Gas Letdown Generator

We have developed an exceptionally efficient and unique power conversion engine, the Gas Letdown Generator (GLG). Energy recovery from natural gas letdown stations and city gates is now economically viable with this revolutionary pressure to power engine. We have redefined the economics of green energy.
This patent-pending device utilizes screw-expander technology, which has been utilized in the compressor business for over 100 years. By investing years of research, experimentation and true entrepreneurial and inventive genius, Mr. Langson has developed a method for this proven, low cost, low maintenance technology to operate as an energy conversion engine. The solutions to the challenges conventional turbines face are:

Capital Costs a The installed capital cost of the Gas Letdown Generator is less than $2,000 per kilowatt. We modify readily available and proven off the shelf components keeping the capital investment to implement a GLG to a fraction of what would be required for a turbine installation.

The screw technology that is the foundation of the GLG has a proven track record of literally, millions of hours of operation and tens of thousands of installations worldwide. It has proven itself to be reliable, durable and truly cost effective.

This is a total flow production machine, there are no heat exchangers, no organic medium to transfer energy thus the operating efficiencies in excess of 60% can and have been routinely achieved.
