Engineered for medium to large domestic spaces, the Electrolux ChillFlex Pro EXP34U338CW packs a muscular 12,000 BTU (3.4 kW) cooling capacity to rapidly overcome high ambient heat loads. Ideal for master bedrooms, open-plan dining rooms, or busy offices up to 36 square metres, this air conditioner balances robust power with Scandinavian design refinement. Built-in R290 refrigerant ensures minimal environmental impact alongside Class A energy performance, maintaining modest household running costs. The appliance features automated condensate recycling which recirculates moisture over the condenser, greatly reducing manual reservoir emptying. Users benefit from 3 fan speeds, automatic vertical oscillation louvers, an antibacterial filtration barrier, and an intuitive LED control module with remote operation. Pre-fitted robust castors and top side grips facilitate smooth repositioning, while the included window exhaust connector kit ensures quick venting through standard sliding or hinged windows.
