The Avtron Model K711H Load Banks are intended for use
as a supplemental load for lightly loaded engine gen sets.
The Avtron K711H “Roof Top” Style Load Banks are designed for mounting on sound attenuated
enclosures and are available in a variety of frame dimensions. The load banks are permanently
mounted and sized to match the exhaust opening. The K711H load banks utilize the engine
cooling air rather than an internal cooling fan found on conventional load banks.
The primary cause of premature diesel engine failure is “wet-stack ing” which is literally “wet”
unburned fuel accumulating in the engine exhaust (“stack”), due to under-loading of the generator.
Diesel engines that are lightly loaded or allowed to idle for long periods never reach their recom-
mended full operating temperature. Over time, this unburned fuel coats the combustion chamber
and pistons with a thick coating of tar and carbon build-up, reducing efficiency and life span of the
engine considerably. A supplemental radiator load bank helps to “burn-off” these harmful carbon
deposits, greatly increasing engine life.
These units are offered in 208, 240, 480, or 600 volt versions (at 60 Hz) or 380, 400, or 416 volt
versions (at 50 Hz). Load rating varies and typically ranges between 5 and 500 KW. Most engine
manufacturers recommend sizing the radiator load bank to 40-60% of engine nameplate rating
to eliminate “wet-stacking” problems.
The load bank is controlled from individual load-step toggle switches. The control panel is provided
as a remote wall mount style which is required for “roof top” applications.
The K711H “roof top” style load bank is intended for use as a supplemental load for lightly
loaded engine generator sets. The load bank utilizes the engine cooling air to cool the resistive
load elements.
