Product Description

Hitachi S-Series RAK-25PSB 2.5kW 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.  

The Hitachi S-Series range is available in nominal cooling capacities 1.8kW to 3.5kW and excellent efficiency. With stainless steel components for purer air and an energy saving sensor, the S-Series has everything you need for efficient, pure cooling and heating. 

Product Features
  • High seasonal performance: SCOP A++ 4.7 and SEER A+++ 8.5
  • 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 
  • Stainless clean: the components in the indoor unit (including filter) are stainless steel for greater air quality
  • Energy saving sensor: this operates the unit depending on the presence or absence of people in the room 
  • Remote control: user friendly, easy to use infra-red remote control with 24hr/7 day timer as well as a weekly timer with up to 6 patterns
  • Leave home function: set the temperature to 10°C automatically when you are away for up to 99 days
  • 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
  • Heating/cooling only operation: 2 ways of setting room temperature display
  • Outdoor unit constant power: maintains a heated output up to -15°C even during the coldest periods
