Large Portable : Load Cube

  Load Cube 2500KW Load Bank System Overview

Simplex Load Banks - Load Cube Large Portable Load Bank

The Simplex Load Cube is an ultra-large capacity , fully portable, resistive/reactive Load Bank System intended for field use in testing, maintenance and performance proving of large generating systems. The Load Cube is rated 2500kw, 1875kvar at 400-600v commercial AC voltages. The Load Cube is typically used to test large diesel generators, turbines, paralleled generators and shipboard generators.

With a purpose-built design consisting of rugged, all-welded, tubular steel frame, heavy gauge steel sides, guarded hinged doors, power-operated ventilation louvers, the Load Cube is far superior to designs which use refurbished and modified ISO shipping containers. Four-sided access allows ready service of all components and facilitates the ultra-compact design.
