Vector DC Inverter technology

Our Cascade Vector DC Inverter System is equipped with a microchip to control the speed of the compressor. A split rotor with displaced electrical poles enables electromagnetic noise suppression and optimizes low-speed energy-efficiency. ​

With inverter technology, an air conditioner cools with maximum capacity at start-up, then automatically slows down and operates at a minimal capacity to maintain room temperature at a comfortable level. Non-inverter models can only operate with simple on-off controls. Trying to maintain the desired temperature by repeatedly switching power on and off consumes much more electricity and results in bigger temperature fluctuations.

3 air purifying features:

FrostWash cleans the heat exchange coil

FrostWash cleans the heat exchange coil

Our renowned FrostWash technology activates to remove the dirt and mold accumulated on the indoor unit’s heat exchanger coil. ​

It freezes the heat exchanger down to 15ºC to trap pollutants and dust in the ice and then melts them to flush them away.​

FrostWash provides dual benefits:​

  • Sanitizing effects: 99% viruses eliminated [1], 99% bacteria eliminated[2], 95% mold reduction [3]

  • Preservation of airflow capacity: Our tests show that systems with FrostWash are 3×better at maintaining airflow performance than those without this technology[4]
