Cleanergy Stirling

The Cleanergy Stirling engine is the most and longest independently tested engine of its kind. The engine origins from a Swedish engineering design, from which it has been developed refined and tested for over 20 years. The engine used today has been in operations since the late 1990s and have been independently tested in France, Spain, the United States and Russia. The tests have proven the engine in both world class efficiency as well as durability in long term testing. Further to the extensive testing of the Cleanergy Stirling solar unit, the Cleanergy gas engines have been successfully in operations in over one hundred locations for the past 20 years where over two million logged hours of operations have been accumulated. The gas powered CHP engine have successfully been subject to seismic stress test (simulating a 9.0 impact on the Richter scale) and tested in off-grid conditions interconnected with other CPU’s. The gas engine, being the same engine as the solar unit with gas heater, has further helped Cleanergy in securing the number one position when it comes to solar Stirling engine manufacturing.
