Energy Efficiency Improved in 13- to 20-ton L Series® R-410A Rooftop Units

DALLAS, TX – September 6, 2007 – Now there are more ways than ever for businesses to reduce their operational expenses and lower their total cost of HVAC ownership. Lennox Industries Inc. has improved the energy efficiency of its L Series® R-410A rooftop unit product line in units as large as 20 tons.

Higher-efficiency compressors and a more efficient coil design have been integrated into L Series R-410A rooftop units in 13-, 15-, 17.5- and 20-ton capacities. With these improvements, the units allow efficiencies as high as 12.0 EER and13.3 IPLV. This is the second enhancement to the popular L Series line this year: 7.5- to 10-ton models were upgraded earlier this summer.

Designed to help businesses control costs while meeting sustainability goals, the new 13- to 20-ton units are expected to be available for delivery by late October 2007, while upgraded 7.5- to 10-ton units are being shipped to job sites now. The upgraded units each feature environmentally friendlier R-410A refrigerant, helping businesses avoid higher costs that may be linked to the upcoming phase-out of chlorine-containing refrigerants such as R-22.

L Series rooftop units are designed for:

  • Faster, easier installation and maintenance, with features such as a full-perimeter base rail and toolless-access panels
  • Centralized control and simple troubleshooting via the Integrated Modular Controller
  • Advanced moisture control with the optional Humiditrol® dehumidification system
  • Peak cooling performance as a result of multiple compressors and the use of thermostatic expansion valves
  • Superior HVAC and building control via optional integration into the L Connection® Network, which ties together multiple units with other building functions such as lighting or exhaust fans
