The Most Regulated Thermal Environment
in Industry. Engineered Accordingly.
GDP-compliant controlled-environment infrastructure with validated protocols, in-house IQ/OQ/PQ documentation, and precision HVAC for vaccines, biologics, APIs, and temperature-sensitive formulations.
The Most Regulated Thermal Environment in Industry.
Pharmaceutical cold chain infrastructure is not ordinary refrigeration. It must satisfy Good Distribution Practices (GDP), withstand regulatory inspections by CDSCO, FDA, and EMA, maintain validated conditions across seasonal extremes, and provide auditable electronic records under 21 CFR Part 11.
A single temperature excursion in a biologic or vaccine storage environment can result in batch losses worth millions i.e., alongside regulatory action, supply interruption, and patient safety consequences. Cueron designs facilities to prevent these events by engineering compliance in, not documenting it after the fact.
Multi-Zone Temperature Architecture
Five distinct temperature zones, each independently validated and continuously monitored, covering the full pharmaceutical storage spectrum.
Built for Every Major Regulatory Framework
Our facilities are designed, documented, and validated to satisfy the world's most stringent pharmaceutical storage regulations i.e., not as an afterthought, but as the foundational design principle.
WHO GDP Guidelines
Good Distribution Practices
- Temperature-controlled transport and storage validation
- Qualification of cold rooms, refrigerators, and freezers
- Documented deviation management procedures
- Personnel training and competency records
- Supplier qualification and audit trails
EU GMP Annex 15
Qualification & Validation
- Installation Qualification (IQ) for all cold chain assets
- Operational Qualification (OQ) with loaded/unloaded mapping
- Performance Qualification (PQ) over seasonal extremes
- Periodic re-qualification schedules (annual or bi-annual)
- Change control procedures for equipment modifications
US FDA 21 CFR Part 211
Current Good Manufacturing Practice
- Written temperature control procedures (SOPs)
- Calibrated and validated monitoring instruments
- CAPA documentation for excursion events
- Label storage requirements (USP <659>)
- Annual product reviews including temperature data
21 CFR Part 11
Electronic Records & Signatures
- Audit trail for all electronic temperature records
- Role-based access control with unique user IDs
- Time-stamped, tamper-evident data logging
- Electronic signature validation for batch release
- Compliant LIMS/EDMS integrations
Cold Chain Validation Protocol
Every facility undergoes our rigorous three-stage qualification process aligned with EU GMP Annex 15 and WHO Technical Report Series No. 961.
IQ i.e., Installation Qualification
- Verification of equipment installation per manufacturer specs
- Documentation of as-built drawings and P&IDs
- Calibration certificate review for all instruments
- Utility connections verification (power, water, drainage)
- Alarm system functionality check
Temperature Excursion Response Protocol
Automated severity classification with tiered response workflows i.e., from auto-logged minor drifts to critical quarantine events.
Minor Excursion
Threshold: < 1°C beyond limit, < 15 min
Automated log, no product impact assessment required if within validated drift
Major Excursion
Threshold: > 1°C beyond limit or > 15 min duration
Automated alert → QA review → product stability assessment → disposition decision
Critical Excursion
Threshold: > 5°C beyond limit or freeze event in +2/+8°C zone
Immediate quarantine → recall risk assessment → regulatory notification if batch release affected
Cleanroom-Integrated Cold Storage
For biologics, cell therapies, and sterile injectables i.e., our cold rooms can be integrated within ISO-classified cleanroom environments.
ISO 14644-1 Cleanroom Classification Compatibility
Flush Panel Joints
Crevice-free construction for cleaning validation and microbial control
Vision Panels
Double-glazed, heated observation windows for process monitoring without entry
Pressure Cascades
Positive pressure differentials (10-15 Pa) to prevent particulate ingress
Technical Specifications
Engineering parameters for our pharmaceutical-grade cold chain facilities.
