Indoor unit duct type allows concealed installation in suspended ceilings and air distribution channels, air ducts. These systems are often used in areas where design is important, since the block itself is not visible in the room, but only the lattice diffusers or air distribution visible to the eye. Blocks channel-type medium pressure can be connected to ducts (channels) with a length of 3.7 m. As a rule, such a solution is sufficient for a single storey cottage or a large store room with separated rooms, a small distance between them. Sometimes in the interiors of shopping malls and cafes such systems are left open, underscoring the utility and adaptability interiors. All indoor units are equipped with channel remote control supplied, wired remote can be ordered as an option.
