S-Class™ 35- to 50-ton Rooftop Units from Lennox Receive AHR Expo Innovation Award Honorable Mention

DALLAS, TX – February 1, 2006 – S-Class™ 35- to 50-ton rooftop units from Lennox received honorable mention in the cooling category for the AHR Expo Innovation Awards this year.

The AHR Expo Innovation Awards Competition, which is held in conjunction with the International Air-Conditioning, Heating, Refrigeration Exposition (AHR Expo) every year, is designed to promote and encourage product innovation by recognizing exceptional achievements. A panel of judges, made up of ASHRAE members selected for their expertise and knowledge of the industry and its products, reviewed and evaluated all submissions. Product entries were judged for innovation, application, value to user and market impact.

The S-Class rooftop product line provides a complete heating, ventilation, air conditioning and indoor environmental quality solution for commercial buildings featuring single zone, bypass zoning and zoning applications. With up to 10.8 EER and 13.2 IPLV, the S-Class product line is the most energy efficient rooftop unit in the industry.1 It is also one of the first to offer environmentally friendlier R-410A refrigerant.2

The S-Class rooftop product line has pushed past the previous boundaries of high energy efficiency and low lifecycle cost. This will help spur other manufacturers to develop more energy efficient large rooftop units.
