Energy Converter

This Energy Converter, a closed cycle vapor turbogenerator, is a fully integrated, tested and certified power system developed for remote unattended applications. It consists of a combustion system, a vapor generator, a turbo-alternator, an air-cooled condenser, a recifier, alarms and controls housed in a shelter. It is designed to supply 200 to 3,000 Watt of filtered DC power on a continuous, 24 hour-per-day basis for periods of up to 20 years with virtually no maintenance or repairs.

The concept utilizes a hermetically sealed Rankine cycle generating set that contains only one smoothly rotating part – the shaft on which the turbine wheel and the brushless alternator rotor mounted. The turbo-alternator shaft is supported by working fluid film bearings, which eliminate metal-to-metal contact. It can also be run with different heat sources since the fluid cycle is closed and requires only the application of external heat. For continuous maintenance free applications, natural gas is typically chosen. For onshore applications, other fuels such as liquefied petroleum gas, kerosene, jet and diesel fuel are commonly used.
Additional features include:

•Field proven and CE certified
•Digital control compatible with SCADA protocols
•ISO-9001 and ISO-14001 certified
