About Lg's Multi Inverter Air Conditioning Unit

The Lg multi split air conditioning inverter heat pump units make it possible to have multiple combinations of different indoor units with different capacities with the advantage of a space saving outdoor condensing unit. The latest Lg Inverter heat pump technology allows greater performance, lower sound levels, lower energy consumption and operates at optimum performance in a rapid and uniform manner until the temperature reaches its optimum set point. The DC Inverter multi split heat pump outdoor units are more efficient than their predecessor and Lg air conditioning's renowned inverter technology is an innovative, energy-efficient feature that automatically adjusts the unit’s power to maintain room temperature across all the indoor units connected, rather than repeatedly starting and stopping the compressor. The patented Gold Fin™ process on the outdoor condensing unit is standard on the LG multi outdoor units and is an anti-corrosion coating that forms a protective shield against the elements to increase the product lifetime. As there is no need to install a large number of outdoor units, the outside aesthetics of the building are virtually unaffected, furthermore, the outdoor units offer great location flexibility to ease the installation.

Wall Mounted Units:

The new design Standard Plus wall mounted indoor units are artistic, thinner and quiet while offering a NATURAL ENZYME FILTER Which destroys funghi, bacteria and viruses combined which combined with the main PHOTOCATALYTIC WASHABLE DEODORIZING FILTER provides healthy clean air for the occupants. The Libero "Night silent" operation feature can remain engaged for a pre-set number of hours, switching on at the day's peak temperature and then returning to normal operation. Dehumidification mode accurately senses the room's temperature and controls humidity without over cooling while increasing the vane angle preventing over cooling. The Jet Cool operation which has always been a feature on Lg's units and can cool a room to 18°C in a rapid time with a high power mode. This is ideal when fast cooling is required.
