1. Client Objectives & Stringent Technical Requirements
For the Meito Vietnam Co., Ltd. (Meito Group Japan) 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 -20°C to -25°C (Deep freezer) & 0°C to +5°C (Chilled sorting buffer) 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 Central NH3 (R717) Station - 4,500 kW Cooling 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.
