Engen Inverter Air Conditioners Series
Expandable Inverter Air Conditioners
Expandable Inverter ACs can increase their compressor’s rotation per minute (RPM) from the standard rated RPM, as and when required, according to the actual ambient conditions outside and load requirement inside the room. Its technology stems from our Tropical Inverter Technology that uses Seamless Cascade Vector DC Inverter System which gives better performance than any other non-tropical Inverter AC.
