Introducing Frost Wash Technology

A revolutionary new cleaning technology, you can depend on for cleaner, fresher air like never before.

Self-Cleaning Technology

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 then 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 not only keeps your unit operating at optimal efficiency but also keeps the air in your home fresher and cleaner.

Long Lasting Hygienic Air

Providing your indoor environment with fresher, cleaner air.

Frost Wash 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.)
