Load Bank Rentals
3BW offers the best products to meet your company's needs.
The RML (Rack Mounted Load) of 8.75 kW is a resistive load equipment designed to precisely simulate the thermal dissipation and electrical consumption of IT equipment installed in racks, enabling the execution of controlled, safe, and repeatable tests in mission-critical environments. Installed directly in the standard 19″ rack, the RML enables validation of power and cooling infrastructure at the actual point of consumption, before servers and production equipment enter operation.
Resistive load banks developed and designed specifically to meet the needs of intermediate and advanced commissioning tests in Data Centers, being widely applicable to Integrated Systems Testing (IST), Site Acceptance Test (SAT), Pre-Commissioning, Equipment-Level Commissioning, and Subsystem Testing activities, normally associated with commissioning levels 3, 4, and 5.
These equipments enable safe, controlled, and stable simulation of electrical loads, essential for system validation. Modules with power ratings of 40 and 100 kW with capacity to operate at voltages up to 480V with frequencies from 50 to 400 Hz.
Small load banks in the range of 240 kW to 700 kW are equipment designed for controlled simulation of electrical load in low and medium power energy systems. Using predominantly resistive load, these banks enable safe and stable reproduction of real load behavior, being suitable for continuous, stepped, or stress regime tests. Developed for critical infrastructure applications, these equipments are robust, versatile, and capable of operating in both indoor and outdoor environments, supporting typical conditions of construction, commissioning, and maintenance.
Large load banks with capacities between 1,000 kW and up to 3,300 kVA with power factor 0.8 are designed for execution of high-power tests in critical electrical systems. Their modular architecture enables paralleling of multiple units, significantly expanding available total power and enabling tests in complex, redundant, and distributed systems. Equipment is designed for safe and reliable operation, supporting severe conditions typical of commissioning, acceptance tests, and prolonged stress testing.
Load banks with power factor control are equipment designed to simulate, in a precise and controlled manner, resistive and reactive loads, enabling adjustment of power factor according to the actual profile of electrical loads in the installation. Unlike purely resistive banks, these equipments enable application of loads with adjustable power factor, typically inductive or combined, reproducing with greater fidelity the behavior of IT systems, motors, power electronics, and non-linear loads present in critical environments. These banks can operate independently or in parallel with multiple units, expanding the power range and test complexity, being suitable for operation in outdoor environments.
NODUS is a control and monitoring system developed by 3BW for integrated operation of 3BW Load Bank model 100KW-HD, intended for scenarios where simultaneous management of large quantities of equipment is necessary. The system enables connection on a dedicated Wi-Fi network of up to 150 load banks, allowing centralized control and continuous monitoring during large-scale electrical and thermal testing operations. The connection and control module is integrated into the load bank so that, in case of communication or system failure, each equipment continues operating safely through its local panel, ensuring operational continuity of tests.
DC (Direct Current) load banks are equipment designed for controlled simulation of electrical loads in systems that operate exclusively in direct current voltage, enabling precise and stable application of current and power over extended periods. These banks are normally composed of high-precision resistive elements with fine load control, enabling tests at different voltage and current levels according to the system under evaluation. Mobile and modular equipment with the possibility of paralleling multiple units, expanding total test capacity. The equipment is designed for safe operation in indoor environments.
Read below some common questions related to our products. If your question remains, our specialists will be ready to assist you.
Yes, it is possible; however, step-down transformers will be required. The voltage will be reduced to 480V, allowing the test to be performed safely and accurately within the required parameters.
Yes, it is possible. However It is necessary to evaluate the specific characteristics, such as voltage, current, and the connection point—to identify the most effective equipment composition for the infrastructure in question.
Yes, this is a very common procedure. Nevertheless, it must be confirmed that the generators intended for testing are equipped to operate in parallel. If parallel operation is not possible, each generator will require a dedicated load bank for the duration of the test.
Yes, it is possible. However, several critical factors must be evaluated beforehand, including the total power to be tested, the specific installation site within the basement, and the overall duration of the test to ensure proper heat dissipation and safety.
Depending on the specific model, yes. Typically, our medium and large-capacity load banks are engineered for outdoor operation and are designed to function reliably even under rain conditions.
The duration of the test is determined by the specifications provided by the equipment or system manufacturer, or by the specific requirements outlined in the commissioning protocol.
Yes. Depending on the characteristics and requirements of the test performed, we can issue comprehensive technical reports documenting the results and observations.
