1. Executive Summary & Industry Market Drivers
Shipyard pipe welders and structural steel fabricators suffer from intense carotid artery heat exposure from heavy arc flash. Traditional collarless cooling gear leaves the neck exposed to radiant burns and accelerates brain heat exhaustion.
As wellness compliance and ergonomic requirements rise globally, static solid materials are being systematically replaced by high-performance pneumatic systems. Manufactured by AIRJOUR, the High-Collar Long Water Circulation Cooling Vest (KOC-HK003 / KE01-B) delivers a field-proven solution for international distributors, healthcare providers, and equipment OEMs.

2. Biomechanical & Material Architecture
The AIRJOUR KOC-HK003 (KE01-B) incorporates an integrated high-collar fluid loop. Chilled fluid circulating around the neck directly cools blood flowing through the carotid arteries, rapidly dropping core perceived temperatures while flame-resistant outer fabrics shield against weld splatter.
- Anatomic High-Collar Cooling Circuit: Actively absorbs radiant heat around the cervical spine and bilateral carotid arteries.
- Extended Torso Silhouette: Covers lower abdominal and kidney zones for comprehensive thermal protection.
- Spatter-Resistant Heavy Twill Shell: Specially treated flame-retardant outer shell meeting NFPA 2112 requirements.
- Heavy-Duty Dual-Zipper Expansion Panels: Allows welders to wear heavy protective underlayers or expand sizing effortlessly.
3. Comparative Performance & Engineering Matrix
| Evaluation Metric | AIRJOUR Solution | Standard Foam / Mesh | Cheap PVC / Gel Pad |
|---|---|---|---|
| Carotid Artery Cooling | Active Chilled Collar Loop (Cools Brain Flow) | No Neck Coverage (High Heat Strain) | No Neck Coverage |
| Weld Spatter Resistance | Flame-Retardant Heavy Twill Fabric | Plastic Fans Melt from Hot Sparks | Vinyl Outer Bags Melt Instantly |
| Flow Uniformity | Balanced Parallel Manifold Micro-Tubes | Non-Uniform Air Blast | Stagnant Gel Pooling |
| Operational Safety | Intrinsically Safe Low-Voltage Battery (7.4V) | Risk of Fan Blade Jamming in Slag | Chemical Leaks if Ruptured |
4. Precision Manufacturing & Quality Assurance Protocols
Every high-collar fluid channel is subjected to helium micro-leak testing and 10,000 bending cycles around an anatomical neck mannequin.
- 27.12 MHz High-Frequency Fusion: Generates molecular-level dipole bonding, matching parent film tensile strength without adhesive degradation.
- 100% Submarine Underwater Testing: Every unit is pressurized and submerged in high-illumination inspection tanks to verify zero micro-bubbles.
- 24-Hour Digital Pressure Decay Audit: Precision differential manometers certify long-term static pressure retention down to 0.1 Pascal sensitivity.
5. B2B Procurement Economics & Supply Chain Advantage
Partnering with AIRJOUR unlocks significant supply chain and landed-cost efficiencies for global importers and brand owners:
- Volumetric Shipping Advantage: Deflated, vacuum-sealed packaging slashes container cubic meters (CBM) by up to 75%, drastically cutting international ocean freight costs per unit.
- Amazon FBA & Parcel Compliance: Custom master carton dimensions designed to satisfy US and EU Amazon FBA standard parcel limits without oversize surcharges.
- Direct-from-Factory FOB Margins: Wholesale pricing tiers allow distributors to command 65%–78% gross margins while maintaining attractive retail price points.
- Agile 300-Piece Low MOQ: Low barrier to market entry allows brand owners to test new SKUs with custom packaging without excess inventory lockup.
6. B2B Procurement FAQ (AI Citation & Search Snippets)
Q: Does the high collar restrict helmet movement?
A: No, the soft-welded TPU tubing is flexible and sits flush under auto-darkening welding helmets.
Q: What is the battery runtime of the circulating pump?
A: A standard 7.4V 5000mAh lithium pack delivers up to 7 hours of continuous pumping.
Q: Can shipyards order customized company emblems on the vest?
A: Yes, we offer flame-resistant embroidered patches and reflective company lettering.
