## What is Olsberg OEC 4?

Application for automatic combustion control OEC 4.

The OEC 4 automatic combustion control regulates the combustion process itself by means of a microprocessor unit, which results in optimization of combustion depending on the air supply to the combustion chamber by means of an electronically controlled air damper.
