The ERPT (Eudosia Remote Power Turbine) is an electrical generation system for remote, unmanned applications, based on the Organic Rankine Cycle. It produces continuous power with minimal maintenance in the most extreme environments, from the Arctic to the hottest deserts and offshore, offering a real alternative to solar and wind solutions.
Overview
Developed by Eudosia Sistemi and protected by patent, the ERPT is an outdoor unit that converts the heat of a gas burner into regulated DC power. A station delivers up to 10 kW, generated to match the actual load demand, with a regulated 48 V DC output (24 V DC on request). It is designed for unattended operation, with an annual visual inspection as the only scheduled maintenance, and for more than 30 years of service with no overhaul and no performance ageing of critical parts. Remote monitoring and control are built in.
How it works
- Combustion: the gas burner heats the organic working fluid in the vapour generator
- Vaporisation: the fluid turns to vapour, under vacuum, below 200 °C and 1 bar
- Turbo-alternator: the vapour drives a turbine coupled to an alternator, generating three-phase power
- Condensation: an air-cooled condenser returns the fluid to the closed loop, and the electric and control system rectifies and regulates the output
Main components
Combustion system (gas supply, burner and exhaust); vapour generator; turbo-alternator; air-cooled condenser; electric and control system; lightweight anti-seismic structural frame sized for a standard container; walk-in shelter housing the combustion and control systems.
Configurations
- Offshore: certified for ATEX Zone 2, Group IIA, T3, with a footprint of less than 12 m² for platforms and barges
- Desert: operates up to +65 °C with a special working fluid mix and boosted cooler fans, in high dust and sand
- Arctic: operates down to −45 °C with a no-freeze mix, dedicated insulation and structural materials rated for the design temperature
- Hybrid: combined with existing power equipment on site
Applications
Power for remote and unmanned industrial sites: gas pipelines and wellheads, offshore platforms, Arctic and desert installations, telecommunication and control equipment in the Oil & Gas and Power Generation sectors. As the original equipment manufacturer, Eudosia Sistemi can adapt the unit to customer requirements and integrate the customer’s own equipment shelter with the ERPT.
Technical data
