FloAire's Rooftop Unit

  • Conserve Energy
  • Precise Control
  • Superior Efficiency
  • Industry Best Warranty

FloAire's RTU is designed from its core to conserve energy and save on operating costs. FloAire RTU's rare earth magnet inverter scroll compressor eliminates excessive cycling, premature unit aging, inefficient hard starts, and unnecessary energy consumption. RTU’s modulating technologies allow it to deliver the highest efficiencies at part-load conditions.

FloAire's RTU contains fully modulating refrigeration and optional hot gas reheat components that deliver the exact amount of air requested at the desired temperature and humidity. Variable speed components allow the unit to adjust its heating and cooling capacity to match the required load. This provides a consistent temperature throughout the space and avoids large temperature swings often associated with single stage equipment.

FloAire's RTU achieves an impressive 21.3 IEER rating (Integrated Energy Efficiency Ratio) which is over 1.5x the ASHRAE 90.1-2016 IEER standard. Designed with the future in mind, RTU is poised to exceed rising IEER standards for years to come.

FloAire's RTU comes standard with a 5 year parts warranty. An extended 10 year full unit warranty is included at no extra charge when units are maintained with a FloAire Preventative Maintenance subscription (terms and conditions apply). FloAire's RTU is designed with sustainability in mind and is built to last up to 25 years.
