POWER+ Generator — Model: S-ORC 75
Single-engine waste heat recovery and small distributed biomass
Product Overview
Scope’s S-ORC 75 is the family’s distributed waste-heat module, sized for a single low-grade heat source in the 0.6 MWth thermal-input class. The S-ORC 75 employs a two-stage Radial-Inflow Turbine (RIT) expander coupled to a grid-tie generator, with R245fa as the working fluid. The radial-inflow turbine architecture allows for high cycle efficiency across a wide range of inlet thermal conditions. This unit is engineered for retrofit onto a single reciprocating engine, a small biomass boiler, or a single wellhead-class heat source — making it the entry-point for distributed onsite power generation, fleet pilots, and CHP integration where the heat source is one identifiable piece of equipment.

Expander Architecture Note
The Scope S-ORC 75 uses a two-stage radial-inflow turbine (RIT) expander integrated with a grid-tie induction generator on a common skid. R245fa working fluid is chosen for its match to low-to-medium temperature heat sources (90-150°C heat source class) and its established compatibility with HVAC-derived components for ORC service. The cycle operates subcritical, respecting the R245fa critical temperature of 154°C with a typical 19K margin at design point. The RIT architecture is selected for cycle efficiency optimization at this temperature class; reverse-compressor and screw-expander alternatives are available on request for cost-optimized configurations at the smaller sizes (75-500 kWe class).

POWER+ Generator — Model: S-ORC 250
Gas gathering compressor stations and mid-scale industrial process WHR
Product Overview
Scope’s S-ORC 250 targets the mid-scale waste-heat opportunity in the 2 MWth thermal-input class — the size range where a midstream gas gathering compressor station, a paired engine installation, or a mid-sized industrial process makes onsite power generation strongly economic. The S-ORC 250 employs a two-stage Radial-Inflow Turbine (RIT) expander coupled to a grid-tie generator, with R245fa as the working fluid for low-to-medium temperature heat sources. The unit is engineered for stable load-following operation as heat source duty varies through the day, and it pairs naturally with NOV-style centrifuge separation loads in midstream produced-water treatment applications where Scope’s recovered power directly offsets the electrical demand of the water-handling equipment.

POWER+ Generator — Model: S-ORC 500
Mainline compressor stations, refinery process WHR, and geothermal clusters
Product Overview
Scope’s S-ORC 500 is the family’s industrial-process module, sized for a 3.7 MWth thermal-input class which matches the heat duty of a mainline gas compressor station, a small gas turbine WHR application, or a clustered geothermal well group. The S-ORC 500 employs a two-stage Radial-Inflow Turbine (RIT) expander coupled to a grid-tie generator, with R245fa as the working fluid. At this size the economics of waste-heat-to-power become strongly favorable for capital-intensive operations — the unit pays back through electrical offset of plant parasitic loads while reducing thermal discharge to the environment. The S-ORC 500 is also the family’s bridge unit between distributed (sub-MWe) installations and centralized industrial-scale (MWe-class) installations.

Product Overview
Scope’s S-ORC 1000 is the family’s industrial-scale workhorse, sized for a 7.3 MWth thermal-input class which matches the exhaust duty of a typical pipeline-class gas turbine (Solar Mars-class), a large biomass-fired CHP plant, or a midstream water-treatment hub. The S-ORC 1000 employs a two-stage Radial-Inflow Turbine (RIT) expander coupled to a grid-tie generator, with R245fa as the working fluid. At 1 MWe net output, the unit delivers utility-scale economics from a single ORC module — making it the natural choice for projects where a single high-duty heat source needs to be converted to power without the complexity of multi-unit cascades. The S-ORC 1000 also serves as the prime-mover scale for integrated Scope midstream-water-and-power infrastructure stations.

Product Overview
Scope’s S-ORC 3000 targets large-industrial and utility-bridging waste-heat applications at the 21 MWth thermal-input class — installations where a single very-large heat source or an aggregated multi-source manifold makes ORC the right technology choice over conventional steam Rankine.

Expander Architecture Note
The Scope S-ORC 3000 uses a two-stage radial-inflow turbine (RIT) expander integrated with a grid-tie induction generator on a common skid. R245fa working fluid is chosen for its match to low-to-medium temperature heat sources (90-150°C heat source class) and its established compatibility with HVAC-derived components for ORC service. The cycle operates subcritical, respecting the R245fa critical temperature of 154°C with a typical 19K margin at design point. The RIT architecture is selected for cycle efficiency optimization at this temperature class; reverse-compressor and screw-expander alternatives are available on request for cost-optimized configurations at the smaller sizes (75-500 kWe class).

POWER+ Generator — Model: S-ORC 5000
Utility-scale waste heat, integrated midstream complexes, and large geothermal fields
Product Overview
Scope’s S-ORC 5000 is the family’s utility-scale module, sized for a 35 MWth thermal-input class which matches the exhaust duty of a large industrial gas turbine, an integrated midstream-and-water complex, or a large geothermal binary plant. The S-ORC 5000 employs a two-stage Radial-Inflow Turbine (RIT) expander coupled to a grid-tie generator, with R245fa as the working fluid. At 5 MWe net output, the unit competes with conventional small steam Rankine plants on a CAPEX-per-kW basis while offering substantially lower water consumption, faster startup, and unmanned operation. This is the size class where Scope’s integrated platform — heat-to-power + produced water treatment + injection-ready conditioning — operates as full-service midstream infrastructure rather than a single-purpose WHR module.

| Higher Temps or non water/glycol fluids possible with interface heat exchanger | Weight: 140,000 lbs Dimensions: Multi-skid, contact factory (modular ISO containers) | Ambient Temperature Range: 32-104°F (0 – 40°C) |
*Thermal input requirements increase with elevated ambient temperatures / heat sink conditions. **Temperature delta between inlet hot and cold water.
