What to Buy with Cooling Vests?

How Phase Change Cooling works?

  • Cool PaxTM are made up of phase change material sealed in polyurethane
  • Cool PaxTM inserts solidify in temperatures below 14C
  • Once solid, they cool by absorbing heat away from the body, thus maintaining a temperature of approximately 14C within the vest
  • The vest can be activated in any environment where the temperature is below 14C (freezer, cooler etc)
  • The inserts typically last 2-3 hrs and recharge in 35 mins.
  • No airflow is required, ideal for humid environments or under heavy protective gear
  • Can be stored in the freezer/chilling unit
  • Chemical based cooling using Phase Change Material (PCM)
  • PCM is lighter than water (70% the weight of water)
  • There is no freezer burn, condensation or fluctuating temperatures w/PCM and they last longer than water based vests
  • They are made of 100% Cotton
  • Vests weight approx 5.5lbs
  • PCM inserts can be made into a variety of shapes and sizes
  • Vests come in M/L (100-175lbs), L/XL (175-250lbs) & 2XL (250-300lbs), Custom Increases productivity - Performance
  • Reduces the risk of heat stress & OSHA concerns - Safety
  • Improved employee satisfaction – Comfort

Science Behind CoolPax PCM

A Phase Change Material (PCM) is a substance with a high heat of fusion which, melts and solidifies 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.
