Rooftop units: Lennox
Lennox has expanded its Energence® rooftop line with new ultra-high-efficiency models. Lennox’ ultra-high-efficiency Energence units feature efficiencies of up to 21.5 IEER and 13.9EER resulting in overall lower operating costs and service, which the company says contributes to the lowest total cost of ownership. Energence ultra-high-efficiency units are designed to offer customers energy savings with 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%, 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 units are backwards compatible with many existing Lennox rooftops, offering a solution for replacement applications. Outdoor sound levels are as low as 81 dBA.
