Eutectic Plates

Passive cooling devices containing phase-change materials that absorb heat as they melt, maintaining stable temperatures without active refrigeration. Pre-frozen plates placed in insulated containers provide hours of cooling, making them suitable for last-mile delivery, small-volume transport, or backup cooling. Unlike active refrigeration, eutectic systems require no power during transport, reducing noise, emissions, and operating costs. However, they require frequent plate replacement and pre-freezing infrastructure. This technology suits urban delivery routes with short distances and frequent depot returns, providing economical cold chain solutions for smaller operators or supplementary capacity for established providers.
