7-Step Process for Surveying and Constructing a Cold Storage Facility in Nam Dinh
To ensure precise progress and the highest fire safety acceptance standards for industrial construction projects, Tan Long applies a rigorous 7-step EPC general contracting process:
- Step 1 – Receiving and surveying the site within 24 hours: Tan Long's mechanical and electrical engineers personally visited Giao Thuy, Hai Hau, and Rang Dong Industrial Park to measure the ground elevation, 3-phase power supply, and soil characteristics.
- Step 2 – Calculate the thermodynamic cooling load: Using specialized software, we accurately calculate the required refrigeration capacity based on the daily inventory volume, the required temperature range, and the ambient outdoor temperature in Nam Dinh.
- Step 3 – Design 2D/3D drawings & combined perspective views: Provide floor plan drawings showing the layout of the panel enclosure, compressor unit location, refrigerant piping, safety valve system, and condensate drain system.
- Step 4 – Component fabrication at Tan Long Factory: We directly manufacture B1/B2 fire-resistant PIR panel enclosures with Camlock fasteners, fabricate T-Light 304 stainless steel sliding/hinged cold storage doors, and assemble PLC control cabinets.
- Step 5 – On-site installation and completion: The team of professional pressure pipe welders proceeded to construct the warehouse shell, install the compressor system, evaporator, and run the control signal wiring.
- Step 6 – Vacuuming, pressure leak testing & refrigerant charging: Test the pressure using dry nitrogen gas at 25-28 bar to ensure there are absolutely no gas leaks before running a cooling load test.
- Step 7 – Acceptance, Handover & Transfer of Operational Technology: Hand over the CO/CQ documents proving the origin of the equipment, instruct technical staff on SCADA operation, and activate the 24/7 warranty mode.
