Inside the line — three components we ship to you
A discontinuous cold-room panel line is built from three core components. Each photograph below is the actual equipment we ship. Architecture is intentionally simple: one horizontal press body holding the panel between heated platens, a high-pressure PU foaming machine feeding the cavity, and the steel forming platens that define your panel length (3/6/9/12/18 m) and width (1.2 m fixed).
Intermittent press (the line body)
Welded-steel horizontal book press, 1.2 m × N-metre envelope. Top + bottom heated platens (40–60°C, PID control) clamp the steel-foam-steel sandwich while PU foam cures. Side-mounted hydraulic clamping cylinders distributed along the press length deliver parallel pressure across the full panel area. Single-press footprint ~25 × 7 m. Sized per order — talk to us with your daily-output target.
See production line catalog →
High-pressure PU foaming machine
High-pressure PU machine (200–600 g/s) feeds the press cavity through a positionable injection arm. POL + Cyclopentane + ISO metering with closed-loop pressure control. ATEX Zone 1 cyclopentane-ready as standard; HFO-1233zd(E) configuration available for EU 2025+ markets. Recipe calibrated to your panel thickness and target k-factor (0.022 W/m·K typical).
See PU foaming machines → Steel forming platens (panel-length defining)
Hot-rolled steel platens — 1.2 m wide × 3 / 6 / 9 / 12 / 18 m long. Internal heating channels matched to PID temperature loop. Surface ground flat to ±0.2 mm for parallel pressure transfer. Five standard mould sets cover ~95% of cold-room markets; non-standard lengths (4.5 / 7.5 / 15 m etc.) achievable as custom (4–6 week tooling lead time).

Certifications
For factory owners planning to build a discontinuous cold-room panel plant. For factory owners planning to build a discontinuous cold-room panel plant. We ship the intermittent press + matched PU foaming machine + first PU recipe + commissioning. Continuous double-belt lines are NOT our scope (those come from European OEMs at 3–5× the capex).
Is this line for you?
A discontinuous panel line is a specific architecture choice. Below: who wins with it, and who should buy something else.
Yes — this line fits you if:
- You're building a NEW cold-room panel plant targeting modular cold rooms, commercial cold storage, blast freezer, or specialty thickness panels
- Your target monthly output is 4,000–12,000 m² (single-shift 200–500 m² per press; 2 presses + 2 shifts = up to 22,000 m²/month)
- Your destination markets are MENA / Africa / Southeast Asia / Latin America — markets that prefer flat-packed camlock panels and modular cold-room kits
- You need flexibility: 5 standard panel lengths (3/6/9/12/18 m), 50–250 mm thickness range, multiple edge profiles, multiple steel facings
- You're cash-flow sensitive: capex USD 400K–900K is reachable; USD 2M+ for a continuous double-belt line is not (yet)
No — buy something else if:
- Your target monthly output is > 15,000 m² of one standard white wall panel — that's continuous double-belt territory (Hennecke / KraussMaffei in Europe). We can refer you, but it's not what we ship.
- You want highly automated, single-operator continuous production — discontinuous press is operator-paced (4–6 people per shift)
- You only need 1–2 panels for a project (you're a contractor, not a factory) — buy finished panels from a manufacturer; don't build a line
Discontinuous (intermittent press) vs continuous (double-belt) — an honest comparison
Two architectures dominate cold-room panel production. They serve different factory profiles. Here's a fair side-by-side so you can verify discontinuous is right for you — not just believe what we tell you.
| Aspect | Discontinuous press (our scope) | Continuous double-belt (we don't ship this) |
|---|---|---|
| Monthly output (1 press × 2 shifts × 22 days) | 4,000 – 12,000 m²/month | 15,000 – 60,000 m²/month |
| Panel length flexibility | 5 fixed standard lengths (3/6/9/12/18 m) — match your container loading + market | Continuous saw-cut 2–14 m — flexible but wasteful for short panels |
| Panel thickness range | 50 – 250 mm (handles thicker walls than continuous) | 50 – 200 mm typical max |
| Best-fit panel type | Modular cold-room camlock panels · super-thick blast-freezer walls · stainless inner-skin pharma panels · specialty thickness | Standard white wall + roof panels in large volume |
| Capex (line + press + PU foaming + jigs) | USD 400K – 900K | USD 1.8M – 3.5M |
| Factory footprint per line | ~25 × 7 m per press (250–400 m² total) | 80–150 m long press hall (600–1,200 m²) |
| SKU / thickness changeover | 5 min (swap mould stack) | 30 min (adjust press gap + side rails) |
| Right buyer profile | First-time panel plant · modular cold-room exporter · specialty thickness · cash-flow sensitive | Volume white-panel commodity supplier · already has continuous experience |
Continuous lines we don't ship. If your target market is large-scale standard white panels at 30,000+ m²/month, talk to European continuous-line vendors. For modular cold rooms, specialty thickness, and most factories targeting MENA / Africa / SE Asia / LATAM exports — discontinuous wins on capex, flexibility, and container-loading economics.
