Trane expands portfolio of light-commercial rooftop units for commercial buildings

Davidson, North Carolina: Trane has announced that it has expanded its portfolio of light-commercial rooftop units with eFlex technology to include 6 to 10 tonne sizes, which it claims is a complete line-up of “ultra-high-efficiency” light-commercial packaged rooftop units that range from 3 to 17.5 tonnes.

The technology, the company said, 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. Furthermore, the company said that the 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, thereby achieving a 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.

“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.”
