Hitachi 5 Ticks Inverter Multi Split System with FrostWash® System 3 Aircon

Our R32 wall mounted inverter series demonstrate Hitachi’s technological innovation with patented FrostWash® technology for clean and healthy air It is also designed for use in tropical climate and equipped with Hitachi’s DC compressor which offers efficient performance during periods of extended operation.


FrostWash® technology

A revolutionary new self-cleaning technology so you can now depend on a cleaner, fresher unit all year around. This unique, patented technology eliminates mould, dust and bacteria that has buit up on the heat exchanger’s surface by trapping and freezing these particles in ice, which melts and is then flushed out safely.

A self-cleaning technology AC automatically cleans the filters for the most hygienic air on the market.

Air Sleep Timer

Our smart technology monitors your surroundings across multiple nights, optimising conditions for deep sleep. Wake up feeling refreshed and ready for what’s ahead!

Freeze. Melt. Clean. Our “coolest” technology keeps the inside of your air conditioner cleaner and fresher

FrostWash® removes hidden impurities, safely and effortlessly, and improves your indoor air quality.

Our FrostWash® technology minimizes the amount of dust, mold and bacteria that build up on your air conditioner’s heat exchanger. FrostWash® can reduce the presence of these impurities inside your unit by up to 93%**of bacteria and mold and 99.99%* of viruses, promoting healthier air and keeping unpleasant odors at bay.

To do so, FrostWash® traps the dust and dirt that lands on the heat exchanger by freezing it in the moisture that’s generated during normal operation. The frost is then thawed and flushed hygienically out the unit, carrying the dust, mold and bacteria with it.

FrostWash® removes and prevents bacteria and mold from accumulating in the unit, as well as disease-causing viruses. Through testing and research, this cleaning process was proven to successfully remove 99.9%* viruses. The air-borne bacteria, viruses and other dirt particles are trapped in ice and then flushed out, sterilizing the air.

 *Tested by Kitasato Research Center for Environmental Science. Test No. 2020_0386. Suppress Virus effect observation test by operating FrostWash®. Test was conducted with E.Coli and operating FroshWash™ for 280 continuous minutes.
** Tested by Kitasato Research Center of Environmental Science. Test No. 2017_40194: antibacterial & anti-mold effects when operating FrostWash® four times.



  • FrostWash: A state-of-the-art self-cleaning technology for cleaner and fresher air. This unique technology eliminates mould, dust and bacteria that has built up on the heat exchanger’s surface by trapping and freezing the impurities in ice, which then melts and flushes out safely.
  • Freeze: Frost is created as your unit uses dew from collected air moisture to cover the heat exchanger while it cools down to a maximum of -15C
  • Melt & Dry: Accumulated frost then melts and washes away dust attached to the heat exchanger.
  • 3D Airflow
  • Timer
  • Powerful Mode
  • Auto Restart Function
  • Eco Mode: The Vector DC Inverter System gives you reliable performance even in unstable power settings. It features a microchip that monitors compressor behaviour and current flow conditions, adjusting compressor rotation accordingly. With a smooth compressor operation, Vector DC Inverter is more energy efficient compared to non-inverter systems.
  • Smart Control (Optional)
  • PM 2.5 Wasabi Air Purifying Filter: Our PM 2.5 Wasabi Air Purifying Filter removes 99% of microscopic 2.5 m particles and is proven to be antibacterial, antifungal, anti-allergen, and have deodorising properties. When combined with the Nano Titanium Stainless Pre-filter, it provides the room with fresher and healthier air.
  • Nano Titanium Stainless Pre-Filter: The anti-static properties of stainless steel attracts less dust compared to filters made out of plastic material. A single wipe without water is all that is required to remove dust from the filter. It is also more durable and easier to clean.
  • Fireproof Electrical Enclosure: The fireproof electrical enclosure ensures safety and removes the possibility of a fire. A 100% metal housing seals tightly. Users need not worry about fire or safety hazard, instead enjoying cool comfort and peace of mind.
