MoreWe design and build cleanrooms in full compliance with ISO 14644 and related international standards. We can provide third‑party test reports, validation documents, and material certificates so you can show clear proof to auditors, customers, and regulators.
Yes. We’re a turnkey supplier: concept design, layout, HVAC, purification equipment, modular panels, doors, windows, flooring, onsite installation, testing, and commissioning—all done by one team, with one project manager, and clear timelines.
We focus on system design + quality materials + strict testing. After installation, we do on‑site particle count, airflow, pressure, temperature and humidity tests. We also give maintenance guidelines and can offer periodic re‑testing and service if needed.
We work with pharmaceuticals, biotech, medical devices, electronics, semiconductors, food & beverage, and labs. Each industry has different regulatory and process needs—we customize the layout, materials, and air system based on your specific application.
We use traceable, certified materials (like FM‑approved or fire‑rated panels, brand‑name filters and fans). Every batch is checked against specs, and key parts have inspection reports and certificates. This reduces risk of failures and helps with your audits.
It depends on size, class, and complexity, but as a rough guide: small modular cleanrooms may take a few weeks; medium projects often take a couple of months from final design to handover. Once we know your requirements, we can give a clear schedule and milestones.
