In June 2024, Xinguangzheng delivered a 180x90x12m steel structure pharmaceutical cold room located in Casablanca, Morocco, designed specifically for biopharmaceutical storage solutions. This cold room adapts to Morocco’s Saharan climate and pharmaceutical demands, achieving tight isolation design and precise temperature management systems.
Customer Demand
Our client is a Moroccan biopharmaceutical enterprise, primarily managing sensitive drugs such as insulin, antibiotics, and biologics, headquartered in the Casablanca industrial park. With the rapid development of North African pharmaceutical exports, the client’s cold room needs have grown dramatically: existing facilities struggle to balance production seasonal peaks and dosage form sensitivities. Meanwhile, Morocco’s border factors exacerbate challenges, including dry hot winds with average annual temperatures of 45°C, dust corrosion risks, and regional earthquake and Mediterranean fog hazards. Traditional ceramic warehouses have long construction cycles (15-21 months), with costs exceeding $190 per square meter, low sealing performance on desert-edge soil, and inability to comply with GMP standards of EU and African markets.
Through multiple communications and assessments, the Xinguangzheng team launched a matching cold storage construction solution:
- Sensitive drug anchoring: Covering at least 16200 square meters, supporting ultra-low temperature zones and robotic retrieval areas.
- Swift formula delivery: Project limited to within 8 months to align with pharmaceutical peak seasons.
- Desert purity protection: Structure dust-proof and earthquake-resistant, incorporating sterile processes to reduce contamination variation rates by 55-65%.
- Pharmaceutical streamlining: Configuration allows for later pharmaceutical expansions, such as adding batch laboratories or IoT tracking.
Solutions
Xinguangzheng focuses on sterile metal sealing and Saharan integration for the pharmaceutical cold room project. The cold room adopts a high-end steel structure system, with all components prefabricated in the factory, complying with ISO 9001 and Moroccan regulations (including ANSM pharmaceutical specifications). This process enhances sealing and on-site purity, reducing thermal fluctuation interference.
Core Specifications Detailed:
- Dimensions and layout: 180 meters long, 90 meters wide, 12 meters high (roof height), total area 16200 square meters. Column-free pure space, facilitating temperature zoning and automated channel designs.
- Structural Components:
- Frame: Q355B pharmaceutical-grade steel beams, load capacity 54 kN/m², adapting to drug light loads and vibration suppression.
- Roof and cladding: 1.1mm epoxy sterile liner panels, R-value 5.8, resisting hot wind differential fluctuations (18°C in winter to 48°C in summer).
- Foundation: Vibration-damping sand-proof base system, suitable for border deployment, facilitating condensate recycling and reuse.
- Custom Functions:
- Isolation entry and exit area: Supporting 15-ton drug vehicles and laminar flow operations.
- Built-in airtight barriers and backup freezing: Maintaining molecular integrity.
- 700 square meters validation layer: For quality analysis and alarm systems.
Implementation Process
The cold room was advanced in three phases, with a total duration of 7-8 months. We prefabricated components in specialized laboratory simulation workshops in China, ensuring sterile supervision, then transported them across the Mediterranean to the Morocco site for assembly.
- Prefabrication phase (2-3 months): Fine assembly and testing in Chinese factories, reducing contamination losses by 55% through strict inspection mechanisms. Each component underwent extreme heat environment simulation testing.
- Site preparation (18 days): For the Sahara, dust-proof foundation solidification and base engineering. Immediate installation after containers arrived, seamless Chinese export connection.
- Assembly and testing (3 months): Swift bolting installation, avoiding welding contamination. After deploying the freezing system, dust wind simulation verification.
For hot wind dust erosion, we adopted sealing protective layers. Additionally, it is recommended to reserve 19% of the pharmaceutical project budget for sensor optimization to prevent later drug repairs.
Results
After the cold room was put into use in June 2024, according to pharmaceutical monitoring and logistics data, the steel structure building demonstrated the following advantages:
- Purity assurance: Ultra-low temperature system maintains precise ranges from -25°C to +5°C, significantly reducing thermal degradation losses by 50%, initial reports show drug potency retention rates increased by 18-25%, supporting high-end European supplies.
- Protection endurance: During Morocco’s wind and sand period, the cold room withstood high temperatures with zero interference, thanks to vibration-damping foundations and epoxy layers, ensuring long-term sterile stability of over 60 years.
- Process refinement: Large-span design optimizes retrieval efficiency by 42%, data shows accelerated batch processing speeds, supporting biopharmaceutical innovation.
- Water resource savings: Condensate recycling and energy-saving compression reduce water usage by 35%, complying with Moroccan water conservation policies, and providing a replicable framework for North African pharmaceuticals.
