A Energy Rated Product   

The Hitachi air conditioning RAI Mini-cassette range are highly economical and environmentally friendly. Using the latest compressor and inverter technology keeps power consumption to a minimal, but at the same time providing powerful cooling and heating. All Hitachi’s air conditioning units offer high seasonal efficiencies, achieving high seasonal performance SCOP A 3.8 and SEER A 5.2. ​​The compact dimensions of the mini cassette model (285 x 580 x 580) are common across the entire range and allow for easier integration.

Enhanced inverter performance and system performance are achieved by the addition of a ‘Direct Current’ drive compressor, resulting in up to 10% more efficient than standard 'AC' (Alternating Current) Systems. The variable speed compressor (inverter) enables the system to rapidly reach the desired room temperature setting. Once the desired room temperature has been achieved the compressor rotation peed is reduced, saving up to 30% in energy usage (when compared to standard fixed speed systems).
This unit is ductable, meaning airflow can be ducted to another area in the room or another small area, the unit has its own internal drain pump to remove accumulated condensation water from the drain pan even while it is operating. A float switch monitors the water level and automatically activates the pump as necessary. The indoor unit fits into 60cm x 60cm ceiling module. With it’s the compact design the 60cm x 60cm ceiling unit neatly fits inside a standard ceiling module which minimises the installation work.

Volt Free control of the air conditioning system option, used to turn the unit on/off remotely after receiving a signal such as key-card, door or window switch, specifically useful in hotel rooms to prevent unnecessary use. Accessory SPX WDC3 is required.
