The Simplex LBW Water-Cooled Resistive Load Bank is completely quiet, highly compact, and virtually maintenance free - offering a highly attractive alternative to traditional air-cooled units. The LBW-Series consists of an assembly of high-pressure load cells in a structural steel tubing frame, clad with steel panels. Coolant flow is via intake and exhaust manifolds with feeder lines to each load cell. Coolant flow is controlled by a main electrically operated valve.


  • Variety of Cooling Media: City water (nominal 50PSI), closed loop chilled water systems, heat exchanger systems, pumped water from natural sources (lake, river, etc.) or brine or sea water (requires optional nickel alloy construction and elements).
  • Numerous Applications: Ideal for installation in buildings in central-city areas, industrial parks or office complexes where an outdoor air-cooled unit would be architecturally obtrusive or impossible to install due to space or noise restrictions.
  • Limited Temperature Rise - High Flow Rate Systems: Available for use with chilled water systems. These Load Banks limit temperature rise to a nominal 12.5°F and consequently accept very high flow rates (50 GPM per 100KW).
  • Standard System Controls: The Simplex D-Series Digital Controller is PLC-based, network capable, and comes with a local or remote color TFT touch-screen operator interface.
  • Load Elements: Water-immersion type, screw-plug mounting.
  • Coolant Flow Control: Main electrically operated valve.
  • Water Connections: 2”, 4” or 6” as required by flow.
  • System Protections: Sensors, alarms (alarm message on remote operator interface terminal), lock-outs as appropriate, for the following: overpressure, over-temperature, low coolant level, loss-of-flow.
  • Load Circuit Protection: Branch circuit fuses. One set of fuses each 50KW branch. Fuses are current limiting type, 200,000 AIC, 600V, enabling safe use on large generating or UPS system.
  • Load Control: 3-pole magnetic contactors.
  • Control Power: 120V internal, transformer isolated.
  • Load Connection: Load source hard wired to load bank via 3-phase main copper load bus. Field power connections are made to the bus.
  • Connections: Control Wiring - 105°C, color coded; Power wiring - 150°C XLP color-coded.
  • Enclosure: Low profile, rugged, portable design.
  • National Fire Protection Association (NFPA): Satisfies the requirements for emergency stand-by power systems.
