1. Client Objectives & Stringent Technical Requirements
For the C.P. Vietnam Corporation (Charoen Pokphand Group) facility, uninterrupted cold chain integrity demands continuous 24/7 thermodynamic stability. Key design criteria addressed by Tan Long's engineering teams include:
- Pinpoint Thermal Stability: Operating within -25°C (Meat freezer storage) & 0°C to +4°C (Fresh meat processing) with strict temperature tolerances within ±0.5°C to prevent product shrinkage or crystallization.
- Energy Efficiency Optimization: Deploying variable-frequency screw compressors coupled with smart floating head pressure control to curb peak-hour power tariffs.
- Zero Compromise on Refrigerant Safety: Utilizing NH3 (R717) & Safe Secondary Food Glycol paired with automatic shut-off valve manifolds and multi-point ammonia leak detection.
- Long-Term Structural Durability (25+ Years): High-density flame-retardant sandwich panels and floor frost-heave mitigation systems withstanding heavy forklift traffic.
2. Advanced Thermodynamic Solutions Delivered by Tan Long
To fulfill these rigorous expectations, Tan Long deployed an integrated thermodynamic architecture:
- Centralized Compressor Stations: High-efficiency Japanese/German industrial screw compressors equipped with stepless slide-valve capacity modulation.
- In-House Fabricated Pressure Vessels: High-pressure liquid receivers, surge drums, and oil separators built at Tan Long's manufacturing plant under ASME and TCVN standards.
- Induced-Draft Evaporative Condensers: Closed-circuit cooling towers cutting water consumption by over 30% compared to traditional open cooling towers.
- SCADA IoT Automation: High-speed PLC controllers transmitting real-time thermodynamic metrics to control rooms and mobile devices with automatic anomaly alerts.

Technical Project FAQs
1. What scope did Tan Long execute for C.P. Vietnam in Cu Chi?
Designed the dual-stage compressor station, glycol distribution network, fire-resistant PIR cleanroom envelope, and smart SCADA management room.
2. Why combine both ammonia and glycol circuits?
Ammonia is confined strictly to the outdoor machinery room for peak thermodynamic efficiency, while harmless glycol circulates through meat processing halls, eliminating food contamination hazards.
