LIQUID LOAD
BANK

Revolutionizing Commissioning
for Liquid Load Banks

Delivering comprehensive test solutions for mission-critical data centers in the AI era.

Offered in partnership with Liquid Load Banks, this next-generation load bank is engineered to validate high-density compute infrastructure by rigorously testing electrical and mechanical systems in new mission-critical facilities. Manufactured by Air2O using Liquid Load Banks’ patent-pending design, it supports 500kW at 415V and up to 670kW at 480V—delivering robust, reliable, and repeatable performance for commissioning data centers and other critical environments.
“This partnership is built on exceptional engineering and a profound belief in each other’s respective areas of expertise,” said Sullivan. “Data center operators are assured of a comprehensive cooling and testing solution manufactured to the highest standards, helping them expand their capabilities for the AI era.”

Purpose-built for comprehensive commissioning, the LLB 670 ensures full validation of UPS systems, Technology Cooling Systems (TCS), and Technology Water Distribution Systems (TWDS). By simulating real-world load conditions, it verifies system performance, resilience, and reliability before going live.

Fully compliant with Open Compute Project (OCP) guidelines for water based transfer fluids in single phase, cold plate-based liquid cooled racks, the LLB 670 is constructed with 316 Stainless Steel and INCOLOY 800 components to mitigate the risk of chloride crevice corrosion, ensuring long-term durability in demanding environments.

Engineered with multiple automatic protections, the LLB 670 features automatic shutdown mechanisms for minimum flow per kW, maximum temperature, and maximum pressure. These safeguards ensure the safe operation of both the load bank and the infrastructure under test, preventing potential failures during commissioning.

The LLB 670 is equipped with advanced instrumentation, providing precise mechanical and electrical measurements that enable data centers to validate performance against their Service Level Agreements (SLAs). Mechanical parameters include input and output fluid temperature, input and output fluid pressure, and fluid flow rate, while electrical monitoring captures power (kW), current (Amps), and frequency (Hz). This high-fidelity data ensures accurate system testing, helping facilities meet operational and reliability commitments.
