Unlock Early Game Metal Production with the Smelter Mod for Oxygen Not Included

Tired of waiting for advanced research to unlock essential metalworking capabilities in Oxygen Not Included? The Smelter mod introduces a powerful new building that lets you get a head start on refining crucial materials without the reliance on electricity, making it a perfect fit for your early-game colonies.

Introducing the Smelter

This innovative building provides a much-needed solution for early-game metal production. It bypasses the need for power grids, instead utilizing Refined Carbon as its fuel source. This makes it an accessible and efficient option for any colony looking to expand its infrastructure and crafting potential from the outset.

Key Features of the Smelter:

  • Requires the “Brute-Force Refinement” research to unlock.
  • Utilizes a combination of Metal Ore and Raw Mineral as primary inputs.
  • Requires a Liquid Intake Pipe for coolant management.
  • Consumes Refined Carbon efficiently as fuel.
  • Produces a small amount of Carbon Dioxide as a byproduct.
  • Generates a manageable amount of heat during operation.
  • Boasts a base overheat temperature of 125°C.

The Smelter can process all the same recipes as the standard Metal Refinery and Glass Forge. However, for balanced gameplay, the smelting times for Glass and Steel have been slightly increased by 30%.

Innovative Coolant Management

A standout feature of the Smelter is its intelligent coolant system. It reuses waste coolant until it reaches a critical temperature, optimizing resource usage. When the coolant becomes too hot, you have two distinct options:

  • Normal Mode: Duplicants will bottle the hot coolant, which can then be repurposed for various tasks, such as powering the Microbe Musher or Super Computer.
  • Overheat Mode: The overheated coolant will be directly evaporated into the atmosphere. This can be a strategic advantage for generating Steam or even Petroleum from crude oil.

You can easily switch between these modes using the “Allow Overheating” checkbox, tailoring the Smelter’s operation to your colony’s specific needs.

New Crafting Opportunities

Beyond its core functionality, the Smelter mod introduces exciting new recipes to enhance resource utilization and unlock new crafting paths:

  • A recipe combining Abyssalite, Salt, and Phosphorus to produce Tungsten, Igneous Rock, and Chlorine, offering a valuable use for otherwise difficult-to-process materials.
  • A method to convert Phosphorite directly into Phosphorus, essential for advanced technologies and unique crafting applications like liquid airlocks and natural tiles.
  • (DLC Required) A recipe to efficiently convert Resin into Isoresin and Water.

All gaseous byproducts from these recipes are released into the atmosphere, so plan your ventilation accordingly! The mod also offers extensive configuration options, allowing you to enable or disable specific recipes and even apply some of its coolant features to the vanilla Metal Refinery.
