The Kotach-class resource processor is a structure present on Klingon colonies. These buildings gather the raw materials and convert them into more useful compounds. These processed goods are used for the construction of the colony itself as well as export to the other parts of the Klingon Empire. The processor takes gas, solids and liquids where it refines them into the necessary materials. While an adaptable design, it suffers from the fact that it needs to be recalibrated every time mining commences. Additional wings to the processor are later added to improve the efficiency of the structure. (TOS video game: New Worlds)
