The voltas product is good this ac designed only for the medium sized rooms it comes with 1.5 ton capacity it equipped with copper tubes and blue hydraulic aluminium fins this ac can easily resist corrosion. In these ac used in copper coil compared to aluminium coil it provide better cooling speed and higher energy efficiency, easy maintenance and lower repair cost it can use any other appliances required electrical socket it can be used in any other stabilizer it must be 2.7 Kva capacity. I have an minor issues in the voltas some days of installation the noise level is slightly high compared to other products.
