Trane a brand of Ingersoll Rand, has expanded its portfolio of light-commercial rooftop units with eFlex technology to include 6 to 10 ton sizes, providing customers with a complete lineup of ultra-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.
“Many organizations are setting goals to reduce their building’s energy use, and they want a partner with the right technology and who understands how buildings operate to help them achieve this,” said Mark Bell, product manager, light commercial unitary, Trane. “By using the new Trane portfolio of rooftop units with eFlex technology, building owners can be assured they are getting the performance and efficiency required to reduce utility bills while also meeting or exceeding efficiency standards and keeping building occupants comfortable.”
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.
