There are many applications for Eutectic Plates. Many goods require a specified minimum temperature during transport. These plates are essentially cool-blocks that are filled with eutectic gel and frozen, and then added to the consignment of goods. In some cases, the plates may be re-used several times. Some manufacturers also manufacture reusable versions. As long as the temperature remains within acceptable limits, they are an excellent choice for any cold chain.
Sensitive Healthcare Products
The ambient temperature of the possible to use eutectic plates can be set to the required range for different purposes. These devices can be used to store temperature-sensitive healthcare products. The temperature range is generally between +2 and +8 degrees Celsius. To test these devices, a corresponding eutectic plate with a mass of 700 g and a mass of 350 g is placed in the middle of the solution. The plates are simultaneously placed and tested. The temperature rise of each plate is recorded over time, and the mean values are displayed below:
- In the study, 8 frozen eutectic plates were stabilized at -20 degC for 48 hours. After stabilisation, they were placed in an insulated container.
- Three sensors were used to monitor the temperature, preventing freezing. During the 88-hour test, the temperature of the products was maintained between -2 and +8 degrees Celsius.
- The test results were positive if the temperature was within the acceptable range.
Number of Eutectic Plates
If the ambient temperature is +18 degrees Celsius, the eutectic plates liquefy and absorb the excess heat. The temperature of the plates is regulated between +15 degC and +25 degrees Celsius, depending on ambient temperature, type of insulated container and number of eutectic plates. The temperature range is not constant and can vary greatly, so it is important to carefully monitor the temperatures.
Central Chamber of Pallet
If a cooling chamber is not available, the eutectic plates are placed in the central chamber of the pallet. The pallet is then stabilized in this temperature for less than 24 hours. The temperature increase time will depend on the size of the pallet and its shape. This method is particularly useful when eutectic plates need to be transported long distances. The temperature increase time for a pallet will vary as it has gaps.
Optimal Temperature
When freezing eutectic plates, it is important to remember that the temperature of the eutectic liquid must be at least 5 degrees below its melting point. To ensure that freezing does not take too long, the plates must be separated at least three centimeters. When the plates are stacked, they cannot circulate cold air, which can significantly increase the freezing time. For optimal results, the eutectic plates must be kept at the optimal temperature for 6 to 24 hours.
Eutectic Refrigeration System
The eutectic refrigeration system operates on a similar principle as a refrigerator in the home. The eutectic plate is charged overnight while the truck is parked, and then slowly releases cold air and energy. The eutectic plates are a great way to preserve merchandise when a vehicle is not working properly. They even serve as a backup in case of emergency.
Oil Pressure Safety Control
Oftentimes, compressors fail because of the eutectic plate or due to loss of proper lubrication. Low pressure controls cause lubrication problems, eutectic solution freezing in the plates, and refrigerant velocity and density to decrease. Oil trapped in the evaporator can also cause the compressor crankcase to empty and trip the oil pressure safety control.

Temperature of Eutectic Solution
The temperature of eutectic solution on ambient thermal storage plates is studied to evaluate its stability. These thermal storage units are often used for heat-sensitive healthcare products to maintain their temperatures between +2 and +8 degC. To prevent their temperature from dropping below +2 degC, these plates are frozen at -20 degC and stabilised at -2 degC by using the latent phase of the eutectic solution.
Final Words:
The temperature of eutectic solution on ambient temperature plates is determined by freezing the solution on both sides of the plate. A true eutectic solution freezes at a specific temperature and remains at that temperature until it is completely melted. This is a crucial parameter in holding plates, as water has a freezing point of 32i? 1/2 F, which is much too low to serve as a holding plate. This temperature difference is especially significant in refrigerators, as below 35i? 1/2 F, food becomes freezer burned.
