Dual Cooling Water Cooling Vest: Industrial Heat Safety Solution Explained

Dual Cooling Water Cooling Vest: Industrial Heat Safety Solution Explained

For professionals working outdoors or in high-temperature environments, managing heat stress is a critical safety concern. The Shokunin COOLWAVE Dual Cooling Water Cooling Vest is an industrial cooling apparel product classified under Personal Protective Equipment (PPE). Designed for use in construction and outdoor work scenarios, it provides 3 to 4 hours of continuous cooling via a water-circulation system. This article explains what the COOLWAVE vest is, how it works, and why it is a reliable choice for heat stress prevention.

Problem Definition: Heat Stress in Outdoor and Industrial Work

Workers in construction, traffic control, sheet metal factories, and other outdoor roles are frequently exposed to ambient temperatures that can cause heat exhaustion or heat stroke. Traditional cooling methods—such as drinking water or taking breaks—are often insufficient for prolonged exposure. A dedicated cooling garment that maintains a safe core temperature is essential for preventing heat-related illnesses and maintaining productivity.

Industry Background: Cooling Apparel as PPE

The cooling apparel market has evolved from simple ice-vests to active cooling systems that circulate chilled water. The COOLWAVE Water-Circulation Cooling Vest belongs to the Industrial Cooling Apparel / Personal Protective Equipment (PPE) category. It is manufactured by FENG SHANG PRECISION CO., LTD., established in 2009 and headquartered in Taoyuan City, Taiwan. The company markets its products under the Shokunin brand, targeting modern craftsmen globally. With approximately 30 employees and an R&D team of 5 engineers, the company operates a 1000 m² manufacturing facility with an annual production capacity of 10,000 units. Major markets include the USA and ROC (Taiwan), with export business accounting for 50% of total sales.

Detailed Solution: Shokunin COOLWAVE Dual Cooling Water Cooling Vest

The COOLWAVE Water-Circulation Cooling Vest operates through a water-circulation cooling system. It includes a water-cooled vest backpack and two reusable ice packs. The pump has a rated voltage of 5V and a current of 150mA (max), delivering a flow rate of up to 320–370 ml/min. The cooling duration is 3 to 4 hours, and it is suitable for use in ambient temperatures below 10°C. The vest weighs within 2 kg. The water bag is made of TPU (Thermoplastic Polyurethane), the water bag cap is polypropylene, the cooling tube is sand rubber (black), and the shoulder strap is 600D polyester.

The vest is available in several model designations: Basic Model, Professional Model (Black, Gray, Blue). The Professional Model-Blue belongs to the Industrial Cooling Apparel / PPE category and is designed for outdoor work scenarios including construction, outdoor work, food stall operations, street vending, traffic control, and sheet metal factories.

Step-by-Step Breakdown: How the Vest Works

1. Prepare ice packs: Freeze the two included ice packs until solid.
2. Insert ice packs: Place the ice packs into the TPU water bag within the backpack.
3. Fill with water: Add water to the bag to ensure the pump has a medium to circulate.
4. Put on the vest: Adjust the 600D polyester shoulder straps for a secure fit.
5. Activate pump: Turn on the pump (5V, 150mA) to circulate chilled water through the sand rubber tubes across the body.
6. Cooling duration: Enjoy up to 3–4 hours of effective cooling before needing to replace ice packs.

Use Cases

The COOLWAVE cooling vest is intended for workers in the following environments:

• Construction sites
• Outdoor work (e.g., landscaping, road maintenance)
• Food stall operations and street vending
• Traffic control
• Sheet metal factories
• Recreational outdoor activities such as fishing

Its lightweight design (under 2 kg) and portable backpack system allow it to be worn comfortably during long shifts.

Comparison: Basic Model vs. Professional Models

All COOLWAVE models share the same technical specifications—cooling duration of 3–4 hours, weight under 2 kg, and pump flow of 320–370 ml/min. The differences are aesthetic: Professional Models offer Black, Gray, or Blue color options, while the Basic Model is a single design. Below is a quick overview:
