Digital inverter compressor works longer, quieter and uses less energy. Digital inverter technology automatically adjusts the compressor speed in response to cooling demand across 7 levels. It uses less energy, minimises noise and reduces wear and tear for longer-lasting performance. Stabilizer free operation, protection from voltage fluctuation, its stabilizer free operation means it works very steadily and reliably and prevents electrical damage or shorting if there are any voltage fluctuations. If it increases too much it automatically cuts the power.
