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

Topics:

  • What is the difference between a Classic (BI) unit and a PRO4850 and PRO3650?
  • 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.
