Shokunin COOLWAVE Dual Cooling Water Cooling Vest: Certified Industrial Heat Stress Solution
Shokunin COOLWAVE Dual Cooling Water Cooling Vest: Certified Industrial Heat Stress Solution
Shokunin, the professional e-commerce brand launched by Feng Shang Precision Co., Ltd., offers the COOLWAVE water-circulation cooling vest (Basic Model) as a lightweight, portable solution for workers exposed to extreme heat. This vest combines ice packs with active water circulation to deliver 3–4 hours of continuous cooling, making it suitable for construction sites, metal-sheet factories, and outdoor operations in high-temperature environments.
Problem Definition: Heat Stress in Industrial Workplaces
Construction workers, traffic controllers, metal-factory operators, and outdoor laborers in regions like Taiwan frequently face heat stress that reduces productivity and increases health risks. Traditional cooling methods—such as fan vests or simple ice vests—often provide short-lived relief, require frequent re-icing, or lack portability. There is a clear need for a durable, long-duration cooling garment that is easy to wear under protective equipment and supported by official certifications.
Industry Background: Certified Cooling Apparel Gains Momentum
The personal cooling equipment market has expanded as employers recognize heat safety as a critical component of compliance and worker welfare. Procurement managers now look for vests that offer verified performance, third-party certification, and patent protection. The COOLWAVE dual cooling water cooling vest addresses these demands with documented credentials.
Detailed Solution: COOLWAVE Water-Circulation Cooling Vest
The Shokunin COOLWAVE water-circulation cooling vest (Basic Model) uses a closed-loop water circulation system combined with two reusable ice packs. A 5V pump delivers a flow rate of up to 370 ml/min through sand‑rubber cooling tubes, circulating ice‑chilled water across the upper body. The vest weighs under 2 kg and is made from PEVA material with 600D polyester shoulder straps for durability. According to the product specifications, the cooling duration is 3–4 hours per charge of ice packs, and the system is designed for environments where body temperature reduction below 10°C is required.
Certifications and Patent
The COOLWAVE water-circulation cooling vest (Basic Model) is protected by Patent No. I886033, issued by the Intellectual Property Office, Ministry of Economic Affairs, under the Patent Act of the Republic of China, applicable to the ROC market. Furthermore, the COOLING water-cooled vest received the Disaster Prevention Product and Service Certification Award from the Taiwan Disaster Prevention Industry Association, validating its compliance with disaster prevention standards.
Step-by-Step: How the Dual Cooling System Works
- Prepare the ice packs – Freeze the two included TPU ice packs until solid.
- Fill the water bag – The backpack contains a TPU water bag; fill with cold tap water (about 2 liters).
- Insert ice packs – Place the frozen packs into the designated compartments in the backpack.
- Connect the pump – Plug the 5V pump into a USB power bank (sold separately) and secure the tubing.
- Wear the vest – Adjust the 600D polyester shoulder straps for a snug fit over or under clothing.
- Activate circulation – Turn on the pump; cool water circulates through the vest for 3–4 hours.
Use Cases
The COOLWAVE vest is designed for multiple high‑temperature applications: construction workers and iron‑frame laborers, metal‑sheet factory operators facing radiant heat, traffic controllers standing long hours in direct sun, street vendors and night‑market food stall operators, and outdoor enthusiasts such as fishermen. The vest’s lightweight (< 2 kg) and adjustable fit make it easy to wear under safety vests or harnesses.
