Resistive Loadbanks
A Resistive load applied at a power factor of 1.0 (unity), provides stable and accurate load to prove engine output at the point of build or commissioning. Resistive loadbanks can also be used to keep engines in peak condition where the actual applied load is lower than the output of the engine. To avoid excessive carbon build-up and the associated oil pressure and turbo-charger problems, a regular resistive load is a cost effective way to protect power generation assets.

Crestchic design and manufacture a wide range of air-cooled resistive loadbanks in standard frames sizes & containers, from 10kW to 7000kW, built to your specific voltage, frequency and phase requirements. All our loadbanks employ stainless steel finned elements for maximum heat dissipation and durability. In addition we are also able to offer a tailor-made service and will design and build a Resistive loadbank to any size, at any voltage and frequency, to meet customer specific applications.
