Generator sets are a necessity of any onsite power  system. Compliant Power Systems manufactures a full line of Natural Gas  Generator sets from 50KW to 500KW. CPS Gen-Sets are powered with custom built  5.7 and 9.8 liter lean-burn engines along with Cummins natural gas  engines.  They are equipped with Marelli industrial/marine series  alternators and are the result of integrated design and manufacturing intended  to meet your requirements for reliability, power quality, rated performance, and  efficient operation. Lean–burn gas generator sets are designed to provide  reliable performance, high fuel efficiency and very low emissions.  This  makes them ideal for applications such as high–hour peaking and prime power.  Running on a lean mixture of fuel and air, this design significantly reduces the  production of nitrogen oxides (NOx) and increases fuel efficiency. The result is  a generator set with a high power output, maximum thermal efficiency and NOx  emissions as low as 0.5 grams per brake horsepower–hour. All CPS Generators are  equipped with telemetry that allows us to monitor performance and which alerts  us the moment a problem occurs. Compliant Power Systems unique lean–burn design  combines high power densities and included maintenance intervals for an  economical solution to prime power needs.
