Sales & Installation Of Standby & Other Models
A generator dealer serving Salt Lake City and other northern and central Utah locations, T-Rex carries a comprehensive lineup of portable units for everything from recreation and the outdoors, to backup power for residences and small businesses, to construction and contracting work. In addition, T-Rex Generators supplies permanent standby units to Salt Lake City homes and commercial entities. 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 that will fit your needs. In addition to portable and standby units, T-Rex also carries tractor-driven or PTO generators, 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. Salt Lake City's elevation averages 4327 feet above sea level. July, the city's warmest month, can easily reach or surpass 95 degrees Fahrenheit. In fact, statistics show that Salt Lake averages 23 days of 95 degree or higher heat each year. Why are these numbers important? We'll endeavor to explain....
Altitude and temperatures have an impact on local generator operation because manufacturer ratings of running and surge watts are always made at sea level, and in moderate to warm temperatures (no higher than 85 degrees). Any deviation from these idyllic generator conditions will begin to erode 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 tangible 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 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 here in Salt Lake City) multiplied by the projected power loss (3.5%) divided by 1000 feet (4327 x (3.5/1000) = 15.14%). Here in Salt Lake, a 7500-watt generator will produce slightly less than 6400 watts, a significant power loss if you're counting on full generator output.
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 or simply not running the load. Any time your intended load is considered critical (you can't afford to have it fail), if it consumes all of a generator's rated (sea level) capacity then you will have no choice but to seek a larger model.
