DELLA 4.41 Ton 53,000 BTU 17 SEER2 Central Ducted Two-Stage Inverter Heat Pump Split System - Multi-Position - R-454B

Built for larger homes and demanding cooling needs, this 53,000 BTU ducted central AC system provides reliable year-round comfort with R-454B refrigerant and 17 SEER2 performance supported by inverter technology. The heat pump continues operating in temperatures as low as –5°F / –20°C, delivering steady heating during colder weather.

A dual-stage inverter rotary compressor adjusts output automatically to keep temperatures consistent across spacious rooms and multi-room layouts. With RS-485 and 24V control compatibility, the system works smoothly with a range of central AC configurations. High static pressure (200 Pa) and 7 adjustable fan speeds help push strong, balanced airflow throughout multi-room or multi-floor spaces.

Optional enhancements include a wired controller for stable wall-mounted control and a 10kW heat kit for households in extremely cold climates. These options allow you to customize the system based on comfort preferences and regional conditions.

The indoor unit supports both vertical and horizontal installation to fit a variety of layouts. Note: Professional installation is required; not suitable for DIY. Electrical specs: Indoor unit max fuse 15A, outdoor unit max fuse 60A.
