Heat installed almost unnoticeably

Air-to-air heat pumps of the SEZ-KD series are almost unnoticeable, because indoor units are installed into channels under the ceiling. Only an air intake grille and air outlet openings remain visible, therefore, the interior of the premises is not defaced. Compact indoor units occupy little space and can be installed in the premises with low ceilings. This is an excellent choice for the home, when you do not want or it is not possible to install wall-mounted heat pumps or heat pumps of another type.

In order to satisfy heating/cooling needs of the premises more appropriately, three fan speed settings and four static pressure levels (5, 15, 35 and 50 Pa) are available to choose from. Condensate pumps are also available to be chosen as accessories.

Combined heating/cooling and ventilation system

Ducts of a heating system can be used for ventilation of premises with a MITSUBISHI ELECTRIC LGH-RVX ducted recovery ventilator. This is an extremely comfortable system enabling efficient heating, cooling and ventilation of all the desired premises at the same time.
