Titan 600R Load Bank Rental

Simplex Stationary Load Banks can be used to satisfy the requirements of the National Fire Protection Association (NFPA) for emergency stand-by power systems. These requirements concern acceptance testing and periodic on-site testing and maintenance of emergency and stand-by power systems.

The essence of the requirements is that emergency and stand-by power systems are to be tested under load.

• NFPA 110 - Emergency and Standby Power Systems, Sections 5-13, 6-3, 6-4
• NFPA 99 - Health Care Facilities, Section 3-4.4.1.1 (b)
• NFPA 70 - National Electric Code, Section 700-4 (b)

• Simplex Load Banks utilize UL rated, industry leading "Powr-Web" load elements specifically designed for load banks.


• The "Powr-Web" elements are conservatively operated at half the maximum temperature rating of the alloy and features a short-circuit-safe design based on continuous mechanical support of the resistor by high temperature, ceramic clad stainless steel rods.


• "Powr-Webs" are assembled into discrete trays which are inserted into a vertical "stack." Each tray in the "stack" is independently serviceable without disturbing adjacent trays.

• Fan directly driven or belt driven, depending on Load Bank model
• Fan blade, shrouded for high efficiency
• Fan motors normally operate at load bank line voltage
• Motors for outdoor load banks are totally enclosed
• Motor control contactor

The load of a Resistive Load Bank consists of a dense array of open, uninsulated power resistors mounted within a cooling air stream. Since the elements are electrically live, it is possible for a foreign object to penetrate the element array and create a short circuit of adjacent elements or a short to ground.

Since the elements are densely packed, it is possible for a short circuit, once started, to rapidly propagate through the entire element array. As a Load Bank represents a relatively large amount of power concentrated within a relatively small volume, a self-propagating, cascading short circuit would have catastrophic results.

Simplex virtually eliminates the dangers of short circuit through the use of branch circuit fuse protection of the load elements. Per NEC 110-10, protective devices shall clear a fault without "extensive damage" to the circuit components.

A Simplex Load Bank is divided into branch circuits of not more than 50 KW each.
