1. Client Objectives & Stringent Technical Requirements
For the New Era Cold Storage Joint Stock Company (NECS) 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 -40°C (Blast Freezing) • -20°C (Automated ASRS) • +5°C (Cool Zone) 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 Two-Stage NH3 • Japanese MYCOM Screw Compressors 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.
