Great approach to increasing energy efficiency and sustainable reduction of CO2 emissions!
So-called compressed air heat/heat power plants combine two essential energy systems in industrial manufacturing processes: The systems for heating halls and products in production and those for generating compressed air. Why invest twice in investment and operating costs if it also works with one system?
The technical solution is basically as ingenious as it is simple: A combustion engine fired with natural, bio or liquid gas is connected to a liquid-lubricated screw compressor stage via a direct drive.
The result: Almost the entire waste heat of the system, i.e. from the drive motor, its exhaust gas and compressor system, is absorbed and transferred via heat exchangers to the company's own heating or process heat system. This heat no longer has to be produced separately.
The compressed air no longer has to be produced in elaborate separate systems, but is produced as a by-product for heat production - zero (!) kW of electrical current is required! With the sensational result that the oversized cost factor for compressed air generation is completely eliminated.
Compressed air heating power plants are a genuine contribution to the internal cost reduction and for a responsible handling of our nature.
