Select the driver for your energy profile

The same compressor operates under very different boundaries depending on your energy mix — the right driver matters more than peak efficiency alone.

Motor-Driven

For projects with stable electricity pricing and low-carbon goals. Clear control boundaries; easy integration with renewable power and digital energy management.

Applications
New ASU builds, stable load, renewable power substitution
Advantages
High efficiency, low carbon, simple maintenance

Steam-Driven

For sites with reliable, high-quality steam — convert existing steam directly into compressor drive power.

Applications
Steam-rich industrial parks, chemical processes, stable heat sources
Advantages
Leverage existing steam; reduce grid-side load
Decarbonization compliance pick

Steam-to-Motor Conversion

For decarbonization compliance and lower operating cost — convert legacy steam turbine drives to motor-driven operation.

Applications
Legacy unit decarbonization, rising steam cost
Advantages
Significant carbon reduction; more predictable operating cost
Maximum energy utilization

Steam-Motor Dual Drive

For surplus, variable, or lower-grade steam. Steam turbine and motor/generator work together — compression, consumption, and generation under one dispatch strategy.

Applications
Complex energy mix, large-scale ASU, waste energy recovery
Advantages
Maximum energy utilization; power generation feedback

Triple-drive integration · one train, three energy loops.

In process applications such as PTA, steam turbine, motor, and tail-gas expander can jointly serve one integrally geared compressor — steam, electric power, and residual pressure recovery within a single system boundary.

Steam turbine

Process steam provides primary drive

Motor

Supplementary drive, regulation, and control

Tail-Gas Expander

Recover residual pressure and heat; lower overall energy use
