1100m³ Rabies Vaccine Cold Room Solution for Chengdu Institute of Biological Products

Project Overview

Haocool recently delivered a turnkey 1100m³ 2–8°C vaccine cold storage project for Chengdu Institute of Biological Products, a subsidiary of China National Pharmaceutical Group (Sinopharm), one of the world’s largest pharmaceutical companies.

The client needed a multi-room, energy-efficient, GSP/ISO/EN-compliant cold storage solution to support its large-scale production of freeze-dried rabies vaccines.

This project was designed to solve several critical challenges faced by the client:

• Ensuring stable 2–8°C temperature for vaccine storage
• Achieving centralized monitoring & intelligent control
• Reducing long-term operating costs through high-efficiency equipment
• Meeting URS requirements and passing multiple certification standards
• Expanding storage capacity to support increasing vaccine output

What the Client Achieved After the Project

1. Enhanced Storage Capacity

The six vaccine cold rooms offer a combined storage volume of 1100 cubic meters, supporting:

• 300–400 pallets of freeze-dried vaccines
• Approx. 30–40 million doses (depending on packaging)

This significantly improved the client’s production and inventory turnover capability.

2. Stable 2–8°C Temperature for Biological Safety

The cold rooms maintain a precise 2–8°C temperature range with real-time monitoring, meeting strict vaccine preservation standards required by:

• GSP/GMP/ISO/EN
• National pharma testing specifications

3. Lower Operating Cost & Higher Energy Efficiency

By using frequency-conversion air-handling units and optimized airflow design:

• Energy consumption reduced by 20–25%
• Estimated monthly power use: 8,500–10,000 kWh
• Annual operating cost savings: USD 4,000–5,500

This was one of the client’s key priorities—achieving long-term energy savings without compromising performance.

4. Fast Installation & Commissioning

• Total installation period: approx. 32 working days
• System commissioning: 5 days
• Achieved operational readiness ahead of schedule, ensuring no delay to the vaccine supply timeline.