1.2 m × 5 standard panel lengths — sized for export container loading
Discontinuous press = mould-defined length. We ship five standard moulds: 3 / 6 / 9 / 12 / 18 m. Width is fixed at 1.2 m — the industry standard that matches EN 14509 sampling width and most cold-room module spans. Pick which length(s) match your target market and container loading economics.
| Panel length | Target market / typical use | Single-panel area | Container load efficiency |
|---|---|---|---|
| 3 m | Small-format walk-in coolers · LATAM / Africa modular cold rooms (4 × 3 × 2.5 m room kits) | 3.6 m² | 40' HC: ~600 panels |
| 6 m | Standard cold-storage rooms (6 × 4 m halls) · SE Asia / MENA modular kits · reefer container inner-lining | 7.2 m² | 40' HC: ~280 panels |
| 9 m | Mid-size cold-storage warehouses (4–6 m ceiling height) · food-processing back-rooms | 10.8 m² | 40' HC: ~180 panels |
| 12 m | Industrial cold-storage walls + roof spans (single-panel full wall, no horizontal joint) | 14.4 m² | 40' HC: ~130 panels |
| 18 m | Large food-processing plants · long-span roof panels (un-supported) · multi-temp logistics warehouses | 21.6 m² | 40' Open-Top: ~85 panels |
Width 1.2 m is industry standard — matches EN 14509 sample width, fits most cold-room wall modules. Non-standard lengths (4 / 7.5 / 15 m etc.) are achievable but require a custom mould (4–6 week lead time, USD 30K–60K per mould).
Sizing guide — daily output target → line configuration + capex estimate
Tell us your target daily output and primary panel-length mix; we co-spec the press count, PU machine size, layout, operator headcount and capex. Below: three reference tiers using market-average pricing — your actual quote depends on PU chemistry, steel coil prep, automation level, and destination market certifications.
| Target daily output | Monthly equivalent (22 working days) | Press configuration | PU foaming machine | Operators per shift | Footprint | Capex estimate (market average) |
|---|---|---|---|---|---|---|
| 200 m²/shift | ~4,400 m²/month | Single 6 m press | Low-pressure PU machine (200 kg/h) | 4 people | ~250 m² | USD 450K |
| 350 m²/shift | ~7,700 m²/month | Single 6 + 9 m mould stack on one press | High-pressure PU machine (400 kg/h) | 5 people | ~320 m² | USD 625K |
| 500 m²/shift | ~11,000 m²/month | Single 6 / 9 / 12 m mould stack on one press, or 2 presses for SKU mix | High-pressure PU machine (600 kg/h) | 6 people | ~400 m² | USD 825K |
Capex above is market-average for a complete press + PU foaming machine + first mould set. Add ~USD 60K per additional standard-length mould; add ~USD 30K for the cut-to-length saw add-on; add ~USD 80K for the coil-feed + profiling pre-station if you want to roll your own steel facings. Final number lands on the engineering call.
What's inside a cold-room sandwich panel
A cold-room panel is steel skin + PU foam core + steel skin. The bond between steel and foam decides whether the panel passes EN 14509 / ASTM E72 testing and whether your cold room is still airtight 20 years later.
Outer steel facing: 0.4–0.8 mm galvanized (Z140/Z275), pre-painted (PE / PVDF / polyester topcoat in white / gray / blue), or stainless (304 / 316L for food-grade or coastal markets).
PU foam core: 50–250 mm rigid PU foam, density 38–42 kg/m³, k-factor 0.022 W/m·K, closed-cell content ≥92%. Foamed in-situ in the press. 20–30 year design life.
Inner steel facing: same materials as outer. Often 0.4–0.5 mm food-contact pre-painted polyester for cold rooms; stainless 304 for pharma / food-processing where cleanability matters.
