T-Class™ large split system with MSAV® supply fan technology offers year-round savings and comfort

Dallas, TX – (August 16, 2012) – Lennox’ MSAV® (multi-stage air volume) supply fan technology is now available on T-Class™ large split system units. Designed to offer year-round savings and comfort, the MSAV technology helps reduce energy consumption, providing up to 61% supply fan power savings and improves indoor comfort with up to 29% better moisture removal at reduced airflow operation. The MSAV technology achieves or exceeds the single-zone VAV supply fan requirements for ASHRAE 90.1 2010 and California Title 24. It is available as a field-installed, variable frequency drive-enabled option on 7.5- to 20-ton T-Class™ large split system units.

Lennox’ MSAV supply fan technology also allows quick and easy unit startup. Additional benefits of the T-Class large split system units with MSAV supply fan technology include:

  • Part load supply fan operational energy savings*
  • Quieter operation and improved system reliability with soft starts, reducing starting torque wear and tear on major components such as fan motors, belts and bearings
  • High/low energy-saving ventilation speed option, field selectable (100%/67%)
  • Two outdoor air minimum damper positions available to set optimal air intake, reducing energy costs associated with over ventilation.

In addition to the T-Class Large Split Systems, the MSAV supply fan technology is available on Lennox’ complete line of rooftop units, including: Energence®, Strategos® and Landmark® rooftop units.
