Seems to me that half of Sub Zero owners complain about them breaking down.
One...you are asking me about objective evidence, yet the basis of your claim is based on your dubious imaginary knowledge of half of all Sub Zero fridges?????
Two...my post was specifically regarding the Traulsen, not Sub Zero.
But to answer your question...
Commercial use requires high standards of food safety and freshness, as well as being built well enough to withstand many years of hard usage
They have a long track record in commercial applications. Do you doubt a commercial kitchen environment is tougher on the unit than a residential application?
...the entire unit, inside and out, is all heavy gauge stainless steel, which improves
food safety, cleaning and unit lifespan
Heavy gauge stainless steel vs plastic. This seems pretty obvious to me.
I could go on, but the point is it performs better, which actually translates into real world advantages in terms of what its job is...to keep food as fresh as possible, and do its job for a long time
without having to be replaced or suffer breakdowns or require maintanance.
Track record and obvious design/parts superiority. Traulsen made its name in the commercial industry, which is based on performance, not curb appeal. They don't make "residential" units...some people just adapt them for residential use, and the UR48DT model happens to be quite good looking and most suited to a residential kitchen. Other manufacturers just make their residential-specific units look like commercial units, cause that's been the "in" thing to do.
As far as domestic/residential units go, Sub Zero is
a superior product.
Our own SZ, we inherited when bought the apartment - I believe it was installed in 2002 (by hipsters
) and shows no signs of fatigue.
That's all very funny, but the real trick...is to know when to quit.
