Verdict

The De'Longhi Pinguino PACEX100 Silent is a 3-in-1 portable air conditioner, dehumidifier, and fan featuring a 10,000 BTU (2.5 kW) cooling capacity that efficiently handles room volumes up to 110 m³. Key technical highlights include an outstanding A++ energy efficiency rating, an eco-friendly R290 refrigerant gas, a 700 W power consumption, a 32L/24h dehumidifying quotient, and a maximum airflow of 350 m³/h managed via a digital LED control panel with Real Feel technology. The primary pros are its highly efficient operation, low running costs, specialized Silent Technology keeping noise between 49–53 dB(A) sound pressure, and a motorized swing flap for even air distribution. Main cons include a high retail price, lack of Wi-Fi or smart-home connectivity, a bulky 30 kg weight, and an LED front display screen that cannot be turned off during night mode.
