PowerGen Series

Designed for rugged and remote operation, the PowerGen remote power generator provides reliable electrical power supply to the most demanding and mission-critical loads. Based on Qnergy’s no-maintenance and highly reliable PCK series Stirling engines, the generator package can work seamlessly with a variety of fuel supplies, including: natural gas, propane, ethane, biogas, and multiple associated gas streams. By means of its flexible and modular design, this generator package can be tailored to provide a broad range of power output architectures to meet the electrical requirements of each specific site load. This system provides line quality power at your site without waiting for the electric company or having right-of-way issues. The Qnergy PowerGen Stirling engine is perfect for Cathodic Protection; mainline valve sites; Telecom and SCADA. An available 5650 Watts means you still have power left over to allow for AC heat trace in colder climates with a controllable heat supply ratio of 2.5 - 3.5 times the amount of power produced. Unit supplies enough flexible electrical power and BTUs to allow for combined applications such as flow control, metering, monitoring, lighting, Instruments, actuators, analytics, SCADA, communications, heat tracing, tank heating.

Can this generator as a whole ignite external flammable gases? In other words, should you treat the PowerGen as open flame equipment, which impact its location on the site due to spacing requirements of this type of equipment? Answer: The Qnergy PowerGen 5650 has an enclosed combustion chamber that is fully encapsulated within heat exchangers in such a way that there is no exposed heated surface hot enough that could cause pre-ignition to external air-borne flammable natural gas. In terms of ingress of external air-borne gas via the exhaust system into the combustion chamber, we have a positive pressure combustion chamber which, when the unit is operating, prevents any ‘unintended’ flammable gas access to the combustion chamber.

About Sterling Engine Technology:

The original kinematic Stirling machine, developed over 200 years ago by Rev. Robert Stirling, did not attain significant technical or commercial success until the latter half of the 20th century. An increased focus on this technology over the last 50 years has led to significant recent breakthroughs in terms of operating concepts and supporting technologies. The principal “Stirling advantage” is that it is a closed-cycle external combustion engine, meaning the heat source is outside the engine and the inside of the engine can be sealed. Stirling engines also make use of a regenerative heat exchanger that allows them to re-use their heat. This regeneration feature is what makes the Stirling cycle efficient, in addition to allowing it at the same time to be powered by virtually any heat source (e.g., oil, gas, solar, wood, coal, nuclear, and other combustible natural waste). Qnergy employs an innovative variant to the well-known ‘classic’ Stirling engine, which is called the Free Piston Stirling Engine (FPSE). Qnergy has introduced additional proprietary designs which monopolize on the fundamental architectural reliability of the FPSE. By employing novel heat exchanger designs within the harmonically resonating thermo-mechanical structure, Qnergy generators transform heat into electricity directly by using linear alternators. Qnergy’s design breakthroughs have resulted in an extremely reliable, long-life, maintenance-free, and quiet, electricity generating platform. Qnergy’s FPSE generators, when heated at their absorber, can literally transform any flow of heat into a steady output of electricity. These same generators are packaged into Qnergy’s energy products, these make use of multiple types of fuels to generate grid-quality electric power.

About Qnergy, the manufacturer:

Qnergy (q-ner-gy) is a company focused on providing ultra-reliable solutions to energize the future global energy markets. Our technology is innovative, cost-effective, and efficient. With more than 40 years of expertise and proven reliability, Qnergy brings proprietary, high-performance Free-Piston Stirling engine technology to the marketplace for commercial, industrial, and residential applications. Their state of the art manufacturing facility, located in Ogden, Utah employs modern high volume automated procedures. The manufacturing lines are a key part of facilitating the precisely controlled processes that are at the core of each of Qnergy’s product offerings. The products OilPro provides have been thoroughly tested by Qnergy during the development stages. Qnergy engineering's Highly Accelerated Lifecyle (HALT) Testing regime of critical PowerGen components ensures we can deliver what we promise Qnergy's Sterling engines have benefited from the full weld development test lab so they can and have inspected coupon sample oxide layers and coupon sample grain structures during product development. Qnergy also have a vacuum furnace for brazing and helium leak detection capabilities for prototype parts. Lastly, Qnergy has a robust DFMEA process tailored for both FPSE’s and systems to identity and rank design risks.

Qnergy Facility

The Qnergy manufacturing facility is equipped for high volume manufacturing of engines and systems in over 60,000 square feet. This dedicated production line is a fully operational, semi-automated assembly line utilizing the latest production equipment. Following rigorous and stringent quality and safety standards, the team is able to produce, test and deliver our various products on time


Qnergy’s legacy is based on decades of experience providing high-reliability, no-maintenance, long-life missions including both terrestrial and deep space remote power generation platforms. Reliability is deeply ingrained within Qnergy’s culture. Qnergy chooses to provide high-performing products to its customers by designing products "with test". Design “with test” means designing products to stringent reliability targets and then “proving” this reliability by testing and intentionally failing parts within extreme, harsh operating parameters.  Tests to failure show us exactly where the margins are, establishes the validity of our products within their specified operating envelope, and helps speed up product improvement cycles. Here at the Qnergy Manufacturing site, as well as at our field test sites, Qnergy uses long-life product “success” testing to show that we know and expect reliability. With millions of total hardware operating hours Qnergy continues to demonstrate its capacity to design and manufacture product to the most stringent of reliability requirements.
