Resistive-Reactive Loadbanks
A Resistive-Reactive Loadbank allows testing at conditions replicating a lagging power factor and ensures complete engine and alternator testing. Many Generators and Turbines are rated at around 0.8pf and therefore can only be fully tested at 100% nameplate rating by utilizing a Resistive-Reactive loadbank. Crestchic offers both Combined Resistive-Reactive or Reactive only Loadbanks.

Crestchic design and manufacture a wide range of fixed or variable power factor Resistive-Reactive Loadbanks in standard frames sizes & containers, from 50kVA to 6250kVA, built to your specific voltage, frequency and phase requirements. All our loadbanks employ stainless steel finned elements for maximum heat dissipation and durability.
