- Evaporative Cooling Clothing: Uses evaporative fabric that leverages moisture evaporation to lower surface temperature, offering a lightweight, reusable option for outdoor construction, logistics, and warehousing where portability is the priority.
- Phase Change Cooling Clothing (PCM): Employs high-capacity phase change material inserts, such as ice/gel packs, delivering stable cooling for over 4 hours without any power requirement—well suited to foundries, smelting workshops, and metallurgy sites where batteries are impractical.
- Fan Cooling Clothing: A dual-fan active ventilation system compatible with 5V, 7.4V, and 12V battery configurations, with 3-speed control to let users regulate cooling intensity; deployed in outdoor construction, power plants, and shipbuilding.
- Semiconductor Cooling Clothing: Built on Peltier effect refrigeration chips for immediate tactile temperature reduction, capable of operating up to 49 hours with specific battery packs on a 12V high-efficiency system—suited for precision manufacturing, petrochemicals, and long-shift industrial operations.
- Vortex Tube Cooling Clothing: Applies vortex tube thermodynamics to convert compressed air into cold air streams, providing continuous, infinite cooling at fixed workstations such as steel plants and welding stations as long as air supply is maintained.
- Water Circulation Cooling Clothing: Circulates chilled water through an integrated pump and tubing network for uniform torso cooling in foundries, smelting, and specialized industrial workshops facing intense radiant heat.
Across this platform, cooling activation occurs within 10 seconds, and the company's technology spans Phase Change Materials (PCM), Peltier effect refrigeration, and Vortex Tube thermodynamics—giving it specialized solutions even for environments without electrical power.
