From waste heat to electricity

An ORC turbine (Organic Rankine Cycle) can recover heat from several different sources and convert part of the thermal energy into climate friendly electricity. The result is lower operating costs and a short payback time.

A simple way to reduce operating costs

Since 2013, Againity has developed and installed ORC turbines that convert heat into electricity. The modular ORC turbine can easily be combined with a waste heat recovery unit connected to a diesel engine or gas turbine. This increases the overall efficiency of the system while reducing fuel consumption and operating costs.

In facilities with simple diesel engines or gas turbines, 55–70 percent of the fuel energy is often lost as excess heat in the exhaust gases. Exhaust gas temperatures typically range between 350–550 °C, making them an excellent energy source for Againity’s ORC systems and enabling highly efficient and cost effective electricity generation.

Upgrade your power plant with an ORC turbine

Againity’s ORC systems are delivered in container format and prepared for fast and flexible installation at facilities with gas turbines or diesel engines. The container solution simplifies site preparation and minimises the need for construction work.

Energy efficiency in maritime shipping

By installing Againity’s ORC turbine onboard, excess heat from diesel engines is converted into valuable electricity, increasing energy efficiency and reducing fuel consumption. The result is lower operating costs and reduced emissions without affecting existing operations. The robust design ensures high availability and minimal maintenance, even in demanding marine environments.
