Our read & the right size
At 7.6 kWh/day, the Delfield 6151XL-SH runs more efficient than 73% of the 11 comparable 4-door reach-in freezers we track — about $67/yr under the median comparable model.
How we compare: “comparable” = matched on door count (4-door) and type (reach-in freezer), among ENERGY STAR-certified models with a published kWh/day figure — the 11 such units we track · group median 8.73 kWh/day (≈ $519/yr) · this model 7.6 kWh/day · source: ENERGY STAR certified product data, as of July 2026.
A 4-door reach-in freezer is a specialty footprint — match door count to how much cold product you turn in a shift; empty sections still cost energy to cool.
41.37 cu ft is roughly 2.1× a typical home refrigerator — about 21 full sheet pans or ~34 cases of product (varies with shelving).
