The new Hitachi 'S' Series range of split systems offers many innovative features, from enhanced energy efficiency, to airflow control and ultra-quiet operation. FrostWash addresses an issue that had long stumped the air conditioning industry - how to effectively and efficiently clean the inside of room air conditioning units.
With FrostWash, a revolutionary new cleaning technology, you can depend on cleaner, fresher air all year round.
When no motion is detected, the system cools the heat exchanger down to -15° C forming a thin layer of frost from the moisture within the air. While the frost is being formed, it lifts dust particles, mould and bacteria off the heat exchanger and traps it.
Once an adequate layer of frost has been formed, the system melts the ice, flushing away the trapped dust particles, mould and bacteria hygienically through the drain pan.
The unit then thoroughly dries the surfaces inside the unit before resuming normal operation. A clean heat exchanger keeps your unit operating at optimal efficiency and keeps the air in your home fresher and cleaner.
Providing your indoor environment with fresher, cleaner air.
FrostWash achieves a 91% reduction of bacteria and 87% reduction of mould in your unit*.
For the purest air quality, the S-Series also features an additional Nano-Titanium pre-filter as well as the unique Titanium Wasabi Air Purifying filter.
* Feature introduction based on RAS/RAC-S35YHAB. Tested by Kitasato Research Centre of Environmental Science. Test No. 2019_0154. (Reduction effects of bacteria and mould were observed by operating Frost Wash once.)
The S-Series comes with a suite of unique features such as built-in Motion Sensor with motion detect eco mode, Eco Sleep mode, leave home function and weekly scheduling capabilities.
Motion-detect Eco Mode allows the unit to adapt its temperature settings depending on people’s absence or presence - saving you power.
Premium S-Series Hitachi Wall mounted split systems have increased energy efficiency and improved energy star ratings for even more power-saving operation.
The Eco Motion sensor can automatically detect if there are individuals occupying a room and if the room becomes vacant, your air conditioner will adjust the temperature accordingly to conserve energy.
FrostWash mode can be activated to keep the heat exchanger clean and reduce power usage even further.
The S-Series comes with a stylish wireless controller which has a built-in feature – Power Consumption Tracking.
Monitor your air conditioner’s power usage, ensuring that there are no surprises when the electricity bill arrives.
Installing the optional airCloud Go wifi controller module allows you to control your wall-mounted system using your smartphone or tablet.
Operate your system from home or remotely, adjusting temperature, fan speed and setting custom schedules.
