Improve Control Over Energy Bills, Sustainability Goals with Newly Upgraded L Series® R410A Rooftop Unit

DALLAS, TX – July 3, 2007 – Lennox Industries Inc. has increased the energy-efficiency in several capacities of the L Series® R410A rooftop unit product line, making the popular units an even smarter choice for businesses that want a reduced total cost of ownership while improving their environmental commitment.

Designed with environmentally friendly R410A refrigerant, the newly enhanced units offer efficiencies up to 11.3 EER and 12.3 IPLV, an increase in efficiency rating as high as 7.7% EER and 8.0% IPLV, depending on the unit. These upgraded systems are available in 7.5-ton, 8.5-ton and 10-ton capacities to meet a wide range of applications.

Lennox engineers improved the L Series R410A units’ efficiency by incorporating more efficient compressors and a new coil design developed to help reduce energy usage. The L Series units will be available for delivery to job sites beginning early September 2007.

In addition to the new higher efficiencies, L Series rooftop units offer:

  • Centralized control and fast, simple troubleshooting via the Integrated Modular Controller
  • The optional Humiditrol® dehumidification system for controlling moisture levels to improve comfort and indoor air quality
  • Multiple compressors for efficient cooling with up to four-cooling-stages capability
  • Thermostatic Expansion Valves for peak cooling performance across the entire application range
  • A full perimeter base rail and independent motor mount for faster, easier installation and maintenance
  • Optional integration with the L Connection® Network, Lennox’ HVAC and building control system that can tie together a variety of third-party products for increased performance
