High temperature process heat at very low pressure.

FTN systems operate in indirect closed-loop mode, allowing high operating temperatures with very low system pressure. Depending on the selected fluid and engineering scope, applications can reach up to 320 C with organic oils and up to 427 C with selected synthetic fluids.
