  • TechnologyDesigned for high Ambient Conditioners
  • TechnologyWorking upto - 48° C
  • TechnologyNew-type Scroll Compressor
    Uses a high-pressure scroll-type compressor with improved
    quality and reliability of compressor mechanism materials.
  • Technology DC Compressor
    By using DC, the performance is improved at around 30-40 Hz
    where the operation time of the invertor compressor is longest.
    Also, to suppress electromagnetic noise interference and
    achieved low noise, the rotor has been divided into two and the
    electric pole displaced.
  • TechnologyHigh-performance Heat Exchanger
    A new high-performance heat exchanger has been developed with
    improved piping arrangement.
  • Technology Self-diagnostic System
    The self-diagnosis result is shown on a digital display via control
    from either a remote control (relating to indoor units) or one of the
    outdoor units. This air conditioning system can be checked for
    operation even through the printed circuit board in the outdoor
    unit, allowing you to carry out inspection work and/or take
    remedies more quickly and correctly.
  • TechnologyCompact Size And Lightweight
    Outdoor units have become even more compact and lightweight.
    Outdoor units require a 40% smaller installation space compared
    to conventional types and weigh about 25% less. They are easily installed in cramped spaces and
    are small enough to be carried by ordinary elevator to the
    installation location.
  • TechnologyThe Quietest In The Industry
    A new stream fan and enilarged bell-mouth is used in this series.
    The fan rotatIon control has been changed to PWM (Pulse Width
    Modulation type. These improvements contribute to the quietest
    operation (58 dB). Furthermore, specific attention is paid to
    nighttime operation. If the outdoor temperature does not exceed
    30 degree Celsius during cooling, this model will operate in night-
    shlft mode by night-shift setting, enabling it to run at low noise
    level of 53 dB.
  • TechnologyEnergy Saving Control
    The compressor can be operated by optimizing control over its
    service frequency depending on the capacity of indoor units.
    Optimizing reduces the power consumption, achieving 81%
    annually.
  • Technology Greater Flexibility Of Installation
    The actual piping length has been extended from 120m to 250m.
    The distance between the first branch unit and terminal unit can
    be 40m. Hence, installation is flexible.
