Fractionating Still

Fractionating still

Products may or may not be drinkable.

A fractionating still (or still for short, also known as a refinery) is a machine that refines fluids.


A placed fractionating still can be instantly picked up by dismantling it with a wrench. Its configuration is preserved in the item. It can also be mined using a pickaxe, though this can be much slower.



A fractionating still is initially at the lowest tier (basic). It can be upgraded to higher tiers using upgrade kits and conversion kits.



When placed, a fractionating still faces the player. It can face any of the four cardinal directions, and can be rotated using a wrench.


When a fractionating still’s input tank is filled with a fluid, the machine will start consuming Redstone Flux to process it. Each batch of fluid requires a certain amount of energy to process. When enough energy has been consumed for a batch of fluid, the fluid is consumed and the output is placed in the output tank. A secondary item output may be produced, which is placed in the secondary output slot.

The speed at which a fractionating still processes fluids depends on how much energy it can use per tick. This in turn depends on how much power is being supplied, and on the machine’s maximum power usage. A basic still has a maximum power usage of 20 RF/t. This can be increased by upgrading the machine to a higher tier, and by installing certain augments.

Input and output

Fluids and items can enter and exit a fractionating still through its sides. Every side of a still may correspond to its input tank, its output tank, its secondary output slot, or certain tanks/slots at the same time.

A fractionating still can automatically transfer fluids or items out of any sides that directly correspond to its output tank or secondary output slot. This is called auto-output. Auto-output occurs whenever the machine finishes processing a batch of fluid, or every 32 ticks (1.6 seconds) if the machine is inactive.

A basic fractionating still can automatically output up to 1,000 mB of fluid and up to 16 items at a time. These amounts can be increased by upgrading the machine to a higher tier.

Which sides correspond to which tanks/slots and whether auto-output is enabled can be configured using the Configuration tab in the machine’s GUI.

Redstone control

A fractionating still may be configured to respond to redstone signals. It can be in one of three modes:

Redstone control is disabled. The still works whenever possible. This is the default mode.
The still works when not powered. When powered, it stops working.
The still only works when powered.

The current mode can be set using the Redstone Control tab in the machine’s GUI.

When a fractionating still must stop working due to a redstone signal and is still processing a batch of fluid, it will finish processing that batch before stopping.


A fractionating still can have a signalum security lock installed to restrict who can access it.


A fractionating still’s configuration can be saved on a redprint to be copied to other stills.


Fractionating stills come in five tiers.

Tier Max. power usage Augment slots Max. fluid per auto-transfer Max. items per auto-transfer
Basic 20 RF/t 0 1,000 mB 16
Hardened 30 RF/t 1 1,000 mB 16
Reinforced 40 RF/t 2 3,000 mB 28
Signalum 50 RF/t 3 6,000 mB 44
Resonant 60 RF/t 4 10,000 mB 64


A fractionating still can have augments installed to improve certain properties or to change how it works. The amount of augments that can be installed depends on the machine’s tier. A basic still cannot be augmented.

Augments can be installed in the Augmentation tab in a still’s GUI.

Augment Installable in Description
Auxiliary Reception Coil Auxiliary Reception Coil Any machine Increases a machine's maximum power usage (speed). However, also increases the amount of energy required per operation. Can be installed multiple times.
Auxiliary Sieve Auxiliary Sieve Machines with
secondary products
Increases the chances of a machine producing a secondary product. However, also increases the amount of energy required per operation. Can be installed multiple times.
Nullification Chamber Nullification Chamber Machines with
secondary products
Destroys excess secondary products when a machine's secondary output slot/tank is full, allowing it to keep working.
Reflux Column Reflux Column Fractionating Still A specialization that increases a fractionating still's conversion efficiency when processing fossil fuels. However, a still can only process fossil fuels when installed.
Alchemical Retort Alchemical Retort Fractionating Still A specialization that allows for a fractionating still to refine fluid potions, increasing their potency level. However, a still can only process potions when installed.
