Verdict

The Olimpia Splendid Aryal S1 E Inverter 10 C (Model OS-K/SEAPH10EI) is a high-wall mono-split heat pump air conditioner delivering a cooling capacity of 10,000 BTU/h (2.64 kW) and a heating capacity of 2.93 kW. It utilizes eco-friendly R32 refrigerant gas and features advanced inverter technology, yielding high seasonal efficiencies with an A++ energy rating for cooling and A+ for heating. Key characteristics include multi-stage Air Quality filtering (anti-dust, activated carbon, and cold catalyst), an automatic Self-Clean evaporator cycle, and multiple operating modes like Dehumidification, Sleep, and Follow Me. Main pros consist of a low indoor sound power level of 53 dB(A) for quiet operation, a 30% reduction in energy usage compared to traditional models, and Golden Fin anti-corrosion protection on the outdoor coil. Notable cons are that the Wi-Fi USB adapter kit required for smartphone app control is not included out of the box and must be purchased separately.
