PCM 4-Cell Cooling Insert
4-Cell Cooling Insert for PCM Vests | High Capacity Cooling Solution

4-Cell PCM Cooling Insert
In cooling vest systems, different insert configurations are designed to meet varying performance priorities. The 4-Cell Cooling Insert is developed to deliver higher cooling capacity and extended performance, making it suitable for demanding environments where stronger heat absorption is required.
Weight: 450g
Size(mm): 345 x 155 x 15
Higher PCM Capacity for Increased Cooling Output
Compared to multi-cell configurations with smaller distributed segments, the 4-cell design uses larger PCM sections.
This allows for increased thermal capacity, enabling the insert to absorb more heat over time.
As a result, it is particularly effective in environments with higher heat exposure or where sustained cooling performance is critical.
Designed for Extended Cooling Duration
- Due to its higher material volume, the 4-cell insert can provide a longer cooling duration under comparable conditions. This makes it a practical option for:
- Long working shifts
- High ambient temperature environments
- Applications requiring fewer replacement cycles
- While the exact duration depends on usage conditions, the design focuses on maximizing cooling endurance.
Structured for Performance Rather Than Weight Reduction
Unlike lighter insert configurations, the 4-cell insert prioritizes cooling capacity over weight reduction. With an approximate weight of 450g, it offers a more substantial cooling presence.
This makes it better suited for scenarios where cooling performance is the primary concern, rather than lightweight mobility.
Stable Cooling with PCM Technology
- The insert uses phase change material to regulate temperature and provide a controlled cooling effect. Instead of delivering an intense cold sensation, it maintains a stable cooling range that supports longer, more consistent use.
- This is particularly important in professional environments where reliability is essential.
Compatible with Cooling Vest Systems
The 4-cell insert is designed to integrate with PCM cooling vest carriers as part of a modular system. It can be selected based on performance needs and combined with other insert options for different use scenarios.
Key Benefits
- Higher PCM capacity for stronger cooling performance
- Extended cooling duration under demanding conditions

- How To Use?
- ①Pre-cooling Preparation: Before use, place the cooling inserts in a freezer for 4 hours to ensure complete freezing;
- ②Placement Method: Simply slide them into the inner pockets of the vest.
- ③Reuse: After use, wait for the cold storage bag to thaw naturally, wipe off surface stains, and it can be reused after re-freezing.