Edge profile (your buyer's choice): tongue-and-groove (most common, gravity self-seal) · cam-lock (mechanical lock for modular cold rooms, flat-pack export) · flat-edge (for factory-welded big-room panels). All three are supported on our line.
Steel-to-foam bond: PU foams directly to clean galvanized / painted steel. For stainless or special coatings, a two-component PU adhesive primer is applied before pressing (see our adhesive dispenser catalog).
EN 14509 compliance — what passes, what fails, what it costs
EN 14509 is the European harmonized standard for self-supporting double-skin metal-faced insulating panels. CE marking under EN 14509 is mandatory for selling cold-room panels into any EU country. Below: what the standard tests + the typical numbers a well-built discontinuous panel hits.
Bond strength (steel-to-foam tensile pull-off): EN 14509 requires ≥0.1 MPa. Typical discontinuous panel achieves 0.12–0.18 MPa.
Bending strength: 3-point bending test on full panel, span 3 m. Panels rated for floor / wall / roof load by deflection vs load curve.
Reaction to fire: EN 13501-1 classification. PU panels typically B-s2,d0 (B with low smoke, no droplets) or B-s1,d0 with flame retardant additives.
Thermal conductivity: EN 12667 hot-plate test. k-factor measured at mean temperature 10°C. Must match declared value (typically 0.022 W/m·K).
Water absorption: 28-day soak test. Foam volume increase must be < 3% (cold-room PU achieves 1.5–2.5%).
Fastener pull-out: self-drilling screw + nut test simulating site installation. Pull-out resistance ≥1.5 kN. Camlock-edge panels meet this directly.
Full EN 14509 certification testing at TÜV / Bureau Veritas / Intertek runs USD 30K–60K and 8–12 weeks. ASTM E72 (US) and GB/T 23932 (China) are equivalent regional standards. We supply the panel — you submit it to your chosen lab.
Five cold-room panel end-markets — pick which one(s) your factory serves
Cold-room panels go into 5 distinct end-markets, each with its own thickness, coating, and certification requirements. Discontinuous press is strongest in 1, 2, and 3 below.
Modular cold rooms (flat-packed, camlock edge, exported to MENA / Africa / Southeast Asia / Latin America): 100 mm panels with cam-lock edge profile. On-site assembly by local installers. ~10% of global panel market by volume but the FASTEST GROWING segment — discontinuous press is the right tool here.
Commercial cold storage: walk-in coolers + freezers for supermarkets, restaurants, hotels. Standard 100 mm (cooler) and 150 mm (freezer) panels. Pre-painted white steel facings. ~40% of cold-room panel market by volume.
Industrial freezer rooms: food processing plants (ice cream, frozen meat, seafood), blast freezer rooms at -30°C to -40°C. 150–200 mm panels (sometimes 250 mm — only discontinuous handles this). ~25% of market.
Pharmaceutical cold storage: regulated drugs, vaccines, biological samples. Often 100–150 mm panels with stainless 304 inner facing (cleanability + corrosion). Sometimes GMP-validated. ~15% of market, premium pricing.
Refrigerated truck body + reefer container insulation: 50–100 mm panels with aluminum / GRP inner facing. Vibration-resistant bond requirements. ~10% of market.
Project timeline + factory infrastructure requirements
A discontinuous panel line ships in 2–3 × 40' containers (vs 6–8 for a continuous line) — that's a third of the sea-freight cost. Total project timeline from PO to first panel: 4–5 months.
- 1
Civil works (Weeks 1–4): Foundation pad with light anti-vibration matting, ≥6 m ceiling clearance, 380V industrial 3-phase power (40–90 kW per press), compressed air supply (≥0.7 MPa), 5-ton overhead crane for mould handling.
- 2
Shipping (Weeks 4–10): The line ships in 2–3 × 40' containers. Plan customs clearance + inland trucking — container count is low enough to land in one delivery window.
- 3
On-site installation (Weeks 10–13): Our engineer team (3–4 people) assembles the press, PU foaming machine, raw-material skid, and first mould set. Calibration of press parallelism, heated platen control, PU pressure / flow.
- 4
Commissioning + first production (Weeks 13–15): First 20 panels for calibration (often scrapped — material cost USD 2K–4K). Iterate press gap, platen temperature, foam recipe until panel passes bond + thickness + density QC.
- 5
Operator training + handover (Weeks 15–17): Train 4–6 of your operators on press operation, PU recipe management, mould changeover, daily maintenance. Hand over QC inspection protocols + spare-parts list. We stay on-site for the first week of full production.
