Generators Dealer Serving Salt Lake County
Sales & Installation Of Standby & Other Units
A generator dealer serving Salt Lake County and other northern Utah locations, T-Rex carries a comprehensive 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 Salt Lake County homes and commercial 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 local use should be conscious of altitude and summer temperatures when models for a given application are being considered. The elevation of Salt Lake City itself is 4327 feet above sea level on average. Other cities and towns in the county are similar. The altitude of our county's mountainous areas, meanwhile, can exceed 10000 feet. In July, the hottest month of the year statewide, temperatures here can easily hit (or beat) 95 degrees Fahrenheit. Why are these numbers important? Continue reading....
Your local geographic information should be considered when purchasing a generator for any application significantly above sea level. 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 idyllic 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. If outside temperatures reach 100 degrees or more, load performance can begin to suffer, especially if a generator is also being operated at high altitude. For high-altitude generator operation, the rule of thumb is a 3.5% loss of output (includes both running and surge watts) for every 1000 feet gained in elevation (above sea level). Power loss at any elevation can be calculated like this: altitude of location (4327 feet in Salt Lake City for example) multiplied by the projected power loss (3.5%) divided by 1000 feet (4327 x (3.5/1000) = 15.14%). Try applying these results to a 3000-watt camping generator (3000 x .1514 = 454.20). In Salt Lake City then, you could expect this 3000-watt camping unit to lose 454.20 watts (leaving its maximum capacity at around 2550 watts - a steep enough decline to affect some applications).
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.
