, or 4 modules depending on how you arrange them. Each set ships with 4 modules.
Is it suitable for welding or workshop use?
The vest is designed for high-temperature work environments such as factory workshops, welding, smelting, warehouse and outdoor jobs. Always follow workplace safety requirements when working near heat sources.
