Yes, but to get the panels truly hard, the freezer must maintain a temperature lower than -30°C. Otherwise, the panel will be at the temperature of the freezer (in a liquid state) and just won’t last as long.
FAQ Category: Cool Cube™ FAQ
Can a regular refrigerator be used to prep and store refrigerated panels?
Yes, for Cool Cubes™ at Fridge Temps. Make sure the refrigerator temperature is below 4°C to ensure panels turn solid (the closer the fridge is to 4.5°C, the longer it will take to turn solid).
Can a regular freezer be used to prep refrigerator temperature panels and store panels?
Yes, for Cool Cubes™ at Fridge Temps. However, before pack-out, the panels must sit out and warm up until they “sweat” so that they don’t make the cooler too cold.
Why are the Lab Freezer temperature panels not turning solid?
The PCM inside is NOT below its phase change temperature of -21.5°C/-6.7°F. Make sure that the freezer temperature is always below -30°C/-9.4°F.
Why are the Fridge Temperature panels (PCM) not turning solid?
The PCM inside is NOT below its phase change temperature of 4.5°C/40.1°F. Make sure that the storage temperature is always below 4°C/39.2°F.
