Competitive advantage

  • Current self-cooling vests are heavy, expensive and either require a substantial power source or must be refrozen, limiting their useful operating time
  • Our system is lightweight and cost-effective. It uses no power source and can operate indefinitely
  • The system is based on a thermosiphon process. It uses a low boiling point phase change material (LBPCM) with a refrigeration cycle and circulation of helium


  • Reduced heat stress in military personnel
