Description

The Daikin Oterra RXF18AXVJU outdoor condenser, paired with the FTKF18AXVJU wall‑mount indoor unit, delivers 18,100 BTU of cooling and 21,600 BTU of heating capacity. Featuring R‑32 refrigerant and inverter-driven variable-speed hermetic swing compressor, this unit achieves up to 21 SEER2, 12 EER2, and 9.6 HSPF2—confirmed by AHRI‑rated data. Designed specifically for wall-mount applications, it provides a compact yet efficient solution suitable for residential and commercial spaces.

Performance
Leveraging smart inverter technology and a robust fin-and-tube outdoor coil, this system consistently delivers up to 30% greater efficiency compared to fixed-speed models . With a cooling power draw of 1.508 kW and heating input of 1.756 kW, its COP and EER2 reflect optimized performance: 3.60 COP in heating and 12 EER2 in cooling . It supports line sets up to 98.5 ft and vertical separations up to 65.6 ft, making it flexible for a range of installation layouts.

Smart Features
The Oterra system integrates with Daikin’s DKN Cloud App for real-time remote control and status monitoring—a strong fit for smart home setups, rental units, and commercial zones. It also includes a backlit wireless remote, programmable dry mode, auto-changeover, self-diagnostics, and auto-restart after power failure. The system supports discrete zoning, allowing property managers and contractors to tailor comfort for individual zones.

Comfort & Noise
Indoor sound levels range from a low 33 dBA (quiet mode) up to 49 dBA at high fan speed; the outdoor RXF18AXVJU operates at 54 dBA. Indoor airflow peaks at 754 CFM in turbo mode, with operations down to 395 CFM on quiet mode , ensuring balanced comfort and even temperature distribution. Blue Fin hydrophilic coil coating and a 16-hole drain pan accelerates condensate drainage and helps minimize noise and humidity buildup.

Use Case Fit
At 18 k BTU, this unit is ideal for mid-sized spaces like family rooms, offices, and multi-family apartments (~600–900 ft²). It maintains efficient cooling from 50–122 °F DB and sustains heating performance down to 5 °F WB, with extended operation to –4 °F using wind baffle settings. It accommodates diverse regional needs—from Florida’s humidity to colder continental climates—while permitting rooftop or side-wall condenser placement thanks to its extended piping capability.

Value & Reliability
Constructed by Daikin—an HVAC industry leader—the Oterra RXF18AXVJU features anti-corrosion treatment on the outdoor heat exchanger and durable hydrophilic Blue Fin protection. The outdoor drain pan with 16 holes enhances moisture management and reduces ice build-up . Simplified service access (removable drain pan, blower wheel, fan motor) and self-diagnostics streamline maintenance and lower service calls, offering dependable value for contractors and property managers.

Summary Wrap‑Up
Overall, the Daikin Oterra RXF18AXVJU–FTKF18AXVJU delivers market-leading efficiency, intelligent control, and consistent comfort in a compact package tailored for both D2C buyers and wholesale partners. With 21 SEER2/9.6 HSPF2 ratings, variable-speed precision, quiet operation, and smart connectivity, it supports flexible installations, scalable zoning, and long-term reliability. This heat pump exemplifies quality, performance, and value, making it a compelling offering for homeowners, commercial specifiers, and rental property operators seeking proven HVAC solutions.
