The Macna Hybrid cooling vest can be equipped with the Cool Pack cooling technology, with renewable biobased Phase Change Material (PCM), Macna uses materials of vegetable origin. Our biobased PCM is non-toxic, 100% biodegradable, low-flammable,
durable, reusable, 20% lighter than water and produces no condensation.
The time required to fully activate the PCM cooling inserts depends on
the Cool Pack temperature and your cooling method:
- Ice water: about 20 minutes
- Freezer: about 40 minutes
- Fridge: about 60 minutes
You can also activate the PCM inserts by exposing them to one
ambient temperature lower than:
- 19 ° C for the Cool Pack 21 ° C insert
Which cooling method you choose, you can shorten the activation time by not stacking the inserts, but laying them flat in a single layer. If you use the inserts directly from the freezer, they may feel too cold to wear. We therefore recommend waiting at least five minutes so that the inserts can warm up to their set temperature of 21 ° C. As soon as the PCM has reached this temperature, it will hold for hours.
Inserts that are activated in a refrigerator or in cold water can be used immediately. Activated inserts can be stored in a cooler or cooler to keep them cold. This way they remain ready for use for twelve hours. If you want to keep PCM inserts in a cooler and / or cooler, you can best activate them in a freezer.
You can store the inserts in your freezer or refrigerator so that they are always ready for use. If you want to leave room in your freezer for something else, you can also store it at room temperature. Lay the inserts flat in a single layer; do not stack them up. If you place inserts in a freezer, make sure they are dry so that they do not stick to the inside of your freezer.
