8.8 Electronic Thermal Management
The Electronic Thermal Management option is only available for specific machine models.
The design of the electronic thermal management (ETM) is determined by your machine's options.
Type
Electronic thermal management (ETM)
Machine type 1
Without heat recovery
Machine type 2
Heat recovery without electrically controlled valve
Machine type 3
Heat recovery with adjustable airend discharge temperature for the
regulator of the electrically controlled heat recovery valve
Tab. 65 Machine type and ETM design
Note:
■ The machine runs with increased airend discharge temperature when heat recover is set to ac‐
tive.
■ An increased airend discharge temperature causes poorer efficiency of the compressed air
generation.
1. Check whether your machine is fitted with electronic thermal management.
2. Check whether the nominal value of the discharge temperature for the regulator of the electri‐
cally controlled heat recovery valve can be adjusted.
3. Activate the heat recovery only if you can use the machine's exhaust heat.
4. Deactivate the heat recovery if you cannot use the machine's exhaust heat.
