Load Banks are devices designed to provide electrical loads for testing power sources such as generators and Uninterruptible Power Supplies (UPS). Load Banks are also used to reduce "wet stacking" problems in diesel engines of backup generating systems.

Most Avtron resistive load banks feature Helidyne (TM) resistive elements. These Avtron designed and manufactured elements are made of a corrosion resistant chromium alloy and are fully supported across their entire length on stainless steel support rods with segmented ceramic insulators. Elements are carefully selected to operate at low temperatures to provide extended, reliable performance, eliminating the need for a "cool down" period after load bank operation.

Helidyne (TM) is a trademark of Avtron LoadBank, Inc.

Applications Ordering

Load banks can be used in a wide variety of applications, such as:

  • Factory testing of engine generator sets
  • To reduce "wet stacking" problems
  • Periodic exercising of stand-by engine generator sets
  • UPS system testing
  • Battery system testing
  • Ground power testing
  • Load optimization in prime power applications
  • Factory testing of turbines

Avtron manufactures both the load banks and the auxiliary equipment necessary to handle these and other applications. Contact your Avtron sales representative for complete support in choosing the best load bank system for your requirements.

Improve Reliability of Generator Set
Industry trade organizations and manufacturers both agree that a well planned preventive maintenance program is vital to the reliable operation of a standby generator. Load Banks are an essential part of such a program. Load Banks provide a practical means to test the system without interruption to the critical loads.

The primary cause of diesel engine failure is "wet-stacking" ("wet" unburned fuel accumulating in the engine "stack"). It is caused by under-loading of the generator. Diesel engines that are lightly loaded, or allowed to idle for long periods, never reach their recommended operating temperature. Over time, unburned fuel coats the combustion chamber, reducing engine rating, efficiency, and life span. A preventive maintenance plan that includes load testing of a diesel generator set, will reduce the harmful effects of "wet-stacking" and increase engine life.
