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.

Our ACs with Tropical Inverter Technology have a unique variable speed tropical compressor that varies its RPM by adjusting the power supply frequency of its tropical compressor. This is achieved by Seamless Cascade Vector DC Inverter System that comes pre-installed with a micro computer which controls its rotation, providing cooling solutions as per the room’s requirements. Thus, giving it an edge over conventional Inverter ACs.

Specially designed advanced microcontroller checks indoor and outdoor condition, and varies compressor speed seamlessly, thus offering uninterrupted cooling.

Hitachi's intelligent Penta sensor technology with its advanced microcontroller offers perfect cooling even in extreme summer conditions, optimises cooling in load variation and protects critical components of the AC.
