Light-commercial rooftop units
Trane's eFlex light-commercial rooftop units include 6 to 10 ton sizes, providing high-efficiency light-commercial packaged rooftop units that range from 3 to 17.5 tons.
Trane eFlex technology combines indoor and outdoor fans with variable speed compressors to increase efficiency and performance to create a low cost of ownership for the lifetime of the products. Trane eFlex variable-speed compressors and fans match their output to the cooling demands of the space by operating at their fastest levels when demand is high, and modulating to slower levels when demand is low. This operational flexibility allows Trane rooftop units to achieve an ultra-high Seasonal Energy Efficiency Ratio (SEER) up to 20.1, and an Integrated Energy Efficiency Ratio (IEER) exceeding 23 on some models, while maintaining Energy Efficiency Ratios (EER) as high as 13.
