Total Facility Validation from the Utility Feed to the AI Rack.
In a mission-critical environment, your infrastructure is only as reliable as its most recent stress test. Load bank testing provides essential validation across the entire power chain. For example, it confirms that standby generators and UPS systems transition smoothly during a utility failure. It also verifies that the cooling plant can reject heat loads at full capacity.
By simulating the electrical and thermal demands of traditional enterprise servers and high-density AI clusters, our solutions uncover hidden vulnerabilities before they lead to costly outages. Furthermore, whether commissioning a new build or performing routine maintenance, we deliver the empirical proof that backup systems and cooling loops will perform when they are needed most.
The Exterior Power Plant
Medium Voltage Commissioning
Direct connect medium voltage load banks are provided to support commissioning up to 33 kV. As a result, substations and high voltage distribution loops can be tested directly. This allows the primary utility connection to be commissioned without the added complexity of multiple step down transformers.
Hyperscale Generator Testing
The fleet includes large 6.25 MVA resistive reactive containers designed to test generator sets under realistic operating conditions. These units allow testing at a true 0.8 power factor. Therefore, alternators and voltage regulators perform correctly under real world electromagnetic loads.
All Weather Reliability
Generator yards operate outdoors and must perform in all conditions. These units feature IP55 rated enclosures and stainless steel elements designed to operate reliably in extreme environments. For instance, they function well from desert conditions to Antarctic climates.
The White Space
Air Cooled Testing
Portable resistive load banks ranging from 100 kW to 500 kW are used to emulate the resistive heat load generated by server racks. When placed in hot aisles, these units generate precise heat loads that allow cooling infrastructure to be tested under realistic conditions. As a result, airflow dynamics, hot and cold aisle containment, and overall HVAC performance can be validated. This also stress tests the power ecosystem to ensure it can deliver the high density power required to operate IT infrastructure reliably.
High Density Liquid Cooled Testing
Water cooled load banks rated at 500 kW connect directly to coolant distribution units to verify flow rates, pressure drops, and heat rejection capacity within the primary cooling loop. Meanwhile, hybrid rack validation is supported through a single chassis design that integrates 100 kW of air cooling and 150 kW of liquid cooling. This approach allows modern AI racks that rely on liquid cooling for GPUs and air cooling for switches to be tested simultaneously. For sensitive direct to chip environments, stainless steel wetted components ensure zero contamination enters the cooling system. Therefore, loop integrity and long term performance are protected.
Critical Power Systems
Backup power systems must be mission ready before a facility goes live. Resistive and resistive reactive load banks are deployed to simulate realistic electrical loads and lagging power conditions. This ensures generators and upstream power systems perform as required under real operating scenarios
Battery autonomy testing is supported through specialized DC load banks that validate battery systems and backup power sources against required discharge times. In addition, resistive load banks are used for UPS burn in testing. This process allows steady state heat runs to verify efficiency and thermal stability before systems are placed into service.
