Innovation never felt so good.™
Commercial-grade backup power offers dependable protection during unexpected power outages |
Your family probably doesn’t think much about whether the refrigerator is running so your food won’t spoil, or whether the furnace is keeping the house warm on a cold winter day, or if the lights will come on when you flip the switch—until a power outage occurs and everything quits. |
|---|---|
Available in 12kW, 18kW and 30kW sizes powered by natural gas or propane |
Backup Power Gives Your Family |
Clean, reliable, digital voltage regulation protects sensitive electronic equipment from damage caused by unstable power quality or high levels of total harmonic distortion |
Whether the result of severe weather or of an increasingly unstable, overburdened electrical grid, power outages are inconvenient at best. But they can also be costly and potentially dangerous—even fatal, if you rely on medical equipment. Lennox™ Residential Generators provide the ideal solution: safe, reliable, automatic backup power for your home that lets you live your life without interruption. |
Delivers more power for better performance with the lowest operating noise of all competitive units tested |
Power that matches your family’s lifestyleLennox residential generators are available in a range of sizes (12kW, 18kW and 30kW) to meet the needs of every home. Less backup power is required to meet basic electrical needs, such as a refrigerator, dishwasher, air conditioner or furnace, lighting, TV, computer and garage door opener. Additional power is needed for items like an electric range, multiple air conditioners, electric clothes dryer, security system, sump pump and large wine cellar. For help in determining which generator model provides sufficient kilowattage for your home, see the Generator Sizing Tool at www.lennox.com. |
Reliable power when you need it most
Safer power for sensitive electronics |
|---|
Unlike competitive products that can damage and degrade sensitive home electronics with unstable power quality or high levels of total harmonic distortion (THD), Lennox™ generators deliver cleaner, more stable power that meets strict utility requirements and electrical standards for THD. |
Reliable performance |
Lennox’ commercial-grade digital controller provides increased peak motorstarting capability and the highest-tested surge capacity for large start-up loads such as air conditioning. Voltage regulation varies only +/- 1.5%, even under a full-house load. Quality extends to the outside, too, where the saltspray- tested paint used on exterior surfaces provides lasting durability and rust prevention. |
Quieter operation |
Sleek, weather-resistant sound enclosures keep operating noise levels the lowest among all competitive units tested—10 times quieter than the leading competitor.* You and your neighbors won’t be bothered when the unit performs self-diagnostic test runs, or when it’s running at full operation speed. |
Quicker response time |
When an outage occurs, Lennox generators restore power in as little as 10 seconds—three times faster than competitive models. |
Automatic diagnostic testing |
Lennox generators perform a 20-minute, full-speed, self-diagnostic test each week to ensure peak running condition. |
Simple installation and maintenance |
Fast, flexible installation is accomplished through a simple wiring connection with the automatic transfer switch and an integrated polymer pad on the air-cooled RGEN12 and RGEN18. No break-in time is needed once the unit is installed—all Lennox generators are tested and ready to use prior to shipping. |
