DALLAS – (July 15, 2014) – Lennox has expanded its popular Energence® rooftop line with new ultra-high-efficiency models that are the most efficient, lightest and quietest rooftop units in its class.*

“One of the attributes that our customers have come to expect from Lennox is cutting-edge innovation, and with our new Energence ultra-high-efficiency units we’ve achieved a new pinnacle in innovation,” said Cindy Sparrow, Vice President of Product Management and Marketing. “Our customer feedback plays a significant role in the development of our products and these new units were designed to meet not only our customer’s most requested benefits, but industry leading results in the areas of energy efficiency, sound and weight, for comparable competitive units.”

Lennox’ ultra-high-efficiency Energence units feature industry leading efficiencies of up to 21.5 IEER and 13.9EER resulting in overall lower operating costs and service which contributes to the lowest total cost of ownership. Energence ultra-high-efficiency units are designed to offer customers ultimate energy savings with innovative features such as the Advanced Cooling System and the DirectPlus™ blower system. In addition to sustained savings, the Energence ultra-high-efficiency lineup exceeds ASHRAE 90.1 minimum standards by 92 percent, exceeds CEE Tier 1 and 2 efficiency minimum requirements, and qualifies for many potential utility rebates and incentives, while also providing additional options to meet California Energy Code Title 24.

Energence ultra-high-efficiency models come standard with MSAV® (multi-stage air volume) supply fan technology with the option of either the belt-less DirectPlus™ blower system or the belt-drive blower system. The DirectPlus blower system is a patent-pending design that combines the motor and electronics into one unit which uses fewer components and features slide-out access to help reduce maintenance time and costs.

Built to suit a variety of applications, Energence ultra-high-efficiency units are backwards compatible with many existing Lennox rooftops, offering a simple solution for replacement applications. Up to 42% lighter than the competition,* these units make it the perfect choice where rooftop structural integrity may be a concern. Plus, with the lowest outdoor sound level as low as 81 dBA, up to 11 dBA quieter than competing units,* Energence ultra-high efficiency units can potentially help eliminate costs associated with reducing sound within a building.

One signature feature that makes Energence rooftop units a top choice among businesses is the Prodigy® 2.0 unit controller. With more than 250 adjustable parameters that meet almost any design specification, controlling the Energence rooftop is easier than ever.  Enhanced display and simplified navigation allows for easier installation, operation, troubleshooting, unit monitoring, and servicing.
