China cold storage solution provider
If you’re storing flammable semiconductor materials like photoresists, solvents, or etching agents (e.g., acetone, IPA, TMAH), a standard cold room won’t cut it. One spark from a non-certified motor—and your inventory, facility, and team are at risk.
That’s why ATEX/IECEx-certified explosion-proof cold rooms are non-negotiable for ISO 14644 cleanrooms, wafer fabs, or chemical warehouses.
But before you ask, “How much per square meter?”—ask this:
“For my budget, how many drums or IBC totes can I safely store at 5°C—and will it pass international safety audits?”
📏 Storage Capacity: How Much Can You Actually Store?
Semiconductor chemicals are typically stored in:
- 200L steel drums (stacked 2–3 high)
- 1,000L IBC totes
- Small reagent bottles in ventilated cabinets
With proper explosion-proof racking and 1m safety aisles:
| Cold Room Size | Usable Volume | Typical Storage Capacity |
|---|---|---|
| 50 m² | ～250 m³ | 120–150 x 200L drums or 25 x 1,000L IBCs |
| 100 m² | ～500 m³ | 250–300 drums or 50 IBCs |
| 500 m² | ～2,500 m³ | 1,200–1,500 drums or 250 IBCs |
💡 Most clients design for 30–90 days of buffer stock—enough to cover supply chain delays without overstocking hazardous inventory.
💰 Real Turnkey Cost (USD) – Explosion-Proof Cold Room
All systems include:
- ATEX/IECEx Zone 1 or Zone 2 certified components (compressors, fans, lights, sensors)
- Double-skinned 100–120mm fire-rated PU panels (Class B1/B-s1,d0)
- Intrinsically safe control panel with remote alarm
- Explosion-proof ventilation & leak detection
- Temperature stability: ±0.5°C at 0–10°C
| Size | Total Investment (USD) | Key Certifications | Ideal For |
|---|---|---|---|
| 50 m² | 48,000– 62,000 | ATEX II 2G Ex db IIC T4, IECEx | Small R&D labs, pilot lines |
| 100 m² | 85,000– 110,000 | ATEX + FM Approved (optional) | Mid-sized chemical storage |
| 500 m² | 380,000– 480,000 | Full IECEx + local compliance (SASO, BIS, etc.) | Wafer fabs, distribution hubs |
✅ Turnkey price includes:
- Explosion-proof refrigeration unit
- Certified electrical system
- Installation, commissioning & safety documentation
❌ Excludes: Civil works (concrete slab, firewalls)
🌍 Real Projects Across High-Growth Regions
Dammam, Saudi Arabia – Electronics Assembly Plant
- Need: Store 300 drums of photoresist at 5°C; comply with SASO & NFPA 30
- Solution: 90 m² ATEX Zone 2 cold room with emergency venting
- Cost: $ 92,000 – Result: Passed SABER certification; avoided $ 150K in compliance fines
🔑 Why Standard Cold Rooms Fail for Semiconductor Chemicals
| Risk | Standard Cold Room | Explosion-Proof Cold Room |
|---|---|---|
| Electrical Spark | ❌ Non-certified motors/fans | ✅ ATEX/IECEx sealed units |
| Temperature Drift | ±2–3°C → solvent degradation | ✅ ±0.5°C stability |
| Audit Compliance | Fails SEMI, OSHA, NFPA | ✅ Passes global safety checks |
| Insurance Validity | May void policy | ✅ Covered under industrial insurance |
⚠️ Warning: Using non-certified equipment in flammable storage = legal liability + insurance denial.
