Our read & the right size
At 2.66 kWh/day, the IDW G-37SI-N-3-3-5-B-5 runs in the less-efficient 63% of the 293 comparable 2-door reach-in refrigerators we track — about $27/yr over the median.
The two-door reach-in (~43–49 cu ft) is the workhorse of most kitchens: enough cold storage for a full line without a walk-in's footprint. It's the default unless you're very small (one door) or high-volume (three).
33.8 cu ft is roughly 1.7× a typical home refrigerator — about 17 full sheet pans or ~28 cases of product (varies with shelving).

Health-department & code relevance NSF/ANSI 7
Commercial kitchens holding cold TCS foods need NSF-listed refrigeration that holds 41°F (5°C) or below (FDA Food Code 3-501.16). Equipment must be commercially certified for sanitation (4-205.10, NSF/ANSI 7). This model is ENERGY STAR certified; confirm the NSF mark on the cut sheet.
