Rooftop unit: Lennox
Lennox has expanded its light commercial Raider® rooftop unit line to include new 7.5- to 12.5-ton models, adding to its existing offering of 3- to 5-ton units. Designed for compatibility with many replacement installations, Raider units are built to fit the most curb sizes virtually eliminating the need for an adaptor curb on many replacement jobs. Available in gas/electric and electric/electric models, 3- to 12.5-ton units offer efficiency levels of up to 13 SEER, 11.5 EER, and 13.2 IEER.
The Raider unit also offers many design features which the company says were created to simplify the installation process. With an optional MSAV® supply fan that optimizes energy efficiency by matching fan speed with compressor demand, users can see a further increase in utility savings. A field- or factory-installed BACnet® option offers seamless integration with building automation systems.
