Data Center FAQs

A resistive load bank (1.0 power factor) primarily tests the engine’s ability to provide horsepower. However, data centers operate at a lagging power factor. To fully test the alternator’s capacity and the entire voltage regulation system, you need a resistive/reactive load bank. This allows you to simulate a 0.8 power factor, ensuring the generator can handle the “real-world” inductive loads found in modern facilities.

Not necessarily. C2C offers specialized Medium Voltage (MV) load banks that can connect directly to your loop (up to 33 kV). These units often feature integrated transformers and are designed for multi-megawatt projects, saving you the hassle and footprint of renting separate transformers.

For AC UPS systems, yes, our resistive or resistive/reactive units are perfect. However, if you need to test the DC battery strings directly, we offer dedicated DC Load Banks. These are compact, portable, and allow you to precisely validate battery autonomy without risking the critical load.

Boilers are cumbersome and dirty. Our Crestchic liquid-cooled load banks are designed specifically for data centers. They connect directly to your Technology Cooling System (TCS) or CDU loops. Unlike carbon-steel boilers which can introduce rust, our units use stainless steel construction to prevent contamination of your sensitive cooling loops. Availability of the equipment and the cost to run a high horse powered boiler can be very costly in fuel costs.

We recommend a hybrid testing approach. You can use our portable air-cooled resistive units to test the hot/cold aisle containment, while simultaneously deploying liquid-cooled units to validate the direct-to-chip or immersion cooling infrastructure. C2C can provide a single, centralized control solution to ramp these loads up and down in unison, simulating a “live” data center start-up.

Yes. Our DeepCoolAI units are engineered to mimic the extreme thermal dynamics of high-density compute (like NVIDIA GB200 racks). They allow you to verify flow rates, pressure drops, and heat rejection capacities at the exact temperatures your design calls for.

Absolutely. Level 5 IST is where C2C excels. We can deploy a massive fleet of load banks to simulate the total facility load—allowing you to “pull the plug” on utility power and verify that generators, UPS, and cooling systems all react correctly as a unified system. We ensure you validate the entire redundancy failover sequence before a single server is installed.

We offer flexible support models to fit your labor strategy. We can provide Operator-Free Rentals if you have the team, or Full-Service Execution where our technicians handle everything from logistics and cabling to running the actual test. We also offer onsite training if you want your team to learn how to operate the equipment safely.

We maintain a large rental fleet with same-day deployment options for urgent needs. Our “advanced replenishment systems” ensure we have inventory ready when your schedule compresses.

Yes. Our units can easily simulate ultra-high-density AI architectures. The Crestchic 600 kW liquid-cooled load bank delivers up to 600 kW of thermal simulation within a single footprint, while our 400 kW resistive air-cooled units provide 1 kW step resolution to replicate precise rack-level power draws.

Yes. Testing immersion requires validating two loops: the facility water loop and the dielectric tank itself.  Our load banks can be connected to the immersion tank to simulate load.

Each 600 kW liquid-cooled unit easily absorbs the thermal demand of an entire high-density, multi-rack row. With no minimum or maximum flow restrictions, the units adapt flexibly to any facility loop or CDU flow schedule. Controlling multiple units is seamless: using our VCS 2.0 platform, up to 240 air- and liquid-cooled load banks automatically discover one another over standard Ethernet daisy chains, allowing you to orchestrate and monitor an entire data hall from a single PC screen.

All wetted loops and hydraulic tanks are precision-welded and pressure-tested at up to 20.5 bar to ensure clean, closed-loop thermal transfer. In addition, VCS 2.0 provides real-time fluid conductivity monitoring to track fluid purity and help protect your CDUs from mineral and particulate contamination.

Not at all. The 600 kW unit uses full-bore, 4-inch (DN100) PN16 flanged connections engineered to minimize pressure drop. VCS 2.0 also tracks differential pressure and flow rates in real time, helping ensure that your loop dynamics remain fully balanced.

Each unit has an operating pressure rating of 8 bar and is pressure-tested to 20.5 bar. Safety features include a mechanical 9 bar pressure-relief valve, redundant fluid-temperature sensors, and automated low-flow and overpressure emergency cutoffs. In addition, integrated thermal-shock protection limits temperature changes to less than 0.5 °C/s, preventing cavitation and boiling inside the tank.

Deployment is fast and plug-and-play, using industry-standard STANAG quick-disconnect fittings compatible with standard site hoses. The fittings can also be removed for direct bolt-up to 4-inch PN16 flanges. The control network automatically discovers connected units over standard Ethernet cabling, with no manual IP setup required.

Rental boilers can introduce contamination, rust, and uncontrolled temperature swings that may foul new heat exchangers and delicate CDU microchannels. Crestchic liquid-cooled load banks provide clean, closed-loop thermal loading with precise ±0.5 °C Delta T control and built-in conductivity monitoring to help protect your loop’s fluid integrity.

Yes. In Delta T mode, the system automatically modulates the heating-element contactors to maintain your target temperature rise within ±0.5 °C, adjusting the applied power as the cooling distribution unit (CDU) increases or decreases flow rates.

Our VCS 2.0 control platform allows you to network and cluster up to 240 air-cooled (400 kW) and liquid-cooled (600 kW) load banks simultaneously over a single Ethernet daisy chain. From one central PC or handheld device, you can orchestrate multi-room hybrid test sequences and export unified compliance reports.
