MULTI V Water IV has high efficiency inverter scroll compressor with frequency range from 15Hz to 150Hz. It improves performance with low vibration and reduced noise.
  • The highlighted red bar with two white dots represents the positions of 20 Hz and 140 Hz.

    Extended Compressor Speed

    Rapid operation response increases part load efficiency.

  • Two black LG variable frequency compressors are placed side by side. Both tanks are filled with yellow oil up to 1/5 of their capacity.

    Smart Oil Management

    Oil recovery occurs only when required and this enhances compressor reliability and user comfort.

  • Yellow oil is circulating between the central LG variable frequency compressor and the smaller reservoir located on the right.

    HiPOR™

    Energy loss is eliminated by returning oil directly to compressor for increased efficiency.

  • On the left, there are 4 outdoor units with a capacity of 10HP from brand B, while on the right, there are 2 LG Multi V Water IV outdoor units with a capacity of 20HP.

    Compact Size

    The optimal design of the compact, lightweight outdoor unit enables double stacking, which results in 50% savings in installation space.
