China cold storage solution provider
Project Overview
Sansure Biotech Co., Ltd., headquartered in Changsha, Hunan, is a leading biotechnology company specializing in molecular diagnostics, reagent R&D, and production. To meet its expanding demand for biomedical storage and ensure compliance with GSP, ISO, and EN certification standards, Sansure partnered with our team to design and build a 600㎡ (1,852m³) pharmaceutical cold storage facility.
Project Scope
The cold storage complex includes six temperature-controlled chambers:
- 2 Refrigerated Rooms: +2°C to +8°C
- 2 Freezer Rooms: –15°C to –25°C
- 1 Buffer Room: +2°C to +8°C
- 1 Packing Room: 0°C to +15°C
All rooms are designed for temperature adjustability and precise humidity control, suitable for sensitive pharmaceutical and diagnostic products.
Technical Highlights
- Dual Refrigeration System (One Operating, One Standby):
Each main cold room is equipped with Bitzer (Emerson Copeland) scroll compressors, automatic switching, and load balancing to ensure uninterrupted operation. - High-Efficiency Air Coolers:
Equipped with Bitzer high-performance air coolers featuring imported Ziehl-Abegg or EBM motors, providing stable air circulation and uniform temperature distribution. - Insulation Materials:
Entire facility uses 150mm polyurethane sandwich panels with B1 fire resistance, while freezer floors are built with 150mm XPS insulation boards, minimizing energy loss. - Smart Control System:
Integrated Siemens automatic temperature control with Schneider electronic components, featuring:- Remote monitoring via PC and mobile app
- SMS and centralized alarm system
- Audit trail and GSP-compliant data recording
- Auto-start backup unit during high load or failure
- Door-signal and temperature recovery tracking
Project Performance
- Total Construction Period: ~60 days (from design to commissioning)
- Cold Storage Capacity: ~180 tons of biological reagents and diagnostic materials
- Average Daily Power Consumption: 220–260 kWh (≈20% lower than standard systems due to inverter compressors and smart defrost control)
- Temperature Stability: ±0.3°C accuracy in all chambers
Customer Value
With the completion of this project, Sansure Biotech:
- Achieved GSP/GMP-certified pharmaceutical storage compliance
- Significantly improved storage efficiency and energy savings
- Ensured continuous, stable supply chain for diagnostic reagent production
- Enhanced traceability and data transparency through the smart monitoring system
The project enables Sansure to safely store and manage temperature-sensitive biomedical materials year-round, supporting its goal of becoming a leading diagnostic reagent manufacturer in China.
