Product Description
Hitachi R32 Summit RAC-50WEF 5kW Inverter Split Wall Mounted Air Conditioning System

Hitachi is one of Japan's giant electronics conglomerates renowned for quality, their air conditioning and heat pump systems are no exception. The Hitachi Summit range offers energy efficiency with many other manufacturers using their efficient inverter driven compressors (outdoor units). Hitachi has pioneered energy efficient systems with the outdoor unit using Hitachi’s pioneered PAM inverter drive system.  Another major benefit of the Summit series is pipework lengths between the indoor and outdoor unit of at least 20 meters, giving installation flexibility.

The Hitachi Summit range offers a stylish new flat panel front design to compliment any room. With compact indoor units and low noise levels, the Summit is a versatile unit suitable for many different applications. 

Product Features
  • Seasonal efficiency: all Hitachi RAC units offer high seasonal efficiencies
  • Volt free contact: Volt free contact of the air conditioning system - can be used to turn the unit on/off remotely after receiving a signal such as a key-card, door or window switch, specifically uselful in hotel rooms to prevent unnecessary use (accessory SPXWDC3 is required)
  • Super quiet: Low levels courtesy of low fan speeds (21 dB(A) in SL mode)
  • Guaranteed operation: in heatng mode down to -15°C
  • Suitable for BREEAM assessed buildings: heating mode lock suitable for BREEAM assessed buildings where cooling mode is not accepted or required
  • Compact units: 280x780x218 indoor units are common across the entire range which allow for easier integration
  • Remote control: user friendly, easy to use infra-red remote control
  • DC Inverter: as the pioneer of DC Inverter drivern units, Hitachi outdoor units boast significant advantage of all DC Inverter driven compressors and fans allowing for complete control of capacity and temperature
