Compact Hetonite (half efficiency)

Requires cuprium, so you'll need to refine cuprium ore elsewhere and store it in your depot. The first set of chained reactor crucibles requires 1u/s of acid (single pump's worth), whereas the reactor beside the purification unit requires only 0.5u/s. You can supply 1 full pump's worth as well as there's no risk of clogging the reactor itself. This is only half efficiency because to run Hetonite at 100% efficiency requires 240u/s of cuprium, which is kind of overkill as we're currently limited to 180u/s cuprium ore with all the current nodes. If you want hetonite parts, just chain a fitting unit between the protocol stash. If you want a full efficiency blueprint however, I've made one here https://talospioneers.com/en/blueprints/01kpkqhw48ft9p0ykgds8gm3n1
