Labor hours saved by larger pan surface areas, cost of maintenance (argon welding for leaks), and resale value of used equipment.

This paper would analyze the efficiency of the "drop flue" design commonly found in these pans. Drop flues increase the surface area exposed to the fire, allowing for faster evaporation. Grimm_4x12
