Guangzhou, China - GE Pilot Platform Bio-Tech Park Cold Storage

Project Basic Information

Located in Huangpu District, Guangzhou, the project supports the R&D and production demands of the GE Pilot Platform. The complete refrigeration system consists of three core modules: high-temperature cold storage, low-temperature cold storage, and an ethylene glycol chilled water system.

It adopts a combined technical approach of direct-expansion refrigeration and indirect cooling with secondary coolant, satisfying diverse temperature requirements and fulfilling various storage and process cooling needs for bioreactors, biological samples and laboratory consumables. From design, equipment selection and on-site installation to commissioning and delivery, the project strictly complies with bio-laboratory and pilot platform specifications to guarantee long-term stable system operation.

Customer Core Requirements

Bio-pilot platforms impose strict requirements on temperature fluctuation, humidity control, equipment redundancy, low noise operation and environmental protection. Temperature precision, operational stability, equipment backup, and eco-friendly low-noise operation are all critical - a failure in any one can lead to experimental data loss, sample damage, and production disruption. This project targets four core needs to achieve high efficiency, stability and low failure rates.

Core requirements checklist:

• Multi-temperature zone integration: Diverse temperature requirements for bioreactors, biological samples and laboratory consumables

• Precise process cooling: Gentle heat exchange, minimal temperature fluctuation and stable protection for bioreactor process cooling without thermal shock

• Secure equipment backup: One-use-one-backup configuration to prevent shutdowns caused by single-equipment failure, ensuring 24/7 refrigeration demand

• Eco-friendly low-noise operation: Environmental protection, safety, and low noise aligned with the high-end positioning of Guangzhou Bio-Technology Park

Targeted Solutions

Adhering to the principles of high quality, reliability and long service life, kendall Refrigeration selects world-leading refrigeration equipment and adopts a combined technical approach to ensure system stability and durability from the source. Each core need was addressed with a targeted solution:

Refrigeration Host System - Bitzer Compressors

High-quality Bitzer compressors are used for both cold storage and chiller units, offering high refrigeration efficiency, stable operation, low noise and low failure rates for continuous long-term use. Rationale: bio-pilot platforms cannot tolerate frequent compressor downtime; Bitzer’s high efficiency, stable operation and low failure rate match this need precisely, providing a continuous and reliable cold source for 24/7 operation.

Evaporation & Temperature Control - Bohn Air Coolers

Bohn air coolers are installed, providing high heat exchange efficiency, uniform air distribution and stable defrosting to ensure even temperatures throughout the storage space. Rationale: biological reagents, consumables and samples demand extreme temperature-field uniformity; any local difference risks sample degradation. Bohn’s uniform airflow characteristic solves this challenge.

Chilled Water Circulation - Grundfos Pumps

Grundfos pumps are selected for smooth operation, low energy consumption and long service life, perfectly matching chillers to maintain stable ethylene glycol circulation. Rationale: the glycol system requires precise supply temperature of -3°C and return temperature of +1°C with optimized flow and load matching; Grundfos’ reliable performance ensures maximum heat exchange efficiency.

Dual-System Architecture - Direct Expansion + Secondary Coolant

The system uses dual modes: R404a direct-expansion supply for cold storage, featuring fast response, high efficiency and precise temperature control; and ethylene glycol chilled water indirect cooling for bioreactor process cooling, delivering gentle heat exchange, minimal temperature fluctuation and stable protection for core equipment and processes without thermal shock. Rationale: this combined approach satisfies diverse temperature requirements for both storage and process cooling in one integrated system.

One-Use-One-Backup Redundancy - 24/7 Operation

The ethylene glycol chilled water system is fitted with two independent chillers operating separately and serving as backups for each other. Chilled water pumps also adopt a one-use-one-backup configuration. Rationale: this effectively prevents shutdowns caused by single-equipment failure, ensuring continuity for pilot experiments and production to meet the 24/7 refrigeration demand of bio-research scenarios.

Eco-Friendly Refrigerant - R404A

The entire system uses R404A eco-friendly refrigerant, meeting national environmental and safety standards. It delivers stable refrigeration performance, is environmentally friendly, and adapts to both low and medium-low temperature working conditions, balancing efficiency and safety. Rationale: eco-friendly refrigerants and high-efficiency systems ensure energy saving and low noise, matching the high-end positioning and environmental requirements of Guangzhou Bio-Technology Park.
