SUMMIT PROFESSIONAL CT-67 is our most deluxe under-counter refrigerator-freezer with standard glass shelves and a wine rack, . It has dual-evaporator cooling (for a freezer that really freezes!) with separate evaporators for the fresh food and freezer sections. The fresh food section has our unique 'hidden evaporator" (behind the rear wall) for a clean seamless interior, and a large interior. Base CT67 models include a fame to accept custom panels, and models with a "BI" suffix are UL approved for built-in use.
