Ebara Turbine Expanders
The Cryodynamics Division of Ebara International Corporation is proud to introduce our line of single phase and two phase submerged generator turbine expanders. Cryodynamics has developed the world's first site-proven variable speed, liquefied gas turbine expander and most recently, the first variable speed two phase Exducer expander.At EBARA Cryodynamics, we look beyond traditional concepts to find new, innovative ideas that will meet our customer's needs. The development of the variable speed submerged generator cryogenic turbine expander and now the Exducer turbine are both prime examples of our commitment to providing the safest, most reliable products with proven performance for the liquefied gas industry.

The Cryodynamics cryogenic turbine expander is a radial inflow reaction turbine with an induction generator mounted on an integral shaft. The entire unit, including the turbine and generator is totally submerged in the cryogenic fluid. This design approach completely eliminates the need for dynamic seals, shaft couplings, generator support structure and any concern for possible misalignment between the turbine and generator.

By eliminating possible leakage from rotating seals, the design is extremely safe, especially when hazardous fluids are being handled.By using the technology and extensive experience from the proven Cryodynamics pump design, an extremely reliable and efficient turbine has now been developed. The submerged expander includes the same Thrust Equalizing Mechanism (TEM) as used in the pumps in order to balance the axial thrust loads over the operating range. By completely balancing the thrust loads, bearing life is increased dramatically.
