What is the life expectancy of a water softner resin?

Indefinite.

I have an industrial style installation

We have a similar setup. It started as a Culligan rental that, after a year
or two, I purchased. When we moved, we moved the unit(s).

We have lived here since 1991 and I recall it was used at the previous house
for 3-4 years
