Abstract
With the support of the Defence and Civil Institute of Environmental Medicine, Exotemp Systems Inc. has developed a portable, pocket-sized, catalytic propane burning heat source for personal active heating during cold climate operations. This device heats fluid which can be pumped through the flexible tubing in either off-the-shelf or custom liquid-circulating textile products. There are many potential applications for such a system - heating a survival bag, maintaining the temperature of a medical pannier, actively heated casualty wraps to treat or prevent hypothermia, or even a ration heater. This unit is the first of a family of such devices which will serve as heat sources for liquid-circulating textile products. The heater is only 4.2 x 7.2 x 2.4", weighs approximately 2 lbs and has a heat output of 200 Watts. It can be started in temperatures as low as -30C, but can also be used in colder conditions if the propane is warmed. The impact on defence operations in cold environments may be considerable. The technology may have the most impact in unsupported operations, of 2 to 5 days length, by dismounted individuals or small groups. It will be practical to reduce or eliminate removable passive insulation for winter operations. Sleeping bags and tents may become obsolete for certain missions. Stoves for heating rations and melting snow may be discarded for some missions. TRUNCATED
