Custom produced from 2.00m to 13.50m with zero jobsite waste and full export logistics.
01 Product Overview & Primary Use
Designed specifically for -40°C blast freezing tunnels and commercial sub-zero preservation, these panels incorporate an extended double-stepped labyrinth edge profile combined with heavy-duty internal eccentric cam-locks, preventing thermal leakage under extreme temperature differentials.
Engineered for ultra-low temperature (-40°C) blast freezing chambers, -40°C Blast Freezer & Deep Freeze Panels combines 120–200mm fire-retardant PIR core with deep double-labyrinth interlocking tongues. Dual cryogenic sealant channels and thermal break barriers eliminate vapor transmission, thermal stress cracking, and internal frost formation.
02 -40°C Double Labyrinth Section & Cryogenic Geometry
Blast freezer panels are engineered for -40°C cryogenic environments in 1000 mm width and 120, 150, 180, and 200 mm thicknesses. Deep double tongue-and-groove labyrinth joints with perimeter heavy-duty cam-locks every 800mm and dual cryogenic mastic grooves halt vapor drive completely, supplied in custom lengths up to 13.50m.
- ▪ Modular Width: 1000 mm (1.00 m)
- ▪ Operating Temperature: -25°C ile -45°C Ekstrem Şoklama
- ▪ Joint Mechanism: Double Labyrinth PIR + Cryogenic Butyl Mastic
03 -40°C Cryogenic PIR Insulation & Double Labyrinth
In -40°C blast freezers, a 70–80°C temperature differential creates intense vapor drive. Shock panels feature 120–200mm PIR insulation with deep double-labyrinth interlocking tongues and cryogenic mastic channels to completely halt vapor transmission, preventing internal frost buildup.
04 Cryogenic Corrosion Resistance & Inox Skin Options
In -40°C blast freezers, panel skins are formed from 0.50–0.60mm galvanized steel with 120µm Food Safe antibacterial PVC film or AISI 304 stainless steel for aggressive marine and meat packing environments. Specialized cryogenic coating resins prevent micro-cracking and delamination under extreme cold.

06 Standard Hygienic Colors & Stainless Steel Finishes
Cold room panels and doors are supplied with Food Safe antibacterial RAL 9002 coated steel and AISI 304 stainless steel facings as standard according to HACCP hygiene regulations.
07 Food Hygiene, Safety & Thermal Insulation
Flame-retardant PIR (Polyisocyanurate) core achieves EN 13501-1 Class B-s1,d0 fire classification. Carbonizes during fire exposure to suppress toxic smoke production and eliminate flaming droplets.
40–42 kg/m³ rigid PUR/PIR core with integrated steel eccentric cam-locks guarantees airtight joints with zero thermal bridging, cutting refrigeration energy bills by up to 40%.
08 Assembly & Joint Detailing
1. Cryogenic Dual Mastic Lines: Dual continuous beads of non-hardening cryogenic mastic are applied within the double tongue-and-groove channels to resist severe vapor pressures.
2. Heavy-Duty Cam-Locking: 120–200mm PIR panels are clamped hermetically using internal steel cam-locks spaced every 800mm.
3. Heated Pressure Relief Valves: Dual-action 220V heated pressure relief valves are installed to balance sudden air pressure changes during door operation and blast freezing cycles.
4. Thermal-Break Corner Transitions: All corner junctions are reinforced with specialized thermal barriers and hygienic covings.
