High-capacity units for major pipeline hubs, gas storage facilities, and petrochemical complexes. Scalable to 10 MW-class per single unit. It houses a radial turbo-expander, speed-reducing gearbox, ex-proof generator, lubrication system, and grid-connection controller on a single skid — delivered, installed, and commissioned as a turnkey module. Supports all downstream coupling options at scale — IDC data centres, hydrogen production, battery swapping, and industrial ice plants.
The unit operates in parallel with the existing throttle-valve branch. In the event of maintenance or shutdown, gas flow automatically redirects to the original pressure-regulation loop with zero interruption to downstream supply.
Detail Description
The 1,000 kW+ unit is designed for large-scale pressure-reduction sites such as main transmission hubs, underground gas storage facilities, and petrochemical plants. For sites requiring MW-level output, multiple units are deployed in parallel, sharing a common control and monitoring platform.
Output: ≥1000 kW
Cooling capacity: ≥1000 kW
Expander efficiency：≥87.5%
Turbine speed：40000 rpm
Inlet pressure: Under 10 MPa Modular & scalable design
Fully automated control
All coupling options are available and scale with the number of deployed modules:
IDC / data-centre cooling: Simultaneous electricity and cold supply — generation powers the facility; −30 °C expander exhaust cools the AC system via heat exchanger, sharply reducing PUE. The throttle-valve branch maintains cold output during generator downtime, so cooling never stops. No fuel, no chiller — just pressure turned into power and cooling.Battery swap + EV
charging: 1 MW powers a 960 kW swap station (8 cabinets); 40 DC fast-charging piles for mixed vehicle fleets also viable.
Green hydrogen: Each 1 MW module can support a 1,000 Nm³/h (5 MW) alkaline electrolyser. Multiple modules enable large-scale H₂ production for industrial or mobility markets.
Combined utilisation: Multiple coupling options can coexist at a single site. A 10 MW hub can integrate IDC + ice + battery swapping simultaneously.
A compact skid-mounted unit for small-to-medium gas pressure-reduction stations. Converts wasted pipeline pressure into 300 kW of clean electricity and industrial-grade cooling — zero additional fuel required. Cold-energy utilisation options (ice production, cold storage, IDC cooling) available on demand.
A mid-range unit for city-gate stations and industrial users. Delivers 500 kW of clean electricity with optional cold-energy monetisation — ice production, cold storage, IDC cooling, or hydrogen production via electrolysis. Multiple revenue streams from one pressure drop.
