Product Description

Turboexpanders with Advanced Foil Bearings

R&D Dynamics Corporation designs and manufactures high-speed, oil-free turboexpanders equipped with advanced foil air/gas bearings.

Product Models and Power Range:

R&D Dynamics offers two configurations of turboexpanders:

TurboEx (Compressor Loaded): These turboexpanders are typically used to recover energy from gas expansion processes. They are available in a range of sizes from 1 kW to 400 kW.

TurboAlt (Generator Loaded): These turboexpanders are used to generate electricity from the expansion of gases. They are available in a similar power range.

Model sizes range from small (1–7 kW) to larger industrial models (150–400 kW), with gas flow capacities ranging from 200 lbs/hr to 80,000 lbs/hr. These turboexpanders can handle a variety of gases depending on the specific needs of the application.

Key Features and Benefits:

Higher Reliability: Foil bearing turboexpanders have fewer moving parts and require no lubrication, making them more reliable and reducing the need for maintenance. Their reliability has been proven in demanding environments such as aircraft air cycle machines.

High-Speed Operation: The advanced foil bearing design allows turboexpanders to operate at high rotational speeds, achieving greater aerodynamic efficiency and optimal performance.

Compact Size: The ability to operate at high speeds without the need for an external lubrication system enables compact turboexpander designs, saving valuable space in industrial systems.

Environmentally Friendly: Foil bearings are completely oil-free, preventing the risk of contamination of the process gas or surrounding environment. This makes them a sustainable option for industries seeking to reduce their environmental footprint.

No Scheduled Maintenance: Unlike traditional systems, foil bearing turboexpanders do not require lubrication or scheduled maintenance, leading to lower operating costs and reduced downtime.

Wide Temperature Range: Foil bearings are immune to the temperature-related issues that affect conventional lubricated bearings, such as oil breakdown at high temperatures and excessive viscosity at low temperatures.

How Foil Bearings Work:

Foil bearings support the turboexpander's rotating shaft without physical contact. As the shaft rotates, a hydrodynamic film of air or gas is formed between the shaft and bearing surface, lifting the shaft off the bearing. This minimizes friction, enabling the turboexpander to run smoothly at high speeds with no oil or grease required.

Applications:

Turboexpanders with advanced foil bearings are used in a wide range of industries and applications, including:

Air Separation

Oil and Gas Processing

Gas Liquefaction

Power Generation

Cryogenic Refrigeration

Hydrogen Economy

Waste Gas Energy Recovery

Pressure Letdown

Cryogenic Helium Turboexpanders

R&D Dynamics Cryogenic Helium Turboexpanders are designed for efficient and reliable performance in cryogenic helium refrigeration systems. These advanced turbomachines are supported by frictionless foil gas bearings, offering numerous benefits including zero scheduled maintenance, hermetically sealed operation, and high efficiency.

Key features:

No Scheduled Maintenance: The use of foil gas bearings eliminates the need for routine maintenance, reducing downtime and operating costs.

Frictionless Operation: The shaft floats on a hydrodynamic gas film, preventing wear and tear typically associated with mechanical bearings.

Hermetically Sealed: The system is designed to operate in sealed environments, minimizing the risk of contamination and ensuring reliability under extreme conditions.

Integrated Compressor Brake: The turboexpander includes a built-in compressor brake, enhancing operational stability and control.

Waste Heat Exchanger: An integrated heat exchanger is designed to recover and utilize waste heat, improving overall system efficiency.

Speed Control System: The turboexpander includes an integrated speed control system, offering precise regulation of rotational speed, and can be configured for stand-alone or PLC-compatible operation.

Performance Configurations:

High Flow, Low Flow & Low Flow-High Pressure Rise: These different configurations offer flexibility in design and application, ensuring optimal performance across a wide range of operating conditions.

Temperature Range: Suitable for operation within the typical cryogenic helium inlet temperature range of 20K to 80K.

Low Static Heat Leak: Designed to minimize heat loss, ensuring more efficient operation at cryogenic temperatures.
