Thermal purifier

From Reach

The thermal purifier is a high tech version of an air conditioner. Normal air conditioning units take outside air, cool it, and inject it into a system. Due to the dangerous nature of Reach air, this is inadvisable. The thermal purifier, however, works in reverse. It takes the hot air in a closed system and expels it, work as a physical version of Maxwell's Demon. This device is a critical part of All weather gear, and larger units are in place in the more well off (or closer to the equator) colonies.
