An advanced piece of technology originally designed by the Diagnosan Tocot and later seems to be under production by the Peacekeepers. The first example of a cooling suit was worn by Scorpius as a method of as suggested keeping his inter body in particular his brain at a desired temperature. The template for all known cooling suits, Scorpius’ suit has a highly unique property in that it involves a cooling system inserted directly into the brain (this is to accommodate his unique physiology, as his Sebacean/Scarran physiology requires him to be kept at a precise temperature to prevent his Sebacean half entering heat delirium or his Scarren half being immobilised by cold).
The main mechanics of the cooling suit involves the use of a cooling rod fixed to the suit which over time absorbs all excess heat produced by the body keeping it at optimal temperature. The rod will slowly absorb heat to the point that it itself will overheat; meaning in time it must be replaced or removed and allowed to cool in order for the suit to remain functional. This switch must be done on a regular basis or else the suit will fail.
The Cooling rods themselves are composed of a mildly radioactive solution, that, when heated to capacity by the body have been shown in The Peacekeeper Wars to be explosive enough to destroy metals (such as Dorian ore) that a high powered Luxan pulse rifle could not singe.
