ORC

Againity’s in-house developed ORC system enables high quality and short pay-back time

Againitys system is based on the long-known ORC technology (Organic Rankine Cycle), which is illustrated in the image to the right. The technology includes a steam turbine set in motion by the pressure from hot steam. The rotating turbine then drives a generator that produces electricity.

To heat up the steam, some heat source is needed. Any heat with a temperature from 90 degrees Celsius can be utilized in the system. It may be waste heat from a Diesel generator, heat from a boiler that burns pellets, landfill gas or household waste. hot water from solar panels, or waste heat from an industrial process. What kind of waste heat do you have in your business?

The efficiency of the ORC system is dependent on the temperature difference between the system’s hot and cold side. The hot side corresponds to the temperature of heat that enters the system from the connected heat source. The cold side is the medium that the cooling system is connected to. It can be the outdoor air, a river nearby, or tap water for residential buildings, hotels, hospitals or industries. In good conditions, the electrical efficiency is 15%.

Thanks to the unique design of our patent-pending turbine and the low number of moving parts in the system, a high-quality product can be offered. This minimizes the need for service and maintenance and significantly shortens the payback time.
