GEPT-R290 phase change unit
R290 compressor to API 619 standard, overall explosion-proof unit design, falling-film evaporator — replaces cryogenic brine in chemical process cooling.
Specification
Energy & Chemical
Oil, Gas & Chemical Refrigeration Unit
Oil, gas and chemical refrigeration units: cryogenic compressors to −271 °C, pressure-direct-expansion generators at 50–1,250 kW, and explosion-proof R290/CO2 cooling for process service.
Cryogenic
Helium Compressor Unit
Jointly developed with Xi’an Jiaotong University, the helium screw compressor runs cryogenic refrigeration as low as −271 °C and supports a large low-temperature system from liquid helium to superfluid helium temperature zone for the Chinese Academy of Sciences — at an internationally advanced technical level.

Pressure letdown, monetized
Oil Injection Screw Expander
Where natural gas is decompressed at city stations, pipelines and wellheads, pressure energy is normally vented to the atmosphere. The screw expander converts it into 50–1,250 kW of electric power, with by-product cold energy available down to −50 °C.
- Inlet −40 ~ 200 °C · 0.4–5.0 MPa · max expansion ratio 20 per machine
- Flow 285–48,000 Nm³/h · expander efficiency 60–85%
- MSHE-12S~32S series: 3,400–38,400 Nm³/h at 40/16 bar(g), generating 50–646 kW
- Stable operation through inlet pressure and flow fluctuation; no special on-duty personnel
Process cooling
Chemical process duty, explosion-proof design
Relaxation pressure service
The screw expander also covers chemical plant relaxation pressure, process gas flash evaporation decompression and wellhead pressure letdown.
