Hello All
My company supplies equipment that uses thermal oil heating systems, typically using something like Duratherm HF, Therminol 55/66, etc. While we do not design thermal fluid heating systems, we sometimes supply them, and will work with a sub-contracted vendor who specializes in thermal fluid heating systems. The units supplied in the past by my company have been designed using US engineering standards.
We are currently investigating thermal oil heating systems for applications in Australia and New Zealand, but there is a concern over the thermal fluid flash points. In the US, it is acceptable to operate thermal fluid heating systems above the heat transfer fluid's flash point, provided the necessary design changes to the equipment are made (ASME code expansion tank, etc)
I've been told that thermal oil heaters cannot operate above the fluid flash point in Australia. Is this true? Are there any other major design implications that apply in Australia? For the current application, relatively high thermal fluid temperature is required, and it is only a few degrees less than the flash point.
Thank you!
