Maestro is a high-static ducted fan coil unit designed for chilled water systems.

Maestro MTL fan coil units are available in 7 sizes for built-in installation or for connection to duct systems. They offer compact dimensions, quiet operation and high available static pressure (up to 160 Pa for sizes 1–5 and up to 250 Pa for sizes 6–7). They come standard with a 4-row heat exchanger, with the option of a 3-row version or additional coils for 4-pipe systems. They are ideal for climate control in small and medium commercial or sports facilities, as well as large public spaces, integrating seamlessly with typical suspended ceiling systems.

High available static pressure up to 250 Pa
2-year warranty
Complete range of accessories for any installation
Wide selection of individual and central control options
Top-quality, durable materials
Option to connect ductwork

High-static ducted 2- and 4-pipe fan coil unit (up to 250 Pa) with an asynchronous motor
