General Platinum Load Banks LLC has 20 years experience at designing load banks. Their products encompass a variety of Radiator Mounted stationary and portable Load Banks using high quality resistors and components. They have a convenient manufacturing location in Pittsburgh, PA.

First, they started with large load banks to test 3,000 HP (2,250 KW) locomotives. Later, they developed load banks for the diesel generator market.

Offering Standard and Customized Load Banks to meet your specific application:

Load Banks provide a self contained electrical load for testing purposes and prevent undesirable reliability conditions in back-up generating systems. Diesels typically perform best when run at 70-80% of rated KW capacity.  Load banks are used to reduce a condition called “wet-stacking” in which unburned fuel builds up within the engine exhaust, carbonize causing fuel injection issues, and other engine related fouling which occurs when the engine is run at no or very low loads. It is also used to comply with mission-critical facility codes such as NFPA 70 & 110 plus the Joint Commission on Accreditation of Health Care Organizations (JCAHO) for testing power systems.  For 100% load a stationary (permanently installed) self contained load bank is required rather than a radiator mounted design for routine exercising or testing of the generator.

A wide range of air-cooled sizes is available in single or three phase designs. Steps can be configured as required. Automatic load dump is a strongly recommended safety option and typically gets a signal from the transfer switch when a utility failure occurs and it transfers the building load to the generator it will turn off the load bank.

With multiple resistor element types at General Platinum Load Banks disposal, a reliable and efficient product tailored to your needs is always available. The unique ability to design and supply to your specifications is our advantage; a quality product delivered in a timely manner at a reasonable price.

The enclosure structure is available in aluminum, aluminized steel, galvanized steel, or stainless steel. A heavy-duty skeleton frame holds panels and equipment in place.

Radiator & Duct Mounted Load Banks: Using the engine’s radiator air flow for cooling the resistor elements, these load banks are suitable for use on stationary and portable generator sets. Dimensions are matched to your core making this a cost effective solution for periodic testing and minimizing “wet stacking”.

A radiator mounted load bank is specifically designed to mount in front of the radiator on diesel generator set that has an engine mounted radiator via a duct flange or direct mount. This custom size eliminates the time and cost of field modification. The fan attached to the engine of the genset should provide suitable airflow through the direct mounted radiator to cool the resistive elements. This is a more simplistic and economical solution since it requires no additional motorized cooling fans and associated components. It takes up of less space, is easier to install, emits less heat, has reduced air flow, quieter, and more cost effective.

Radiator Mount Load Banks can typically only be rated for a maximum of 50% of generated KW though some people say it can be rated up to 70%. The maximum restriction of cooling air (air intake to discharge side) on most the engine mounted radiators is on average 0.48”-0.50” H2O static pressure without overheating issues. It is sized to mate to the radiator dimensions. The duct flange is typically drilled in the field to reduce radiator bolt alignment issues and many times the dealer will add support bar stock to stiffen the combined assembly.

Many times with outdoor sound attenuated enclosures the “Radiator” Load Bank is mounted on the radiator exhaust hood/scoop of the enclosure.

Stationary Load Banks: Whether indoor or outdoor, purely resistive or resistive/reactive, a solution is readily available. Each model can be modified for a particular application, such as adding iron-core reactors, control power transformers, remote mountable controls, digital metering, lockable access doors, and a host of other possibilities. Alternatively, these banks may be trailer mounted for increased flexibility. Available in low and medium voltages, models range from 15 to 4000 kW, with reactive loading possible from 15 to 3000 kVAR.

Portable Load Banks: A complete line of portable load banks, ready for shipment when you need them. With their engineering experience and manufacturing capabilities combined with your application, we can have a custom designed product that will meet your particular needs. Hand carried, on casters or lifting channels, we have a solution for your requirement. AC load banks are available in a wide range of voltages and steps as is required for your particular application. DC load banks are also available. These unit can be offered with Master & Slave configurations to allow them to be strung together for greater output.

LOAD BANK models are available in many configurations...
