Keeping cool
Working with a leading manufacturer of industrial heating systems to develop a large, multi-compartment Ex p panel.
Project brief
-
The client required a very large purged and pressurised enclosure to contain the control systems and thyristors for a large heating application in a hazardous area.
Challenges:
- Design and construct a large multi-compartment Ex p enclosure suitable for a wide operating temperature range of -20 to +70oC
- Bespoke door-mounting arrangement required for client’s certified buttons and lamps.
- Thyristors have a high heat output, so a special cooling solution was required.
- IECEx certification was required for zone 2
Outcome:
- A heavy-duty, 4 door enclosure, with a custom internally mounted X-purge system for elevated external temperature operation
- Certified internal anti-frost heating for low temperature system starts
- Special non-gland cable transit system
- An IECEx approved air conditioning unit installed to remove the high internal heat load
- Certification: IECEx
