Rotenso - TENJI
The Rotenso TENJI series is a complete line of ceiling cassette air conditioners built for fast, reliable HVAC installations. Designed for both residential and light commercial projects, this series delivers balanced airflow, quiet operation, and straightforward setup for technicians.
Flexible Installation Options
The TENJI cassette units support split, duosplit, and multisplit configurations. You can connect one indoor unit to a single outdoor unit, or link multiple indoor units to one outdoor compressor. The 4-way ceiling cassette design pushes air evenly across the room, making it ideal for offices, retail spaces, and open layouts. Standard ceiling grid mounting points allow quick suspension without custom framing.
Wide Capacity Range for Any Space
With cooling capacities from 2.1 kW up to 16 kW, the TENJI series covers almost every project size. Smaller units like the 2.1 kW and 2.6 kW models work well for bedrooms and small offices. The 3.5 kW, 5.0 kW, and 7.0 kW units handle medium rooms and shop floors. Larger spaces, conference halls, or open commercial zones are covered by the 9.0 kW, 10 kW, 12 kW, 14 kW, and 16 kW models. You can mix and match capacities in multisplit setups to match exact load requirements without oversizing.
Easy Maintenance and Service
Installers will appreciate the straightforward service design. The front panel lifts off quickly for filter access and coil cleaning. Refrigerant lines and drain connections are positioned for easy routing through standard ceiling voids. The units include built-in condensate pumps in most models, reducing the need for extra slope on drain lines. Clear wiring terminals and labeled control boards speed up electrical connections and troubleshooting on site.
Reliable Performance and Efficiency
The TENJI series uses inverter-driven compressors and high-efficiency heat exchangers to maintain stable temperatures while cutting energy use. Low sound levels keep noise complaints to a minimum, even in quiet environments. The units are built with corrosion-resistant coatings and durable housings to handle typical indoor conditions. With smart thermostat compatibility and programmable modes, the system adapts to daily usage patterns without complex programming.
