Expander with Compressor brake



Compressor loaded Expanders with oil lubricated bearings. The expander and compressor wheels are mounted on a common shaft and the energy recovered from the expansion is powering the compressor wheel that can be used as a booster compressor.
A double or triple shaft seal arrangement ensures no lube-oil leakage to the atmosphere or the process gas.

The TC is available with 8 expander wheel sizes (from 120 to 800mm) with a power range from 50 to 12’000 kW.
