Online Generators Warehouse Serving the State Of Utah
Sales & Installation Of Standby & Other Gensets
An online generator dealer serving the State of Utah, T-Rex carries a competitive lineup of portable units for everything from recreation and the outdoors, to the emergency backup of residences and small businesses, to construction and work-site support. T-Rex Generators also supplies permanent standby units to Utah residences and business enterprises. Whether you're in search of a portable model to run the rooftop AC in an RV, or a standby generator to provide backup electricity in the event of an outage or natural disaster, we have a machine to fit your needs. For tractor owners in search of standby power, T-Rex carries single and three-phase PTO or power-takeoff generators from 15 kW to 165 kW. PTO generators represent the most economical means of producing end-user electricity for anybody with a tractor or PTO-equipped vehicle.
Anyone who is purchasing a motorized generator for use in our state should be conscious of altitude and summer temperatures when sizing for a given application is being considered. All residents are aware that the average Utah elevation is well above sea level. Depending on your location, July temperatures in the state can range from about 92 degrees to over 100 degrees Fahrenheit. Why do issues like elevation and ambient temperatures matter? Check out the explanation below....
Your local geographic information should be considered when purchasing a generator for any application significantly above sea level (this is especially true if you are seeking an air-cooled small-engine driven unit). Manufacturer ratings of running and surge watts are always made at sea level, and in moderate to warm temperatures (no higher than 85 degrees Fahrenheit). Any deviation from these conditions will begin to erode a generator's output. For every five-degree temperature increase (over 85 degrees F), output tapers off by a consistent 1%. An increase of one or two degrees normally won't be problematic to an application. However, if outside temperatures reach 100 degrees or more, load performance can begin to suffer, especially if a generator is being operated at high altitude. For high-elevation generator use, the rule of thumb is a 3.5% loss of output (includes both running and surge watts) for every 1000 feet gained in elevation (starting at sea level). Power loss at any elevation can be calculated like this: altitude of location (for an example, we'll take Provo's 4551-foot elevation) multiplied by the projected power loss (3.5%) divided by 1000 feet (4551 x (3.5/1000) = 15.93%). Now apply the results of this calculation to a 6500-watt (7500 surge watts) portable generator (6500 x .1593 = 1035.45; 7500 x .1593 = 1194.75). In Provo, you could expect the generator described to lose about 1050 continuous and 1195 maximum watts. (leaving its output totals at around 5500 and 6300 watts respectively - a decline significant enough to affect any application that required the machine's full rated capacity).
Heat and elevation don't always require a more-powerful generator. If you know in advance, however, that the load you will be running requires full generator capacity (or if all available surge watts are needed to start an electric motor - such as the motor in an RV air conditioning unit), then you will have a choice between obtaining a larger machine than you would need at sea level for the same operation, or simply not running the load. Any time your intended load is considered critical (you can't afford to have it fail) - and if you know it will consume all of a generator's rated (sea level) running or surge capacity - then you will have no choice but to seek a larger model.
