Hydrofan

Hydrofan is a manually operated cooling building that a Duplicant can use to temporarily cool a small area nearby. It is meant for localized, on-demand temperature control rather than large-scale refrigeration.

Because its effect is limited to a small area, Hydrofan is most useful for short-term heat management in tight spaces, such as keeping a workstation, hatchery, or other sensitive room from overheating before a more permanent cooling system is available. Its temporary nature makes it a practical stopgap or supplemental tool when precise, local cooling is all that is needed.

• Requires a Duplicant to operate it.
• Cools a small area instead of a whole room or region.
• Best used when heat buildup is minor or intermittent.
• Serves as a temporary solution, not a replacement for dedicated cooling infrastructure.
