Fan coil units (FCU) serve as core HVAC components delivering efficient water‑based cooling and heating for diverse buildings. Featuring high‑performance heat exchangers and low‑noise fan motors, they enable independent zone temperature regulation with flexible installation for concealed or exposed layouts. A boasting compact footprint, stable performance and easy maintenance, these units adapt well to new construction and renovation projects. Widely applied in hotels, offices, apartments and commercial premises, they support 2‑pipe or 4‑pipe hydraulic systems to match different climate requirements. Optimized airflow and energy‑saving operation help cut running costs while securing steady indoor comfort for residential and commercial HVAC projects.
