Handover: Must have
Each supplier must restate vessel and jacket duties, heating area, agitator rpm, nozzle facing, lining inspection records, packing method, shipping weight versus installed weight, and whether FAT/SAT attendance, spare parts and training days sit inside the machine line. A handover pack that only repeats a catalog gallon figure cannot be compared. Throughput should be written as batch size and cycle time with named heat-up and cool-down tasks so duty cycle is visible.
Tradeoff
A lower vessel price can hide agitator drive, lining repair access, crate engineering or on-site nozzle hook-up. The tradeoff is not “cheap versus premium branding”; it is whether the quoted boundary includes the pressure-containing jacket, the mixing assembly and the documents a plant engineer needs before lifting. Prefer the offer that names exclusions over a round number that later grows during installation.
