Ive been working on Hoshizaki's for about 5 years now and Ive seen several flavors of failure. Most of them are either self explanatory or can be figured out. I came across this evaporator at one of my accounts and it caused all kinds of problems making ice, a bunch just came out as snow. The bow of this evap was actually a lot worse when it was installed in the machine.
My question is, what causes the bow, specifically? What is the process?
Ive seen ice form in between and expand causing the separation we love so much, but this evap is still attached to the tube.
