LD Series Radiator Duct Mounted Load Banks 50 kW - 1000 kW
Load Banks Direct, LLC is a leading manufacturer of high-capacity Load Banks. The LD Series of Radiator Duct Mounted Load Banks offers simple, easy to mount, economical solution for providing diesel generators with a supplemental load to minimize the effects of wet-stacking during operation under lightly loaded conditions. LBD is setting the standard with intelligent operator controls, safety indication layouts, and adjustable load step resolution. The LD Series of duct mounted load banks provides a cost-effective solution for regularly scheduled maintenance testing of mission-critical standby emergency power generators.
- Cost-effective solution for routine generator testing
- Reduce engine wet-stacking | Improve engine emissions
- Branch circuit fusing virtually eliminates catastrophic failure
- Intelligent Safety Circuits, Indicators, and Operator Controls
Construction | Built to Last
LD Series of Duct mounted load banks are constructed of formed galvanized steel in an open-frame for direct mounting/coupling to the engine cooling system. The open frame houses the resistor load elements and contains an integral side-enclosure for customer load connections, load step contactors, controls, and fusing. The rigid enclosure provides an open-air cross-sectional opening of the load resistors designed to match the opening of the engine radiator or exhaust air duct.
LBD-PowerDyne™ Load Elements | When Quality Matters
PowerDyne™ Resistors are the most rugged in the industry. They are fully supported across their entire length within the air stream by stainless steel support rods which are insulated with heavy-duty, high-temperature ceramic insulators. Change in resistance is minimized by maintaining conservative resistor designs.
KW Load Capacity
The LD Series of Radiator/Duct mounted load banks is available in any size range from 50 KW through 1000 KW at any available single phase and three phase Voltage (up to 600 Volts AC). They are intended for use as a supplemental load to the generator set and are typically sized at 50% of the generator KW rating.
- Illuminated Main Power On/Off switch
- Master Load On/Off switch
- Individual Load Step Switches
- Fault condition smart indicators provide operator display and load disconnect during Overtemperature, and Load Dump
Automatic Load Dump circuit provides user interface provisions to the generator controls, automatic transfer switch, or building management system, to disconnect and disable all load steps from a normally closed (NC) set of auxiliary contacts. In the event of an actual power failure, all load bank load is removed from the source under test.
Remote Indication and Alarm contact closure [form-c-type normally open and normally closed] provides user interface to your building management system for indication, detection, and alarm of “Over-Temperature”, and “Load Dump”.
