TechNiche Coolpax Cooling Inserts With Extended Duration are safe, effective and comfortable. Coolpax Cooling Inserts maintains a comfortable 58F (14C) for up to 4 hours. They use additional inserts for continuous relief. Phase Change Material releases long-lasting, temperature-specific cooling relief. Provides cooling comfort and heat stress protection in high-temperature environments. Commonly used in extreme heat under work gear, costumes, and other apparel.
CoolPax is our Phase Change Material (PCM) cooling technology. It uses a non-toxic carbon-based liquid that freezes at 58F/14°C and remains at that temperature for 2-3 hours. Simply place CoolPax inserts in freezer or ice water for 35/40 minutes and insert into garment pockets. Science Behind CoolPax- A Phase Change Material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa; thus, PCMs are classified as Latent Heat Storage (LHS) units.
