QuickFreeze Heritage · Retired 2021
QF+
QF+ was QuickFreeze’s in-rack, common-plenum blast freezing system — the platform that proved vacuum-pull airflow and led directly to today’s QFM. QF+ was discontinued in 2021 and replaced by the modular QFM, which carries its airflow philosophy forward in a per-pallet design.
The System That Led to QFM
QF+ pioneered the airflow approach that defines every QuickFreeze product today — pulling air through pallets instead of blasting at them.
Through the pallet, not around it
High-pressure fans created a vacuum that drew chilled air through every pallet, pulling heat away as fast as the product would release it. The same principle drives QFM today.
No sweet spots, no slow spots
Air was pulled uniformly through every position for consistent core temperatures across the whole rack — the food-safety foundation QFM inherited.
Adapted to pallet height
The exclusive swing gate adjusted to mixed pallet heights so short stacks didn’t compromise the rest of the rack — the idea that evolved into the dynamic AutoSeal.

Why QFM Replaced QF+
In 2021 QuickFreeze moved from the fixed in-rack QF+ to the modular QFM — a self-contained unit that freezes one pallet per cell, retrofits into standard racking, and adds the touchless AutoSense core-temperature sensing and the dynamic AutoSeal pallet seal. Same vacuum-pull airflow QF+ proved — now per-pallet, smarter, and connected.
