Eutectic Systems/Plates
Category: Equipment & Technology
Definition: Refrigeration system using phase-change materials that freeze during off-peak hours and provide cooling during operation through latent heat absorption. Eutectic plates contain a solution engineered to freeze and thaw at specific temperatures, designed for repeated freezing in dedicated charging systems.
How It Works: Eutectic plates are pre-frozen (typically overnight using off-peak electricity). During transport or delivery, the PCM melts, absorbing heat and maintaining cargo temperature for 8-18 hours depending on system size and ambient conditions.
Advantages:
- No moving parts during operation (silent, reliable)
- Lower operating cost (freeze during off-peak electricity rates)
- Consistent at altitude (no performance derate unlike compressor systems)
- Zero emissions during delivery
- High thermal capacity for extended duration
Disadvantages:
- Limited duration (not suitable for long haul)
- Requires access to freezer for recharge
- Higher initial cost than mechanical systems
- Limited temperature pull-down capability
Applications: Last-mile delivery, urban multi-drop distribution, high-altitude operations (Gauteng), insulated roll containers, operations with reliable charging facilities.
