Cooper&Hunter Hyper Heat 3-Zone Ducted Mini Split AC & Heat Pump -- 55000 BTU (4.6 Ton) Without Shut-off Valves, Slim Ducts Units (6K+18K+24K) BTU, Inverter Technology, 230V, Heating & Cooling
Bring flexible, concealed comfort to your space with the Cooper & Hunter Slim-Duct system. A 55000 BTU outdoor condenser (No Shut-off Valves) powers slim-profile duct air handlers that disappear into ceilings, soffits, or chases for a clean, unobtrusive finish. This inverter heat pump provides independent control in 3 zone(s) and supports low-ambient heating performance down to -22 F.
Slim-Duct air handlers use TU1 copper tubing, medium / high static pressure blower performance, built-in Smart Kit connectivity, and R454B refrigerant (low-GWP) for efficient operation up to 22.2 SEER2. Equipped models include a refrigerant sensor to help maintain optimal operation.
Key features
Concealed comfort + ducted flexibility
- Slim-profile duct unit hides in ceilings/soffits for a clean finish
- Ideal for short duct runs to discreet registers/grilles
- Designed for Single-Zone or Multi-Zone applications (model dependent)
Performance
- 3-zone independent temperature control
- Medium static pressure models for standard duct layouts
- High static pressure models for longer runs / higher resistance (size dependent)
- High-efficiency operation up to 22.2 SEER2
- Quiet operation (Outdoor unit as low as 65 dB(A), No Shut-off Valves; Indoor as low as 32.5 dB(A))
- Reliable heating down to -22 F ambient
Built-in components
- TU1 copper tubing for durability and heat transfer efficiency
- Built-in Smart Kit with downloadable C&H app (where equipped)
- Refrigerant sensor (where equipped) for system monitoring
- Turbo mode for rapid conditioning
- 2025 model platform using R454B refrigerant (low-GWP)
Flexible installation
- Choose between horizontal and vertical installation (model dependent)
- Designed for tight spaces such as ceilings, soffits, or wall chases
Static pressure and install orientation vary by size (example: 24K can support high static pressure and flexible orientation). Confirm your model’s ESP range and dimensions in the indoor spec table below.
