Move towards carbon neutrality and economic efficiency 

In many industrial processes, lots of valuable energy and residual gases can simply go to waste. With the general drive towards carbon neutrality and demands for ever greater economic efficiency, it has become important for industrial machinery to operate with optimal efficiency while maximizing resource utilization. 

Everllence expanders are particularly designed for energy recovery. Turboexpanders utilize excess power or heat to drive separate power generation units or turbomachinery in power recovery trains, thereby achieving maximum efficiency. 

Powerful, carbon-free energy systems by Everllence

We are constantly developing new processes and solutions for a carbon-free future. Our energy storage and heat pump solutions are designed as closed cycles containing compression and expansion of diverse refrigerants and air. Let Everllence be your partner to improve and optimize your processes – ensuring reliable power is delivered when it is needed. 

Depending on your requirements, Everllence expanders come in single and multistage designs and in axial or radial blade/impeller configurations. Our turboexpanders are either connected to a power generator or directly integrated into a compression train.

Range covered:

  • Power output up to 45 MW
  • Inlet temperature up to 760°C (1,400°F)
  • Inlet pressure up to 25 bar

High-performance expanders FAQs

Expanders offer significant benefits in gas processing and energy systems by improving efficiency and reducing overall energy consumption. They allow for effective energy recovery from high-pressure gas streams, which can be converted into useful mechanical or electrical power. This not only lowers operational costs but also supports sustainability goals by minimizing energy waste. Additionally, expanders help in achieving the required cooling in cryogenic systems and enhance the performance of processes such as LNG production, gas liquefaction, and refrigeration cycles. Their robust design and adaptability make them essential components in modern energy and industrial systems.
An expander, also known as an expansion turbine, is a mechanical device used to recover energy from pressurized gases by allowing them to expand and cool while driving a turbine. In industrial applications, expanders are commonly used in cryogenic processes, natural gas processing, and air separation units. As high-pressure gas flows through the expander, it undergoes a drop in pressure and temperature, converting thermal and pressure energy into mechanical energy. This energy can be used to generate electricity or drive compressors and other equipment, making expanders highly efficient for energy recovery and process optimization.
