The Summit ALFZ37BSSTBFROST is a 21"-wide Cold Cavern beer froster: a 2.68 cu.ft. all-freezer that Summit designs to store aluminum bottles and cans. Cabinet size is 32.0" high to the hinge cap x 20.88" W x 22.5" D, with a stainless steel door, towel-bar handle, and finished black cabinet, at a height Summit lists for use under many lower ADA-compliant counters.
Unlike the related ALFZ37BSSTB freezer, this model is listed with a temperature range of 24°F to 35°F and is pre-set at 24°F. Defrost is manual. The door is factory reversible rather than user-reversible. Summit also lists three wire shelves, three door shelves, a 3"-thick door, a magnetic bottle opener, and temperature and open-door alarms. Electrical listing is 115 V AC/60 Hz at 0.6 amps, with ETL / ETL-C safety listings.
- Depth with handle: 25.0"; depth with the door at 90°: 40.25".
- Front-breathing for built-in use; the finished cabinet also allows freestanding placement.
Is this the same freezer as the ALFZ37BSSTB? No. This version is a beer froster with a listed 24–35°F range and a 24°F pre-set. The ALFZ37BSSTB is a standard all-freezer listed at -13 to 5°F, and its door is user-reversible.
