Compression Dynamo

Compression dynamo

A compression dynamo is a dynamo fueled by fluid fuel and coolant.


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



When placed, a compression dynamo faces up. When placed while sneaking, it faces away from the player. A compression dynamo can face any direction, and can be rotated using a wrench.

Energy generation

When a compression dynamo is filled with fluid fuel and coolant, it will start consuming both to generate Redstone Flux. Fuel and coolant are consumed in batches of 100 mB. Every batch of fuel yields a certain amount of energy when consumed. Every batch of coolant can be used to generate a certain amount of energy; this amount is equal to the thermal capacity of the used coolant.

A compression dynamo generates more energy from the same amount of fuel when stronger coolants are used. The amount of energy generated from each batch of fuel is increased by the coolant factor of the used coolant minus 20% (the coolant factor of water). For example, using a coolant with a coolant factor of 50% increases the amount of energy generated by 30%. The energy increase percentage is added to the energy increase/decrease percentages of any installed augments before being applied to the amount of energy.

The speed at which energy is generated and fuel and coolant are consumed depends on how much power can be emitted, and on the dynamo’s maximum power output. A basic compression dynamo has a maximum power output of 40 RF/t. This can be increased by upgrading the dynamo to a higher tier, and by installing certain augments.

When an active compression dynamo cannot emit the energy it generates, it will keep working at its minimum power output (a tenth of its maximum power output). Any more energy that is generated in this case is lost. This can be resolved by installing an excitation field limiter.

Input and output

A compression dynamo emits Redstone Flux from its coil, which points in the direction the dynamo is facing. It only emits energy when it is active. Fluids can enter a compression dynamo through its sides. They cannot enter it through the coil, unless transmission coil ducting is installed.

Redstone control

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

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

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

When a compression dynamo is deactivated by a redstone signal and is still generating energy from a consumed batch of fuel, it will finish generating energy from that batch first.


A compression dynamo can have a signalum security lock installed to restrict who can access it.


A compression dynamo’s configuration can be saved on a redprint to be copied to other dynamos.

Light source

When a compression dynamo that produces Redstone Flux is active, it emits a light level of 7.


Compression dynamos come in six tiers.

Tier Max. power output Augment slots
Basic 40 RF/t 0
Hardened 60 RF/t 1
Reinforced 80 RF/t 2
Signalum 100 RF/t 3
Resonant / Creative 120 RF/t 4


A compression dynamo 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 dynamo’s tier. A basic compression dynamo cannot be augmented.

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

Augment Installable in Description
Auxiliary Transmission Coil Auxiliary Transmission Coil Any dynamo Increases a dynamo's maximum power output (speed). Can be installed multiple times.
Fuel Catalyzer Fuel Catalyzer Any dynamo Increases the amount of energy a dynamo generates from each unit of fuel. Can be installed multiple times.
Transmission Coil Ducting Transmission Coil Ducting Any dynamo Allows items and fluids to enter a dynamo through its coil, which can normally only emit energy.
Excitation Field Limiter Excitation Field Limiter Any dynamo Lowers the minimum power output of a dynamo to zero, preventing energy loss when it is active and cannot emit the energy it generates.
Boiler Conversion Boiler Conversion Steam Dynamo or
Magmatic Dynamo or
Compression Dynamo
A specialization that changes an applicable dynamo to convert water into steam instead of generating Redstone Flux. This increases fuel efficiency.
Closed-Loop Cooling Closed-Loop Cooling Compression Dynamo A specialization that allows for a compression dynamo to work without consuming coolant. However, at least some coolant must be present in the dynamo for it to work.
Ignition Plugs Ignition Plugs Compression Dynamo A specialization that greatly increases a compression dynamo's maximum power output and the amount of energy it generates from each unit of fuel. However, the dynamo can only generate energy using refined fuel.
Agitative Manifold Agitative Manifold Compression Dynamo A specialization that greatly increases a compression dynamo's maximum power output and the amount of energy it generates from each unit of fuel. However, the dynamo can only generate energy using grassoline.
