The ducted blower Split Systems of DXD-M/K series are the ideal solution for keeping the best comfort level in large-sized spaces as offices, shops, hotels or education facilities.
The range comprises 12 models from 75.000 BTU/h to 600.000 BTU/h and the systems are composed of one indoor unit connected to up to four outdoor units, depending on the cooling capacity required.
The systems operate with R410A refrigerant and feature Scroll compressor.
The units are designed for installation both in service rooms or built-in; the air ducts, totally hidden on the ceiling or on walls, provide the perfect comfort without compromising on the building architecture and design. Models over 125.000 BTU/h feature both horizontal and vertical air outlet, which can be chosen directly onsite, to allow the highest flexibility in installation.
The ducts ensure an even distribution of conditioned air to every corner of the room. Even multiple areas can be conditioned simultaneously just with one indoor unit.
The range is characterized by low-noise operation of both internal units and external units, thanks to the high level acoustic insulation.
