A shell and tube heat exchanger, on this work order, is looked at from the outside. Pulling a channel cover or rodding tubes is a different, permitted job.
ChatterFix builds these as child assets under shell and tube heat exchanger, so failure history and PM completions attach to the component that actually failed — not just to the machine.
The failure modes worth designing a maintenance schedule around — in rough order of what they cost when they happen.
Recording that a PM was "done" tells you nothing next quarter. These are the readings that let you see a failure coming — and the reason ChatterFix captures measurements against the asset rather than just completions.
The parts whose absence turns a short repair into a long outage.
The PMs ChatterFix schedules against this equipment, with intervals and time estimates.

ChatterFix builds this asset, its components, and its PM schedule automatically when you pick your industry — then your technicians update it by talking, not typing.
