Lennox has added high-efficiency 7.5- to 10-ton, gas/electric and electric/electric models to its existing line of Landmark rooftop units. This factory-installed technology uses a variable frequency drive (VFD) to deliver supply fan power savings of up to 61% while still meeting comfort requirements. Additionally, high-efficiency Landmark models may help businesses qualify for state and local utility rebates. The Landmark unit’s flexible design offers more than 100 field customizable options and more than 30 features designed to reduce installation and service time. This includes an isolated compressor compartment for easier, more accurate charge confirmation; a slide-out blower that offers quick belt tensioning, adjustment, or replacement and easier cleaning of the blower wheel; and an accessible gas compartment that simplifies analysis and service.
