Expanders

Cryostar

We are a proud distributor of Cryostar!  Please find their expanders line up below:

ECO Expander

ECO

With Oil Brake

Oil Brake loaded Expanders designed for low pressure applications up to 80kW. Introduced by CRYOSTAR in the early ‘80s and available with three wheel sizes (70, 90 and 120mm), the ECO has become a reference recognized for its reliability and competitive price. The standard package consists of the expander assembly with shear oil brake, the lube oil system and the quick closing valve (QCV).

TP Expander

TP

With Oil Brake

Oil Brake loaded Expanders with power capacity from 50 to 300kW.
Intended for nitrogen and oxygen generators, the TP is supplied as a skid-mounted unit to minimize on-site installation work.

TFC Expander

TFC

With Oil Brake

Combination of variable Oil Brake and Compressor loaded Expanders available with five wheel sizes with power capacity up to 2,000kW.

LTP Expander

LTP

With Oil Brake

Oil Brake loaded Liquid Expanders available with two expander wheel sizes (70 and 90kW).
A cryogenic liquid turbine reduces ASU energy consumption by 1.5 to 5%.

TC Expander

TC

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.

MTC compressor loaded expander

MTC

With Compressor Brake

Compressor loaded Expander with active magnetic bearings (no oil system).

TG Expander

TG

With Oil Lubricated Bearings

Generator loaded Expanders with oil lubricated bearings. The energy recovered from the expansion is powering the generator through a gearbox to convert shaft power into electricity that can be sent back to the grid.

The TG is available in nine frame sizes with a power range from 75 to 20,000 kW.
Design is customized to fulfil customers’ requirements in terms of standards: API standards, local standards or customers’ best practice standards can be applied on request.

LTG Expander

LTG

With Oil Lubricated Bearings

Generator loaded Liquid Expanders available with 8 wheel sizes (from 70 to 600mm) with a power range up to 7’000 kW.

A cryogenic liquid turbine reduces ASU energy consumption by 1.5 to 5%

MTG Expander

MTG

With Magnetic Bearings

Generator loaded Expanders with magnetic bearings and high speed generator directly connected to the turbine wheel. High frequency power is converted to grid frequency power via a power conversion system (AC/DC – DC/AC).

This TG is designed for low flow, reduced footprint stations. Maximum power is 300 kW.

MTC compressor loaded expander

MTC

With Magnetic Bearings

Compressor loaded Expander with active magnetic bearings (no oil system). The MTC is available in 5 frame sizes. Maximum power is 12’000 kW.
Design is customized to fulfill customers’ requirements in terms of standards : API standards, local standards or customers’ best practice standards can be applied when requested.
