When you check out the new Hitachi air conditioning range from this well-regarded high-tech manufacturer, you just know that it has just taken energy efficiency on to another level. Saturn Sales is a leading supplier of the Summit and S-Series Hitachi heat pump models. As well as being kind to the environment, these Hitachi air conditioners are also highly economical too. You will be able to choose between the latest wall mounted systems which contain Hitachi’s renowned inverter and compressor technology, ensuring that only the minimum amount of power is consumed while the unit cools or heats a room. The latest range of Hitachi summit air conditioners and heat pumps such as the Hitachi RAK-35PED offer a host of new features such as a sleep timer, weekly timer and eco function to ensure the systems runs in the most economical way to provide climate control. For larger rooms up to 50 square metres we would recommend the RAK-50PED model. There is also a new wall mounted performance range which has an increased number of features and starts with the Hitachi RAK-18RPD model. Often people wish to have a heating only function, so on this range the system can be locked so it will only provide heating and not air conditioning. Other features of the performance range include a built in infra-red human movement sensor to optimise running conditions of the systems. Another plus point with this wall mounted range of air conditioners and heat pumps from Hitachi is that they use the new R32 environmentally friendly refrigerant gas.
