Sub-Zero Classic (BI) vs. PRO 48 and PRO 36 Series Refrigeration Comparison
Topics:

- Selling point differences between Classic and PRO models
- Selling features of Classic vs PRO models
- PRO 48 and PRO 36 versus Classic differences
Answer:
The key differences between the PRO Refrigeration (PRO4850 and PRO3650) and the Classic lines are as follows:
- PRO Refrigeration models have a more "industrial" look of a commercial kitchen than Classic models.
- With PRO models, the presence of the refrigerator in the kitchen is more apparent.
- If a freestanding unit is needed or the sides of the refrigerator will be partially exposed, Sub-Zero recommends the PRO line.
- The Classic line expands on the traditional look that Sub-Zero has had for decades.
