USA: Carrier’s new WeatherMaker line of rooftop units now feature the company’s EcoBlue beltless direct-drive vane axial fan system.
Previously available only on select units, the EcoBlue system is said to be up to 40% more energy efficient than conventional forward curve belt-driven fan systems. With 75% fewer moving parts – there are no fan belts, pulleys, shafts or shaft bearings – and a specially designed high-density fan blade, the advanced design can significantly reduce operating, installation and maintenance costs.
The addition of EcoBlue Technology also contributes to meeting the 2023 US Department of Energy minimum efficiency requirements for HVAC equipment.
The new WeatherMaker units with EcoBlue technology are lighter than past models while keeping the same footprint and cabinet size. The new units with 7.5 to 12.5 ton models will have Integrated Energy Efficiency Ratios (IEERs) up to 15.2. Along with perfect fit capabilities to eliminate the need for expensive adapter curbs or total roof curb replacements, the units will have optional MERV-13 four-inch filters, air management economisers for fresh air and free cooling, and SystemVu controls that provide smart diagnostics and real-time information to monitor and help optimise system performance.
