Lennox Energence Rooftop Unit

Lennox Energence Rooftop Unit: The Efficient Solution for Commercial Buildings

Lennox Energence Rooftop Units are an industry-leading solution for commercial building owners who want to save energy and minimize operating costs. With an efficiency rating of up to 18.0 SEER, 15.5 IEER, and 12.8 EER, these rooftop units are designed to reduce energy consumption while providing optimal performance. The SmartAirflow™ system, available as an option, can save up to 35% of annual ventilation energy consumption compared to traditional rooftop units. The MSAV® supply fan provides year-round savings and comfort with reduced energy consumption, improved indoor air quality, and code compliance. With the SunSource® Commercial Energy System, you can achieve effective efficiency levels of 34 SEER, 43 IEER, and beyond. These energy-efficient features make Lennox Energence Rooftop Units an excellent investment for any commercial building owner who wants to reduce energy expenses and improve the bottom line.

Comfort and Indoor Air Quality

Lennox Energence Rooftop Units are designed to provide exceptional comfort and indoor air quality (IAQ) to building occupants. The units feature a corrosion-resistant, removable, reversible, double-sloped drain pan that provides application flexibility, durability, and improved serviceability. Foil-faced insulation on all internal surfaces that contact airflow helps minimize airborne fibers and improve IAQ. Multiple cooling stages help reduce temperature swings and maintain tighter control for improved comfort. The ComfortSense® 8500 Commercial Thermostat enables all four stages of heating and cooling, while the patented Humiditrol® dehumidification system allows for independent control of temperature and humidity, providing enhanced comfort control.

Reliability and Serviceability

Lennox Energence Rooftop Units are designed for reliable, long-term operation and easy serviceability. The Environ™ coil system significantly reduces refrigerant charge requirements and offers innovative technology that helps maximize reliability and sustainability. The Prodigy® 2.0 unit controller with enhanced user interface makes setup, troubleshooting, and servicing easier than ever. Each unit tracks the runtime of every major component and records the date and time when service or maintenance is performed. The SmartWire™ system simplifies field sensor or thermostat installation through advanced connectors that are keyed and color-coded to help prevent miswiring. The units also feature hinged access panels for quick access to components and protection for panels and the roof during servicing, an isolated compressor compartment that allows performance check during normal compressor operation without disrupting airflow, and a slide-out blower that allows quick belt tensioning, adjustment, or replacement and makes cleaning the blower easier.
