Mekanism: Heated

Machines in the mod start working once the temperature of their heat input passes 300K, and they reach full speed near 1000K, scaling in between. A temperature-controlled smelter processes items only inside a set range, and it can alloy two melted metals automatically inside the machine. Smelting takes 100 ticks per item, which is twice the speed of a vanilla furnace. The smelter can be formed into larger 2x2x2 to 6x6x6 versions, similar to jumbo furnaces, and it supports four recipe types, including liquid input.

A fractionation tower works like an evaporation tower with distillation trays: each compartment outputs to a tank, except the lowest one, which takes input. Below 85K it passively generates liquid nitrogen, liquid oxygen, liquid air and remnant. A pressurized reaction chamber holds up to 16 chemical types and 16 fluid types, accepts items alongside them, and runs full recipes at a controlled temperature. A block beside a creative heat source is available only in creative mode and sets any temperature.

Mekanism: Heated is open source under the GNU General Public License v3.0 or later. It requires Mekanism and is published for NeoForge on 1.21.1 – 1.21.11. The mod is still in early development, and the author expects more updates.
