Special Process Heat Tracing System

The special process heat trace system provides electrical heating where temperature above ambient is required for system operation and freeze protection. 

The special process heat tracing system has no design requirements associated with safety. 

A much better approach to this quantity is possible if special Knudsen cells are used the cover of these has an orifice (10-100 pm) whose size is comparable with the mean free path of a gas molecule. When the system is maintained under high vacuum (p < 0 mm Hg) and constant 7 , the release of the volatiles occurs at a constant rate and the relevant heat flux attains a constant level. Thus both DSC and DTG traces are horizontal straight lines the DSC/DTG ratio gives therefore the vaporization enthalpy at any moment of the weight-loss process [117] ...
