Lennox Raider rooftop line adds 7.5- to 12.5-ton models
April 8, 2014 - Lennox has expanded its light commercial Raider rooftop unit line to include 7.5- to 12.5-ton models, adding to its existing offering of 3- to 5-ton units. Designed to be compatible with most replacement installations, Lennox says Raider units are built to fit the most popular 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. An optional MSAV supply fan claims to optimize energy efficiency by matching fan speed with compressor demand, while a field- or factory-installed BACnet option boasts seamless integration with building automation systems.
