The Maestro MTL ECM fan coil units are designed for use in chilled water systems

The Maestro MTL ECM fan coil units are designed and manufactured for built-in installations, suspended ceilings, and ducted systems in residential, commercial, and sports buildings. They are characterized by compact dimensions, quiet operation, and an attractive price-to-performance ratio, achieving high airflow rates and an available static pressure of up to 160 Pa (sizes 1–5) and 240 Pa (size 6). Thanks to the ability to smoothly regulate airflow, the fan coil units provide precise control of environmental conditions and minimal energy consumption.
