Why it exists
The volume 1.5 tonne: convertible, quiet from 38 dBA, ISEER 4.35.
Why it is built this way
ISEER 4.35 · 3 Star
01
Inverter compressor
The compressor modulates its speed rather than switching hard on and off, so the room holds temperature instead of oscillating around it — and the draw drops once the set point is reached.
02
R32 refrigerant
Charged with 550 g of R32. R32 carries roughly a third of the global warming potential of R410A and transfers heat more efficiently at the same charge.
03
Built for Indian supply
Rated to operate from 145 V to 285 V. Indoor noise from 38 dBA.
