It runs the same product heat load math our engineers use for first-pass sizing: published specific heats, latent heat of fusion, and freeze points for over 100 products, plus the fan heat of the QuickFreeze equipment itself and a 5% peak factor. What it can’t see is your building — envelope, infiltration, room fans, traffic, and defrost all add load, which is why final design always goes through a QuickFreeze Blast Ready review.

Cycle time depends on product, pallet weight, and how cold you run the room — as a rule, room air should be at least 5°F below the product target temp. A typical 1,650 lb chicken pallet going from 40°F to 0°F in a −12°F room runs about 23 hours, which is the default here. If you know your actual validated cycle time, use it.

Use the net product weight on the pallet — what you actually need to freeze — not the pallet and packaging. 1,650 lbs is a common figure for boxed protein; produce and bagged product often run lighter. If your weights vary, size with your heaviest regular pallet.

QFM is our cell-based blast freezing system — one pallet per cell, with 550 W of fan power per pallet position. Spartan is the two-deep version (two pallet positions per unit, 275 W per position). QF+ is rack-based freezing where positions round up to your racking layout (levels × rows) and fan power is 7/16 HP per position. The calculator sizes all three from the same inputs so you can compare.

We only list products with complete published thermophysical data (specific heats, latent heat, and freeze point). If yours is missing, email [email protected] — we can usually source or derive the values and run the numbers for you.
