Rini Technologies’ personal Thermal Management System is a vest system which is worn under equipment to maintain a comfortable temperature for the wearer.
It features a system of water-filled tubes which circulates through a Thermal Management Unit, a refrigeration unit that chills the water to a comfortable 72 degrees farenheit. Rini also offers a heater box for colder temperatures, which heats the water to around 100 degrees fahrenheit. These systems are powered either through a separate battery pack, or through vehicle power.
Rini has also developed a variant of the PTMS in a MilSpec desert oriented colorway, as well as a specialized TMU developed in collaboration with PEO Soldier, with a 28 volt system designed to run off aircraft power, for use with US Army Aviation.
