The secret of the turtle
A new orientation
The company Truma Gerätetechnik GmbH & Co. KG in Putzbrunn near Munich was also alerted to the high-performance Turtle Blower. The market leader in the field of liquid gas heating systems for leisure vehicles and boats has developed a fuel cell that can be operated with a conventional propane gas bottle. Because the cell uses hydrogen as fuel, the propane gas first has to be converted in a so-called reformer. The portable VeGa fuel cell system simultaneously employs the blower for two different tasks.
In the reformer, the Turtle Blower supplies the catalytic burners which provide the required temperature for the reforming process. In the fuel cell, the blower conveys the oxygen from the ambient air to the cathode, also under high pressure. The Turtle Blower performs both tasks controlled by valves. Although the standard CPAP centrifugal blower already generates a high pressure with 20 millibars, the engineers at St. Georgen had to modify the coils of the drive motor for Truma, as a higher operating point was needed. The blower now generates an operating pressure of up to 45 millibars in this application. And that is not the only thing that makes it a truly powerful universal genius.
