The well-known professional cooling products of  the brand TechKewl have a special method to cool people and animals. You will receive with every cool product the Coolpax, these are separate elements that you place in the freezer or ice water. In a Coolpax is a non-toxic gel that freezes at 14 degrees. After freezing (this takes about 35-40 minutes),  you place the Coolpax into the TechKewl product, which is then cooled to 14 degrees Celsius and will maintain that temperature for 2 to 3 hours. These cooling products are therefore suitable for professional use in warm or hot air, for man or animal.
