The Compression Dynamo is a block added by Thermal Expansion 4. It is used to generate Redstone Flux (RF).



The Compression Dynamo uses a liquid fuel and a coolant to produce RF at a maximum rate of 80RF per tick without augments. It will not produce energy if either tank is empty and will reduce the rate depending on how full the internal storage is unless it has a excitation field limiter installed.

To change the orientation of the dynamo, use a Crescent Hammer.
