Glacial Precipitator

Glacial precipitator

Have a snowball fight!

A glacial precipitator, or precipitator for short, is a machine that freezes water into snow, ice and similar items.


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



When placed, a glacial precipitator faces the player. It can face any of the four cardinal directions, and can be rotated using a crescent hammer or similar.


A glacial precipitator can be configured to produce snowballs, snow or ice. When its input tank is filled with water, the machine will start consuming Redstone Flux to produce the chosen item. Every produced item requires a certain amount of energy and water. When enough energy has been consumed for an item, the required amount of water is consumed and the output is placed in the output slot.

The amount of water and energy required depends on the chosen output:

Output Water Energy
Snowball x4 500 mB 800 RF
Snow 500 mB 800 RF
Ice 1000 mB 1600 RF

The speed at which a glacial precipitator produces items 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 precipitator 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 glacial precipitator through its sides. Every side of a precipitator may correspond to its input tank, its output slot, or both at the same time.

A glacial precipitator can automatically transfer items out of any sides that directly correspond to its output slot. This is called auto-output, and occurs whenever the machine finishes processing an item, or every 32 ticks (1.6 seconds) if the machine is inactive.

A basic glacial precipitator can automatically output up to 8 items at a time. This amount 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 glacial precipitator may be configured to respond to redstone signals. It can be in one of three modes:

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

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

When a glacial precipitator must stop working due to a redstone signal and is still producing an item, it will finish producing that item before stopping.


A glacial precipitator can have a signalum security lock installed to restrict who can access it.


A glacial precipitator’s configuration can be saved on a redprint to be copied to other precipitators.


Glacial precipitators come in six tiers.

Tier Max. power usage Augment slots Max. items per auto-output
Basic 20 RF/t 0 8
Hardened 30 RF/t 1 16
Reinforced 40 RF/t 2 28
Signalum 50 RF/t 3 44
Resonant / Creative 60 RF/t 4 64


A glacial precipitator 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 precipitator cannot be augmented.

Augments can be installed in the Augmentation tab in a precipitator’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.
Flurry Stratum Flurry Stratum Glacial Precipitator A specialization that allows for a glacial precipitator to produce two snow layers instead of one snow block.
Permafrost Compressor Permafrost Compressor Glacial Precipitator A specialization that allows for a glacial precipitator to produce packed ice instead of ice.
