Exhaust to Electricity

Suitable for a wide variety of exhaust sources, optimized for hot gas at temperatures ranging from 350 to 600 °C. The PowerModule-γ™ delivers up to 850 W of DC power (see specifications below).

Reliable, Robust Power

Rigorously field-tested to ensure reliable operation through many cycles over extended periods of time at high temperatures. Minimal pressure drop to ensure your process is not disturbed.

Simplicity, Modularity

The PowerModule-γ™ comes fully assembled and inserts directly into your exhaust flue with a suitable transition duct or pipe. Alphabet Energy can provide information to help you configure your system and utilize the PowerModule-γ™ effectively, including inverting your DC power to AC.

High-Power, Liquid-Cooled, Low-Pressure Drop Design

The PowerModule-γ™ can also be modified for use in primary power applications where source temperatures are higher than 600 °C, such as in flame-fired products. Please inquire to learn more.

 

Specifications

The PowerModule-γ™ is currently in beta testing. Performance is subject to change. Future versions may have different dimensions and power output. Please place an order and deliver feedback on your requirements so we can determine the right solution for you.
