Thai Corp Ichiban Tofu Controlled Cold Storage Facility

Tan Long engineered, fabricated, and installed the NH3 refrigeration system for Thai Corp at the ICHIBAN manufacturing plants in Hanoi and Tan Binh (HCMC). Delivering 4 equipment packages, including pressure vessels manufactured at Tan Long's works, it provides precise chilled preservation for premium fresh tofu.

Project Dossier: Thai Corp Ichiban Tofu Controlled Cold Storage Facility represents a turnkey EPC industrial refrigeration achievement delivered by Tan Long Refrigeration & Electrical Engineering JSC. Encompassing thermodynamic modeling, in-house pressure equipment manufacturing, and complete on-site commissioning, the facility meets strict global food safety codes (HACCP, ISO 22000, FDA) with an engineered lifespan exceeding 25 years.
Client / Investor: Thai Corp International Co., Ltd. (Ichiban Foods)
Facility Location: Tan Binh District, HCMC & Hanoi Branch
Scale & Capacity: Controlled cold storage for pasteurized food & Ichiban fresh tofu products
Design Temperature: +1°C to +5°C (Pasteurized chill preservation)
Key Engineering Highlight: Fresh tofu is exceptionally sensitive to thermal fluctuation. Tan Long's precision cooling maintains a steady +2°C environment with balanced humidity, extending natural commercial shelf life without preservatives.

1. Client Objectives & Stringent Technical Requirements

For the Thai Corp International Co., Ltd. (Ichiban Foods) 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 +1°C to +5°C (Pasteurized chill preservation) 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 Industrial NH3 with Precision Air Coolers 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.
