Doosan Portable Power now offers a generator option designed to reduce the potential for “wet-
stacking” (unburned fuel passing into the exhaust system) and the associated damage and
performance issues wet-stacking can cause for diesel generators.
An internally packaged Intelligent Load Management System (ILMS) option is designed to
improve machine performance and decreases potential downtime associated with Tier 4-
compliant mobile generators in light-load and fluctuating demand applications, says Doosan.
The ILMS option automatically adjusts the engine and exhaust temperature with supplemental
heat to ensure the generator operates at full capacity, regardless of load demands. According to
Doosan, this system avoids the forced downtime caused by load-bank testing, another method for
resolving wet-stacking issues, but requires the generator to be connected to an exterior device.
The ILMS system requires no operator control or monitoring, says Doosan, and the system is
compatible with any voltage output produced by the generator, meeting the needs of a variety of
applications, says the company, with no special setup or switching required.
This technology also reduces fuel costs compared with other methods of adding supplemental
load. It’s an ideal option for Doosan generators used in rental applications where load demands
are either unknown or incorrectly sized. For applications with fluctuating power demands, the
system can instantly respond to ensure full generator capacity is always available in the event of
a sudden heavy load demand, such as a motor start.
Doosan Portable Power offers the Intelligent Load Management System (ILMS) option across its
small to mid-size generator lineup and select large generator models, including the G25, G40,
G50, G70, G125, G150, G190, G240 and G325 models.
