RoamAir R2 12V/48V DC Air Conditioner and Heat Pump

Overview The RoamAir R2 combines air conditioning and heat-pump heating in one compact rooftop system designed for campervans, trailers, and overland vehicles. Available in 12V and 48V configurations, the R2 connects to a compatible DC electrical system and provides heating and cooling through a single roof-mounted unit. At the center of the R2 is a twin rotary, double-rotor compressor. Compared with many conventional DC scroll compressor designs, this configuration provides smoother variable-speed operation, reduced vibration, lower noise, and improved efficiency in mobile and off-grid applications. The 12V model provides approximately 8,000 BTU of heating and cooling with an average power draw of 660 watts. The 48V model provides 10,000 BTU of heating and cooling with an average draw of 897 watts. A soft-start inverter design eliminates the large startup surge associated with many traditional air conditioners, reducing unnecessary stress on batteries and supporting electrical components. The R2 also provides 265 CFM of airflow and installs through a standard 14 x 14-inch roof opening. Important Info Select the voltage that matches your vehicle's electrical system. The 12V and 48V models are not interchangeable. The RoamAir R2 is not RV-C compatible. Before ordering, verify exterior roof clearance, the required 14 x 14-inch opening, and a finished ceiling thickness between 3.15 and 4.72 inches.

What is the difference between the 12V and 48V models? The 12V model provides approximately 8,000 BTU of heating and cooling and has a 660-watt average power draw. The 48V model provides 10,000 BTU of heating and cooling and has an average power draw of 897 watts. Select the model that matches your electrical system voltage. 2. Does the RoamAir R2 provide both heating and cooling? Yes. The R2 uses heat-pump technology to provide heating and air conditioning from the same rooftop unit. The 12V model is rated at approximately 8,000 BTU, while the 48V model is rated at 10,000 BTU for both heating and cooling. Heat-pump performance declines near freezing. Until cold-weather testing is confirmed, we recommend 37°F as a conservative minimum and a backup heater for colder conditions. 3. What makes the twin rotary compressor different? The twin rotary compressor uses two rotors to provide smoother operation and reduced vibration. It is designed to improve variable-speed performance, efficiency, and reliability compared with many conventional DC scroll compressor designs. 4. Does the air conditioner have a large startup surge? The manufacturer states that the soft-start inverter design has no startup surge current. This reduces the sudden electrical load commonly associated with traditional air-conditioner compressor startup. 5. What roof opening is required? The RoamAir R2 installs through a standard 14 x 14-inch roof opening. You must also verify sufficient exterior clearance for the complete 31.5 x 26.18-inch rooftop unit. 6. What ceiling thickness can it accommodate? The published adjustable ceiling-thickness range is 3.15 to 4.72 inches. 7. How much power does it consume? The 12V model averages 660 watts and has a published maximum draw of 792 watts. The 48V model averages 897 watts and has a published maximum draw of 994 watts. Actual consumption may vary with operating conditions, temperature settings, and compressor speed. 8. Will the R2 work with RV-C controls? No. The RoamAir R2 is not RV-C compatible. 9. What colors are available? A black interior faceplate with either a white or black exterior rooftop shroud. 10. What is the warranty? A one-year manufacturer's warranty per terms and exclusions.
