Overview
For -28 C duty in a hinged format, the FrostSwing F120H carries the full freezer brief: a 120 mm PIR insulated leaf, dual heated perimeter gaskets, and a heated threshold that keeps the doorway ice-free in humid Indian conditions. Cam-lift hinges close the heavy leaf positively, and the latch is a heavy-duty freezer handle designed to be operated with gloves on.
Every detail assumes a working freezer. The inside safety release is luminous and oversized — findable in the dark, in a freezer, with gloves on. An optional heated vision panel lets staff confirm stock or check for obstructions without breaking the cold chain to open the door. The dual gasket circuits give redundancy: if one heater circuit ever fails, the second still holds the seal line.
Egis positions the F120H on frozen stores, ice-cream hardening rooms and blast-freezer anterooms where a sliding door is impractical or overkill. Clear openings run from 800 to 1200 mm wide and 2000 to 2400 mm high. Where automation is justified, the FrostGlide F120 slider takes the same opening with hands-free operation.
How -28 C is held with a hinged leaf
Below freezing, the door's enemy is not just cold — it is the seal line. Moisture from the warm side migrates to the cold gasket, freezes, and the resulting ice progressively lifts the seal until cold pours out and the door freezes shut or open. The F120H answers with two heated gasket circuits plus a heated threshold: the seal line is held just above freezing on both the leaf and the floor, so the gasket always seats on a dry surface, even in monsoon humidity.
The hardware is specified for the duty, not adapted to it. The heavy-duty freezer latch is sized for gloved operation and sized for the leaf's real weight; the cam-lift hinges lift the leaf clear of the floor seal on opening so the seal never drags; and the safety release is oversized and luminous because a release that cannot be found in the dark with gloves on is not a safety device.

Typical applications
Frozen food stores
Dependable daily access for frozen inventory with the seal line held against humidity.
Ice-cream hardening rooms
Holds -28 C duty through the frequent door cycles of hardening-room operation.
Blast-freezer anterooms
Hinged format suits anteroom openings where a slider is impractical.
Seafood processing freezers
Washdown-tolerant faces and stainless hardware stand up to processing-hall duty.
FAQs
Why does the door need two heated gaskets?
Redundancy and coverage. Two circuits hold the full seal line above freezing even in extreme humidity, and if one circuit ever fails, the second still protects the seal. On a -28 C door, a single failed heater means ice, a broken seal and cold loss — the dual circuit removes that single point of failure.
Why is the threshold heated?
Because the floor is where ice forms first. Moisture tracks in on boots and pallets, freezes at the threshold, and lifts the bottom seal — or freezes the door shut. The heated threshold keeps the doorway ice-free so the leaf always seats and always opens.
Can someone trapped inside get out?
Yes. The inside safety release is luminous and oversized, designed to be found in the dark and operated with gloves on. It is a mandatory safety feature, tested at commissioning.
What happens in a power failure?
The door remains fully operable manually — the cam-lift hinges and latch need no power. The gasket and threshold heaters go off with the power, so in a prolonged outage the seal line should be checked for ice before resuming normal cycles.
What sizes are available?
Clear openings from 800 to 1200 mm wide and 2000 to 2400 mm high, in food-safe white GRP or coated steel with a stainless option.
How often do the gaskets need attention?
The heated gaskets are wear items. Egis recommends inspection on a cycle-count basis — high-traffic stores more often — and replacement when compression set or heater-circuit faults appear. The dual circuit means a single fault never becomes an emergency.
