Unique technology for efficient power generation at low temperatures
SRM Powerbox is a modular power unit that converts waste and geothermal heat to electricity from temperatures as low as 55 °C. The output is emission-free power and profit. The unique SRM Powerbox technology makes it is economically viable to generate electricity from waste and geothermal heat sources at low temperatures. Applications include marine & gen-sets, renewable power stations and industry plants like pulp & paper, cement and steel.
Working conditions
- Hot water/oil: temperature range 55 – 160 °C
- Steam: wet, saturated or dry steam ≤ 35 bar (a)
Proven in service
The quality of SRM Powerbox is proven in many successful installations.
SRM Powerbox is enabling its end-users to meet their environmental and energy efficiency commitments, while improving system performance and profitability at the same time.
SRM Powerbox makes a great contribution in energy saving and is a key factor for future safety and protection of our environment.
Continuous development
In parallel, new and more environmentally friendly refrigerants are entering the market, opening for new designs with an optimized performance.
Hence, the design of SRM Powerbox is always state-of-the art, incorporating the latest ideas and features.
SRM Core technology – our expander
The decisive factor for SRM Powerbox is our unique oil-free SRM expander which is used both in our ORC and WST.

Orders & Installations - SRM Powerbox ORC & WST
The first unit was installed already 2008 at a CHP plant in Sweden. The temperature of the heat source was only 65 °C.
Since then, more than 35 units have been installed in various industries, e.g. in Marine vessels, Pulp and paper, Steel/Iron factories, Geothermal, Incineration plant, Chemical Industry, Tyre factory , Biomass CHP.
The heat sources vary from hot water, 65-150 °C, to steam, 2-26 bar(a). The cooling sources include river water, district heating network, cooling tower etc.
The net output varies from 250 – 1600 kWe.
