  1. 20 percent per year
  2. 30 percent per year ✔
  3. 10 percent per year

Why: Industrial process refrigeration, which includes chemical plants, industrial ice machines and ice rinks, gets the highest threshold at 30 percent a year. Commercial refrigeration is 20 and comfort cooling is 10.

Huh, didn't know that: If an appliance is used for both industrial process and other work, it counts as industrial process if 50 percent or more of its capacity is.

The dad joke
Why are industrial plants the most relaxed about leaks? They get a 30 percent head start.
