Energence® rooftop unit with MSAV® supply fan honored by leading industry magazine

Dallas, TX – (July 1, 2012) – Lennox Industries’ energy-efficient Energence® light commercial rooftop unit with the innovative new MSAV® (multi-stage air volume) supply fan technology has been recognized by BUILDINGS Magazine as one of its top Money-Saving Products for 2012.

“We are honored to receive this recognition,” said Mike Walker, Director of Marketing and Product Management, Lennox North America Commercial HVAC. “Our MSAV supply fan technology, when applied to the high efficiency Energence rooftop unit helps boost efficiency ratings by up to 27%. This allows our customers to further reduce their energy usage while still meeting comfort requirements.”

By using a variable frequency drive and Lennox’ patent-pending control algorithms, this option allows the unit to lower airflow for a dramatic reduction of energy use in multiple modes of operation—including part-load cooling, heating, ventilation and free-cooling operation—resulting in year-round utility savings.

Lennox’ MSAV supply fan technology also allows quick and easy startup of the unit, while offering users the flexibility to customize airflow settings by making simple changes in the unit’s control system.

MSAV Supply Fan Technology benefits include:

  • Part-load (IEER) energy savings, with efficiency improvements up to 27%
  • Energy reduction during heating, ventilation and free-cooling operation
  • Quick and easy start up plus the flexibility to customize up to seven different airflow settings by using the Energence unit’s Prodigy unit controller
  • May help customers qualify for utility rebates due to high IEER levels and/or having equipment installed with a variable-frequency drive
  • Meets the ASHRAE 90.1-2010 and California Title 24 requirements for single-zone VAV systems

MSAV supply fan technology is available on Lennox’ Energence (7.5- to 25-ton models) plus the Strategos® (10- to 20-ton models) and Landmark (7.5- to 25-ton models) rooftop units.
