- It makes sense that it would exist. If heating nuggets to get the water out is the first and presumably simplest step of mineral processing, it could be available as standalone equipment.
- It would bridge the large price gap between a bare cargo bay and the very expensive (for a fresh character) first MPU
- It's a perfect fit for the new OCP-209 ship, which has minimal processed mineral storage, but a very large cargo bay, so it's best suited to hauling in ore in unprocessed form. Currently this playstyle is very limited as it means carrying a lot of excess water weight, and giving up on remass recovery.
Naturally to avoid jamming it would need a very large active area, like the Rusatom MPU (maybe it's just the heating and remass collection parts of a Rusatom MPU)
As a bonus distinguishing feature it could have baffles, which would be fitting for its purpose.
