Profile: N J Froment & Co. Ltd. is a manufacturer of load banks for testing power supplies and dynamometers for testing engine performance and agricultural stand-by generators. We are an BS EN ISO 9001:2000 certified company. Our product line includes load banks, dynamometers and PTO generators. Our Proof loader is a load bank system that replicates working load conditions and provides a rigorous test regime for power supplies from 1kW to many MVA. Load banks are available in static versions for permanent installation or movable format with fork lift pocket base, castors or full road going trailers. Larger load banks, typically above 1200kVA, are based on an ISO container construction. Our inductive (or inductive reactive) load banks are used in conjunction with resistive load banks for testing AC supplies at non unity power factors. Most generating sets are rated at 0.8 power factor (or CosO), so to test at rated conditions requires both resistive and inductive load. Inductive load banks can be customized for a particular application, or they can be combined into one unit with resistive load banks.
