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)
