How each alternative compares
DELLA 27K BTU 2-Zone Ceiling Cassette
The Della 27K BTU 2-Zone Ceiling Cassette reduces total cooling capacity to 27,000 BTU/h while maintaining the same 22.5 SEER2 efficiency rating. It uses a 9K+23K zone split instead of the original 12K+18K configuration. This model keeps the identical 22.5-inch width and 9.63-inch height, ensuring it fits the same ceiling space. You trade 8,000 BTU of raw power for a potentially more balanced airflow distribution in smaller rooms. It remains a dual-zone ceiling cassette with similar commercial aesthetics. Choose this if your spaces are smaller and do not require the full 35,000 BTU output of the original unit. It offers comparable quiet operation and smart app control for precise zone management.
Cooper & Hunter 28,000 BTU 2-Zone Mini Split
The Cooper & Hunter 28K BTU 2-Zone Mini Split operates on a dedicated 230V electrical circuit, matching the voltage range of the original Della unit. It delivers 28,000 BTU/h total cooling, which is 7,000 BTU less than the original. This model features a 9K+18K zone split. Its indoor units are significantly larger, measuring 40 by 40 inches, compared to the original's 22.5-inch square footprint. This size difference may impact your ceiling layout options. It includes smart connectivity for remote control. Select this alternative if you need a 230V system but have the ceiling space for larger indoor cassettes. It provides strong performance for two rooms, though with less total cooling capacity and a different physical profile than the original Della cassette.
Della 34K BTU Dual Zone Concealed Ducted
The Della 34K BTU Dual Zone Concealed Ducted unit offers a different installation method. It is designed for hidden ducted setups rather than exposed ceiling cassettes. It provides 34,000 BTU/h cooling, slightly less than the original 35,000 BTU/h. The indoor unit is smaller in width at 27.5 inches but taller at 7.87 inches. It includes a condensate pump, which adds functionality for drainage in areas where gravity flow is difficult. This model retains smart app control and dual-zone independence. Choose this if you prefer a concealed look behind drywall or in a drop ceiling grid. It sacrifices the visible 360-degree airflow of the original cassette for a cleaner aesthetic and integrated pump, making it ideal for spaces where visibility of the unit is undesirable.
BRAVO 30K BTU 2-Zone Cassette
The BRAVO 30K BTU 2-Zone Cassette offers a higher efficiency rating of 23 SEER2, surpassing the original Della unit's 22.5 SEER2. It delivers 30,000 BTU/h total cooling, which is 5,000 BTU less than the original. The zone split is 9K+24K, providing more cooling power to one room than the original's balanced approach. The indoor units are larger, measuring 40 by 40 inches, requiring more ceiling space. It emphasizes precise smart zone control and energy savings. Select this alternative if energy efficiency is your top priority and you have the space for larger indoor units. It provides strong performance for two rooms with better efficiency, though with reduced total cooling capacity and a bulkier physical design compared to the compact original Della cassette.
Della 27K BTU Dual Zone Soft Airflow
The Della 27K BTU Dual Zone Soft Airflow Mini Split focuses on comfort and quiet operation rather than maximum cooling power. It delivers 27,000 BTU/h, which is 8,000 BTU less than the original. The zone split is 9K+12K, making it suitable for smaller spaces. The indoor unit has a different form factor, measuring 32.3 inches in width and 12.1 inches in height. It features soft airflow technology to reduce draftiness. This model retains smart app control and dual-zone independence. Choose this if you prioritize silent, draft-free comfort in smaller zones over raw cooling capacity. It is a practical option for residential areas where noise and air movement are concerns. It offers a more comfortable airflow experience but with significantly less total cooling power than the original 35K unit.
Della 27K BTU 2-Zone Concealed Ducted
The Della 27K BTU 2-Zone Concealed Ducted unit is designed for hidden installations within ductwork. It provides 27,000 BTU/h cooling, which is 8,000 BTU less than the original. The indoor unit measures 27.5 inches in width and 7.87 inches in height, fitting into standard duct spaces. It includes a condensate pump for flexible drainage options. This model maintains smart app control and dual-zone management. Select this alternative if you want a concealed aesthetic similar to the original's intent but with a ducted configuration. It sacrifices the visible 360-degree airflow of the ceiling cassette for a hidden installation. It is ideal for medium spaces where aesthetics and efficiency matter more than maximum cooling capacity, offering a cleaner look at the cost of some raw power.
