The Faretec LifeBox50 is designed for the first responder to transport anything he needs that is temperature sensitive; without having to worry about a heavy, tethered powered unit. The responder is not restrained by temperature changes over time. The LifeBox50 is able to maintain its core temperature for unprecedented durations in the most extreme ambient conditions. The standard box can hold eight 1 Liter IV solutions at temp for over 50 hours. Superior insulation, combined with rugged cases for protection, make it the number one choice for any medic.
