What Cleanroom Systems International does

Cleanroom Systems International B.V. (CSI) is a privately held Dutch specialty contractor headquartered in Drunen, Noord-Brabant, Netherlands, that designs, engineers, builds, and services modular cleanrooms. The firm develops and manufactures two proprietary building systems — the DFP80 Cleanroom Wall System and the DFC78-O Cleanroom Walkable Ceiling System — which form the technical core of its offering and are positioned as quickly installable, demountable, and reusable, supporting a "modular, circular, adaptable" construction philosophy. CSI complements these wall and ceiling systems with in-house HEPA/ULPA filtration, air-flow control, and custom gowning-room/changing-room design capabilities.

CSI operates a turn-key Design-Engineer-Build-Care delivery model, covering analysis, technical detailing, on-site installation, and post-delivery maintenance contracts for enterprise clients in semiconductor and high-tech, pharmaceutical, medical device, food and dairy, mechatronics, and aerospace end-markets. Pricing is bespoke and quote-based, with no public list pricing; sales run through direct consultative engagement (phone, email, multilingual Dutch/German/English website, and trade shows such as the Precision Fair 2025). The team is small (approximately nine employees including Director Sil Munsters, project managers, draughtsmen/calculators, and installation foremen), and the company is concurrently constructing a new, larger Drunen headquarters with 426 solar panels as of late 2025, signaling capacity expansion ahead of a 700+ m² cleanroom delivery at High Tech Campus Eindhoven scheduled for 2026.
