Up to 48 indoor units can be connected to the largest outdoor unit. The range includes 15 exposed and concealed models, in several capacities. A choice of 77 indoor units is available.
KX6 heat pump systems operate with 2 inter-connecting pipes, commonly referred to as a '2-pipe system'.
These systems provide either a heating or cooling operation to all indoor units. They are suitable for a wide range of applications from an individual apartment (with the KX6 compact 1/phase system) to an entire multi-storey building, including where there are significant open plan areas to be controlled.
The range starts with a compact, 1 phase model with 11.2kW cooling capacity, up to the largest capacity single outdoor unit in the industry (24hp) with 68.0kW cooling capacity. Outdoor units can also be “twinned” providing up to 48HP/136.0kW on a single system.
The KX6 range has a total piping length of 1000m and the furthest indoor unit can be connected up to 160m from the outdoor unit.
