Working with the world’s leading magnetic bearings manufacture to develop a UL compliant hazardous area control system.
Project brief:
- To develop a UL compliant purged & pressurized enclosure for a high-powered magnetic bearing control system
Challenges:
- Create a standardised enclosure design that was suitable for a wide range of low & high-temperature ambient conditions
- Many of the internal components were heavy, requiring complex and precise mounting arrangements
- The core control module had a high heat output when in operation
- The requirement to use all UL approved components to ensure acceptance in the North American market
Outcome:
- A heavy-duty, insulated UL approved 4X enclosure, with a custom internally mounted purge system, suitable for installation with low ambient temperatures
- A UL approved air conditioning unit installed for installations with high ambient temperatures
- Certification: UL
