The vast majority of refrigerated vehicles on the market employ vapour compression refrigeration systems, operating from the vehicle’s engine or from an auxiliary diesel engine. In today’s business environment, where fleets in major cities are facing stricter regulations regarding vehicle emissions, one must look for alternatives to conventional diesel-powered transport refrigeration units. Eutectic refrigeration might be the answer.
Eutectic systems consist of hollow tubes, beams or plates filled with an eutectic brine to store energy and produce a cooling effect whenever necessary to maintain the correct temperature in the refrigerated container. Eutectic system is suitable for long distance distributions as well as door-to-door deliveries and is ideal for an operation with multiple stops and door openings.
How does eutectic refrigeration work?
The operating principle of the eutectic refrigeration system is just as simple as it is efficient. Unlike conventional systems, eutectic refrigeration uses cold source provided by an eutectic solution instead of direct expansion of refrigerant gas. The eutectic plates or beams are charged at night on mains power using off-peak electricity. They store the cold energy and gradually release it in the form of cold air, thus refrigerating the area around.
Refrigerated body with eutectic system is completely independent from the chassis, therefore stable temperature is ensured at all times. Once the eutectic plates are charged, they provide a reliable, rapid cooling for a specific duration of time even with frequent door openings. Merchandise is preserved in case of vehicle failure.
Eutectic system also does not use diesel, making refrigerated bodies with eutectic cooling an eco-friendly alternative, compatible both with electric trucks and internal combustion engines. Due to zero emissions and an absence of engine noise, such refrigerated trucks are ideal for multi-drop operations, especially in urban areas.
- Zero-noise operation
