Description

The Coolant Cell is an IndustrialCraft 2 reactor component that absorbs heat to keep a Nuclear Reactor from overheating and exploding. A basic Coolant Cell stores up to 10,000 heat units, soaking up thermal energy produced by adjacent Uranium Cells and the reactor hull. Unlike a Heat Vent, the Coolant Cell does not dissipate heat on its own — it works as a heat buffer, buying time and pairing with Heat Exchangers and vents that move heat out of fuel rods and into the cells. Players craft the Coolant Cell from IndustrialCraft 2 components and place it directly into the reactor grid next to fuel and cooling parts. When a cell fills past its 10,000-heat limit it starts to overheat, so reactor designs balance the number of Coolant Cells against total heat output. IC2 Experimental also adds larger 30,000 and 60,000 Coolant Cells for high-output builds. The Coolant Cell is a core part of any safe IndustrialCraft 2 nuclear setup, letting engineers run hotter, more powerful reactors without a meltdown.

Java Edition Guide

How to use a Coolant Cell in IndustrialCraft 2

  1. 1

    Craft the Coolant Cell

    Make the Coolant Cell from IndustrialCraft 2 components at a crafting table before building your reactor.

  2. 2

    Open the Nuclear Reactor

    Place and right-click the IndustrialCraft 2 Nuclear Reactor to open its component grid.

  3. 3

    Insert the Coolant Cell

    Put the Coolant Cell into a slot next to Uranium Cells and Heat Vents so it can absorb their heat.

  4. 4

    Pair it with Heat Vents

    Add Heat Vents or Heat Exchangers so heat moves out of the cell instead of staying trapped at 10,000.

  5. 5

    Monitor reactor heat

    Watch the reactor temperature and rearrange cells before they exceed their 10,000-heat capacity.

Important

A Coolant Cell only stores heat — it cannot remove heat by itself, so always combine it with Heat Vents or Heat Exchangers.

Frequently asked questions

What does a Coolant Cell do in IndustrialCraft 2?

It absorbs and stores up to 10,000 heat inside a Nuclear Reactor, helping prevent the reactor from overheating and exploding.

Does a Coolant Cell remove heat by itself?

No. A Coolant Cell only buffers heat. You need Heat Vents or Heat Exchangers to actually move heat out of the cell.

How much heat does a Coolant Cell hold?

A basic Coolant Cell holds up to 10,000 heat. IC2 Experimental also adds 30,000 and 60,000 Coolant Cells for larger reactors.

Where do you put a Coolant Cell?

Place it in the Nuclear Reactor grid next to Uranium Cells and heat-managing parts so it can soak up their heat.

What happens when a Coolant Cell is full?

Once it passes 10,000 heat it begins to overheat, which is why reactors pair cells with vents to keep them cool.
