High-speed freezer door with air barrierGIESSE AUTO FREEZER AChigh-speed freezer door with air barrier
High-speed freezer door by GIESSE with an air barrier for low-temperature zones.

Product description
AUTO FREEZER AC is a high-speed freezer door by GIESSE with an active air barrier for freezers and cold-chain objects with large temperature differences.
Unlike the freezer door without a barrier (AUTO FREEZER), an air curtain complements the insulation of the low-temperature zone — even during the open passageway.
The model solves the problem of maintaining temperature in the freezer under intensive traffic: a double PVC curtain forms an insulating chamber, and heating of the automation, guides and inter-curtain space prevents freezing. Confirmed durability: 1,000,000 cycles per EN 12604.
Applications
Freezers and cold-chain sites, where the active air barrier supports insulation of the low-temperature zone.

Doors with an air curtain – AC
Why this model?
AUTO FREEZER AC is chosen for freezers with intensive traffic, where an active air barrier is needed in addition to the double curtain. Without a curtain AUTO FREEZER suffices; for positive-temperature cold stores — AUTO FRIGO AC.
FAQ
Which door is suitable for freezers with intensive traffic?+−
For freezers with a high passageway frequency, a door with a double PVC curtain and air barrier is chosen — AUTO FREEZER AC works down to -25°C on the cooled side at temperature differences of up to 45°C.
What does the air barrier do in a freezer?+−
The barrier supports the insulation of the low-temperature zone even when the door is open — it limits the entry of warm air during the passageway.
Which parameters are confirmed?+−
Maximum clearance 5000 × 5000 mm, opening up to 1.5 m/s, closing 0.5 m/s, durability 1,000,000 cycles per EN 12604, power supply 230 V single-phase, operation down to -25°C, temperature difference up to 45°C.
Why are the automation and guides heated?+−
Heating of the automation, guides and inter-curtain space prevents the door elements from freezing in the freezer zone.
How does AUTO FREEZER AC differ from AUTO FRIGO AC?+−
AUTO FRIGO AC is the insulated door for positive-temperature cold stores; AUTO FREEZER AC has a double curtain, heated guides and automation and a working range down to -25°C — it is the freezer door.
How do you prepare a quote request?+−
Give the temperatures on both sides of the opening, dimensions, traffic frequency and a humidity description — we will choose the configuration with or without an air barrier.
