Tip: —
Experience-based estimate for RimWorld 1.6. Each cooler maintains roughly 100 tiles at ~0°C. Add 1 spare cooler for safety. Walls, insulation and double-doors improve efficiency.
Why Cooler Count Matters
Too few coolers means food rots in summer; too many wastes power. Wall insulation, double doors and a small airlock let each cooler do more work, so you need fewer.
RimWorld Freezer FAQ
How many coolers for a 200-tile freezer?
At 0°C in a temperate biome, roughly 2 coolers with a safety spare. Hot biomes need more.
Should I set coolers to -10°C?
Only for meat-heavy stockpiles. 0°C preserves most food; -10°C needs more coolers and power.
