ECO-HEAT maximizes diesel engine performance
Raises the engine load and heats the exhaust directly to save space and energy.
Watlow’s ECO-HEAT exhaust gas heating system eliminates problems under low generator load conditions, including increased engine back pressure due to excessive soot loading, poor NOx conversion and fouled EGR valves.
The system works as an internal load bank in medium stationary and mobile diesel generator applications. It installs in the exhaust pipe and provides heat directly where it’s needed within the after-treatment system.
Using electricity from the generator, it raises the engine load and heats the exhaust directly to save space and energy.
If generator load demand increases, the system gradually reduces its load and thermal output, and shuts off as soon as exhaust gas temperatures reach acceptable levels.
Watlow is a manufacturer of industrial heaters and temperature sensors based in St. Louis.
