The Avtron Model K711 Load Bank are intended for use as a supplemental load for lightly loaded engine gen sets.
The Avtron K711/K711A/K711L load banks are designed for duct or radiator mounting and are available in a variety of frame dimensions. The load banks are permanently mounted to the front of the engine generator and sized to match the radiator or exhaust duct opening. The K711 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-stacking” 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 recommended 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 ranges between 5 and 1250 KW. Most engine manufacturers recommend sizing the radiator load bank to 40-60% of engine nameplate rating to eliminate “wet-stacking” problems.
The K711 load bank is controlled from a built-in control panel which contains the individual load-step toggle switches. The control panel is also available sized for standard 19" [482.6] rack mounting when remote installation of the panel is desired.
The K711 family 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.
