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 crescent hammer. 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 crescent hammer or similar.


When a fractionating still’s input tank is filled with a fluid, the machine will start consuming Redstone Flux to process it. A certain amount of fluid requires a certain amount of energy to process. When enough energy has been consumed for an amount of fluid, this amount 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 for fluids occurs whenever there is a fluid in the output tank. Auto-output for items occurs whenever the machine finishes processing an amount of fluid, or every 32 ticks (1.6 seconds) if the machine is inactive.

A basic fractionating still can automatically output fluids at a maximum rate of 100 mB/t, and can automatically output up to 8 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 an amount of fluid, it will finish processing that amount of fluid 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 six tiers.

Tier Max. power usage Augment slots Max. fluid auto-output rate Max. items per auto-output
Basic 20 RF/t 0 100 mB/t 8
Hardened 30 RF/t 1 300 mB/t 16
Reinforced 40 RF/t 2 600 mB/t 28
Signalum 50 RF/t 3 1000 mB/t 44
Resonant / Creative 60 RF/t 4 1500 mB/t 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.
