InEpact Powerbox ORC

InEpact Powerbox ORC is a power unit that converts electricity from waste or geothermal heat according to the Organic Rankine Cycle principle (ORC).

The entire process is controlled and monitored by a PLC (Programmable Logic Controller), equipped with an operator panel. The PLC controls the process for optimal production of electricity.
It also monitors all components in the system.

General process description of an ORC with a water-cooled condenser

[1-2] The working fluid is preheated and evaporated by a heat source.

[3-4] The pressurized gas expands through the turbine (expander) and the resulting shaft power is transformed into electricity in the generator

[5] Electricity is delivered to the grid through a circuit breaker located in the switchgear.

[8] The working fluid is condensed and re-circulated with a pump.

[9] An operator can manage and supervise the machine from the ORC operator panel.
