The Rotenso HIRO series is a complete line of multisplit outdoor units built for modern air conditioning systems. Designed with installers in mind, these units cover a wide power range from 4.1 kW to 12.3 kW. Whether you are working on a small apartment or a larger commercial space, the HIRO series gives you the right capacity for every project. The series is split into two clear options: S-Line for premium performance and N-Line for standard efficiency, making it simple to match the unit to your client’s exact needs.

Easy Installation and System Compatibility

Installers will appreciate the straightforward design of the HIRO outdoor units. Each model features standard refrigerant connections, clear service ports, and a compact footprint that fits easily into tight mechanical rooms or exterior walls. The units are fully compatible with all major Rotenso indoor multisplit heads, allowing you to mix and match capacities without complex configuration. Wiring is simplified with standardized terminal blocks, and the built-in communication module ensures quick setup and reliable data exchange between indoor and outdoor units.

Reliable Performance Across All Capacities

The HIRO series delivers consistent cooling and heating output across its entire range. Models like the 5.3 kW, 7.9 kW, and 10.5 kW S-Line units are built with high-efficiency compressors and optimized heat exchangers, which reduce energy consumption while maintaining strong performance in extreme temperatures. The N-Line models, including the 4.1 kW, 5.1 kW, and 9.4 kW variants, offer dependable operation for standard residential applications. All units feature advanced defrost control and low-noise fans, ensuring quiet operation and minimal maintenance over the system’s lifespan.

Flexible Sizing for Every Project

Planning a multisplit installation is easier when you have a full range of outdoor units to choose from. The HIRO series covers capacities from 4.1 kW up to 12.3 kW, giving you the flexibility to connect multiple indoor units without oversizing or undersizing.
