Dual Cooling Water Cooling Vest: Engineering Heat Relief for Industrial Work
Dual Cooling Water Cooling Vest: Engineering Heat Relief for Industrial Work
As global temperatures rise, outdoor and industrial workers increasingly face heat stress that threatens both health and productivity. Conventional cooling measures—fans, misting systems, or simple ice packs—often fall short in mobility, duration, or effectiveness. The Dual Cooling Water Cooling Vest category addresses this gap by combining passive ice-pack cooling with active water circulation, offering a portable, long-duration solution for construction, traffic control, sheet metal factories, and other high-heat environments.

The Heat Stress Challenge in Industrial Settings
From metal roof factories to street vending and traffic direction, workers are exposed to prolonged sun and ambient heat. Traditional cooling vests relying solely on ice packs lose cooling capacity quickly, often within an hour, and require frequent re-icing. This disrupts work flow and offers inconsistent relief. The need for a long-lasting cooling vest that delivers sustained, comfortable body cooling without tethering workers to a power source is evident.
Shokunin’s COOLWAVE Water-Circulation Cooling Vest: Product Overview
Shokunin, the professional brand launched by FENG SHANG PRECISION CO., LTD. (established 2009 in Taoyuan City, Taiwan), introduces the COOLWAVE Water-Circulation Cooling Vest as an industrial cooling apparel classified under Personal Protective Equipment (PPE). Available in Basic Model and Professional Models (Black, Gray, Blue), the vest is engineered for construction and outdoor work scenarios. It operates through a water-circulation cooling system: two included ice packs chill a water reservoir, and a small pump circulates cold water through tubes running across the body.

Technical Specifications and Key Parameters
The cooling pump operates at a rated voltage of 5V and a maximum current of 150mA, delivering a flow rate of 320 to 370 ml per minute. According to the product specifications, the cooling duration is 3 to 4 hours, and the suitable ambient temperature is below 10°C. The net weight of the vest is within 2 kg, making it a lightweight cooling vest suitable for extended wear. Materials include a water bag made of TPU (Thermoplastic Polyurethane), a polypropylene water bag cap, sand rubber (black) cooling tubes, and shoulder straps of 600D polyester. Each unit includes the water-cooled vest backpack and two ice packs.
Application Scenarios Across Industries
The COOLWAVE vest is intended for construction workers, outdoor workers, food stall operators, street vendors, traffic controllers, and sheet metal factory workers. Real-world uses documented by the manufacturer include deployment at metal sheet factories, construction sites, and traffic control posts. The portable backpack design and adjustable straps allow workers to move freely while staying cool. For workers exposed to prolonged sun—such as street vendors or construction crews—the vest provides rapid cooling work vest functionality without the need for external power cords.

Market and Sourcing Considerations
FENG SHANG PRECISION CO., LTD. operates a 1000 m² manufacturing facility with an annual production capacity of 10,000 units. The company employs approximately 30 staff, including an R&D team of 5 engineers. Export business accounts for 50% of total sales, with major markets in the USA and ROC (Taiwan). The company markets its products under the Shokunin brand, which also produces air compressors, cut-off machines, diamond saws, and other professional tools. Buyers looking for a portable cooling vest or industrial cooling equipment can evaluate the COOLWAVE series as an OEM/ODM option for branded distribution.
Comparison with Traditional Ice-Pack Vests
Advantage: Active circulation over passive conduction
Traditional ice-pack vests rely on direct contact conduction; as the ice melts, cooling diminishes rapidly and unevenly. The COOLWAVE’s water-circulation system distributes chilled water continuously across the torso, providing more uniform and longer-lasting relief—up to 3–4 hours per ice pack change. The pump (5V, 150mA) can be powered by a small power bank, adding flexibility for power-bank cooling vest use.
Honest limitation: Temperature sensitivity
The vest’s specified suitable temperature is below 10°C. In extreme heat above that threshold, ice packs will melt faster, potentially reducing effective cooling duration. Users in very hot climates may need to carry additional ice packs or plan more frequent changes, though the circulation system still offers better comfort than passive vests in the same conditions.
Future Outlook for Water-Circulation Cooling Vests
As occupational safety regulations tighten and awareness of heat-related illness grows, demand for compliant, certified industrial cooling vest solutions is expected to rise. The COOLWAVE line, part of a broader portfolio from a Taiwanese manufacturer with 50% export share, positions itself as a candidate for procurement teams seeking reliable, manufacturable designs.
