Steele Body Cooling Vest - Relief from Heat Stress via Vest Cooling Technology




Types of Passive Body Cooling Vests- The Real Story

Steele Inc. only provides gel ice cooling vests due to the possible flammability/toxicity issues associated with phase change materials. Additionally, as seen below, gel ice provides considerably more cooling that either phase change or evaporative cooling devices.

Cooling Source

Gel-ice: A mixture of starch, water and other ingredients that when frozen, has similar cooling capacity as ice.

Phase Change Material: Paraffin materials that freeze at different temperatures, typically 55 to 65 degrees farenheight.

Evaporative Material: A 3-layer composite fabric designed to evaporate water that is stored in the center layer through wicking.



Feature Benefits
  • Maximum cooling power:
    89.2 watts
    (see test report)
  • Nontoxic
  • Does not leak when melted
  • Proven core temperature reduction
  • Many government test reports available, which prove body cooling capability
  • Can be recharged in icewater
  • Medium cooling power:
    59.5 watts
    (see test report)
  • Cools at a comfortable temperature in non-extreme heat environments
  • Light weight
  • Low profile
  • Inexpensive
  • Light cooling power:
    (see test report)
  • Uses easily available water as cooling source
  • Disposable (1 month use)
Considerations
  • Requires freezing of packs
  • Highly flammable if liquid leaks onto vest from punctured pack
  • Heavy (4-7 lbs.)
  • No data available to affirm core cooling capability
  • Provides only light cooling power
  • Less useful in humid conditions
  • Not effective under protective clothing
