The Holos Quad is a mobile, scalable micro-reactor (often categorized with micro-sized small modular reactors). It is a thermal gas-cooled microreactor / SMR with electrical output ranging from 3 MWe to 13 MWe for a single Quad unit, scaling up to 81 MWe (Holos Titan) by coupling multiple containers with smaller (Holos Mono) 3–5 MWe versions designed to be airlift-deployable.
