The Sigma Air Conditioner has been designed from the ground up to be outstandingly efficient. Its uniquely triangular design has a wider intake, so more air can be drawn in. The improved width and angle of its outlet, extra v-blades and a bigger fan also ensure that air is cooled and expelled faster and further. So refreshingly cool air reaches every corner of your room without blind spots. The Sigma Air Conditioner features an energy-efficient Smart Inverter with EER 10.8. It can maintain the desired temperature without frequently shutting off and on, so it consumes up to 60% less energy. The Smart Inverter helps you to stay comfortable for long periods of time, while using the minimum amount of energy.
