How the eutectic plates and the gels cool?

Cooling occurs by using a freezer. The residence time of the eutectic plates and or of the gel in the freezer must be at least 12 hours. The eutectic plates with operating temperature -21°C must be "activated" in the freezer at a temperature of at least -28°C, while the other products, both the plates with operating temperature at -12°C and the gels, are activated at a freezing temperature of at least - 20°C. (This piece of information is essential because there is a bit of confusion among customers who use them, especially between -12°C and -21°C plates)
