The type dimension of the Cleanroom HVAC System market is divided primarily into split‑air, recirculation, ducted, portable and modular configurations. Split‑air units, which combine external cooling with internal heat recovery, dominate the high‑capacity segment because they support large‑scale facilities such as semiconductor fabs, contributing roughly 40 % of total equipment spend. Recirculation systems, characterized by closed‑loop airflow and high‑efficiency filters, are favored in pharmaceutical and biotechnology plants where contaminant control outweighs energy cost, accounting for about 25 % of the market. Ducted solutions, integrated into building infrastructure, capture mid‑range projects that require uniform temperature distribution across multiple cleanrooms, representing 20 % of revenue. Portable units, offering rapid deployment for temporary or expansion projects, hold a niche 8 % share. Modular designs, which combine prefabricated components for scalable expansion, are emerging in fast‑growth sectors and currently generate 7 % of sales. Collectively, these type categories define the overall market size by aligning system architecture with facility scale, energy efficiency targets, and regulatory stringency.
