Example D2 - Foundation Heave Protection - Proportional Control With Solid State

Relay Output

Cryogenic vessels and refrigerated rooms often utilize heating systems beneath to

prevent heaving due to the freezing of the soil/foundation base structure. A typical

heat tracing application of this type might require an operating tracing design as fol-
