Description
Ener-G-Rotors, Inc sells devices that represent a breakthrough in the economic generation of electricity from low temperature heat. Low temperature heat sources can be found in industrial processes, commercial buildings, solar thermal collectors, geothermal sources, biomass boilers, and combustion engines. We have an exclusive license for a patented technology, called a Trochoidal Gear Engine (TGE™), which is more efficient, cost effective, and durable than existing technologies. We have working 5kW systems that demonstrate the efficiencies we can achieve, and will soon commercially launch the GEN4, our 40-60kW system, targeted at the industrial waste heat market. The worldwide market to economically turn this low temperature heat into electricity and achieve greater energy efficiency is estimated at more than $50 billion.
Our Products
The GEN4 is a “drop-in” appliance that takes 150°-400°F hot water or steam as an input to produce 40-60kW of electricity. The GEN4 helps our customers lower energy costs and reduce their carbon footprint by converting energy they have already paid for into electricity. Rather than throw away low grade heat, our customers can now extract additional monetary, environmental, and public relations value from that energy.
The GEN4 is:
Efficient – The heart of the GEN4 is the Trochoidal Gear Engine, an expander with very little friction, which translates into increased efficiency. That increase in efficiency means our technology creates a low temperature heat market where there is little competition.
Economical - The GEN4 is cost effective to manufacture and maintain. In most cases, there is less than a two or three year payback to customers paying as little as 6¢/kWh.
Durable - The TGE is designed with no sliding contacts and few moving parts, resulting in a long lived, reliable, low maintenance expander.
Non-disruptive - With only four hoses and a wire to connect, the Ener-G-rotors system does not affect the manufacturing process and is easy to install. With a 35 sq. ft. base, the Ener-G-Rotors appliance can be located close to the low energy waste heat stream.
Our Technology
The enabling technology behind our products is the patented Trochoidal Gear Engine™ (TGE™) which is used as an expander in an organic Rankine cycle (ORC). The low friction and simple design of the TGE makes it the most efficient, durable, and cost effective expander for ORCs at low temperatures (150°F to 400°F) and small sizes (<200kW).
The TGE™ itself is a positive displacement device, a modified gerotor that significantly lowers frictional losses. This reduction in friction has two benefits: (1) higher efficiency in turning heat into work, and (2) less gear wear which lowers maintenance costs. This improvement in efficiency does not come at the cost of added complexity however. The design of the TGE™ is still very simple with only two moving parts. The efficiency of the engine allows us to keep our costs low and create cost-effective systems as small at half a kilowatt to as large as 500kW eventually.
