A major food export enterprise in Hai Duong, Vietnam required an immediate fit-out of a 2,800 m² facility conforming to international HACCP, ISO 22000, and US FDA environmental standards. The facility required 3 strict environmental zones: raw material prep (quasi-clean), continuous baking & cooling (Class 100,000 / ISO 8), and sterile inner packaging (Class 10,000 / ISO 7).
The Operational Bottleneck: Local Vietnamese engineering contractors quoted 6+ months for imported equipment with a 35% broker markup, but lacked in-house HVAC balancing expertise to guarantee positive differential pressure cascades (+15 Pa) against tropical high-humidity exterior air.
BESTCLEAN's Dual-Engine Solution: All core equipment (air showers, pass boxes, AHU coils, doors, panels) was pre-fabricated in our Zhangzhou mother plant in 18 days, shipped via Xiamen Port direct to Haiphong Port (5 days ocean freight), and assembled on-site under 2 senior dispatched BESTCLEAN project directors.
All photographs captured on-site during installation and final validation handover:
Airtight cleanroom corridor separating baking and cooling lines. Flush double-glazed viewing windows with silica desiccant to withstand tropical humidity.
Automated conveyor line operated under H13 ceiling HEPA laminar flow diffusers with constant positive pressure prevent airborne microbe ingress.
High-frequency forklift and hand-truck transfer portal fitted with heavy-duty SUS304 double-swing impact doors and blue epoxy anti-slip floor.
Integrated airlock entrance pairing a single-person automatic air shower with a motorized roll-up cargo airlock for complete cross-contamination defense.
Pre-entry gowning station featuring hands-free sensor SUS304 sinks, knee-operated soap dispensers, and automated high-speed hand dryers.
Dedicated rooftop mechanical room housing modular AHU units with DX condensing sets delivering 22±2°C temperature and 50±5% RH year-round.
