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.
Detail Description
The 300 kW system is our entry-level 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.
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.
Output: 300 kW
Cooling capacity: 300 kW
Expander efficiency：≥86%
Turbine speed：40000 rpm
Inlet pressure: Under 10 MPa Modular & scalable design
Fully automated control
All capacity tiers support optional cold-energy configurations. For the 300 kW unit, typical applications include:
Ice production: Small-scale block-ice plants for local cold-chain markets
Industrial cooling: Direct cold-water loops for nearby factories or process plants
District cooling: Connection to metro-station or commercial-building AC systems
Selection depends on site conditions, local cold-demand profile, and revenue targets.
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.
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.
