Motor Systems for Low Temperature Applications

As oil & gas extraction has pushed into new, often more extreme environments, both the use and the protection of large motors starts to become problematic. A major motor OEM brought us just such a challenge to develop a motor purge system capable of operating in very low ambient temperatures.
If the instrument air supply is too cold: Where the temperature of the incoming air cannot be maintained, not only is there a risk of damage to equipment, but, critically, the system might be operating outside of its certification limits. Expo can provide users with additional security through a range of certified, in-line air heating units. These systems are specially designed for high flow applications and can be integrated into the overall motor purge installation.

- Certification required
- Ambient temperature limits
- Machine dimensions and internal volume
- Maximum enclosure leakage rate
- Required purge time
- Temperature of instrument air
