AutoSeal — Patented Dynamic Pallet Seal for QFM

Patented · QFM Accessory

AutoSeal

A flexible, dynamic pallet seal that opens when the fan idles and form-fits when it starts. Built for the pallets you actually have — not the ones in a brochure.

Pallets Aren’t Perfect. Your Seal Shouldn’t Need Them To Be.

Real-world pallet stacks are uneven, varied, and rarely the size on the spec sheet. AutoSeal adapts.

Flexible

Form-fits to the pallet.

When the fan starts, AutoSeal molds itself around whatever pallet shape and stacking quality is actually in front of it. No gaps, no bypass air, no lost CFM.

Dynamic

Opens when idle.

Between cycles, AutoSeal opens out of the way. Pallet handling stays fast. No equipment to dodge, no manual repositioning.

Universal

Handles height variability.

Short pallet stacks have always been the worst-case for blast cells. AutoSeal closes the gap that used to force lower cell temperatures and longer cycles.

Why AutoSeal Matters

No more bypass air

Every CFM your fan moves goes through the pallet — not around it. That’s the whole game.

Stop dropping cell temperature

Conventional blast cells lower air temperature to compensate for poor sealing. With AutoSeal, you don’t need to. Energy savings follow.

Works with what you ship

Mixed pallet types, irregular stacks, slip sheets, varied heights — AutoSeal adapts to every cycle without operator intervention.

Pairs with AutoSense

Better seal + smart sensing = the shortest reliable cycle that physics will allow.

Proven in Side-by-Side Testing

18.7% Faster Freeze

In a controlled side-by-side comparison, pallets frozen with AutoSeal engaged reached target core temperature 18.7% faster than the same QFM line running without it — by eliminating the bypass air that robs the pallet face of cold airflow.

Engaged vs. Idle

AutoSeal form-fits to the pallet face when the fan starts, then opens out of the way between cycles.

Common Questions About AutoSeal

The patented dynamic pallet seal — answered.

What problem does AutoSeal solve?
Conventional blast cells lose performance to bypass air — air that goes around the pallet instead of through it. The worse the pallet stacking quality or the more pallet-height variability you have, the worse the bypass-air problem becomes. AutoSeal form-fits to whatever pallet is in front of it, eliminating the gap.
Does AutoSeal slow down pallet handling?
No. AutoSeal opens out of the way when the fan is idle. Pallet handling stays fast — no equipment to dodge, no manual repositioning.
How does AutoSeal handle short or irregularly stacked pallets?
AutoSeal is designed specifically for the worst-case scenarios that have always troubled blast cells: short stacks, mixed pallet heights, slip sheets, and irregular case stacking. The seal adapts dynamically each cycle.
Can I retrofit AutoSeal to existing QFM units?
Yes. AutoSeal retrofits to existing QFM installations and ships standard on new orders.
Do I still need to drop my cell temperature with AutoSeal installed?
A common workaround for poor sealing has been to lower cell temperature. With AutoSeal eliminating bypass air, that compromise is unnecessary — which saves energy as well as cycle time.
