Liquid cooling firm Accelsius has launched a new cooling support program that provides insurance against leak damage.
The two-phase, direct-to-chip liquid cooling provider has launched NeuGuard, a new support program. It offers a range of standard and optional support and white-glove professional services.
Backed by CNA, one of the largest US warranty insurers, NeuGuard offers a custom multi-year warranty, flexible support, and up to $100,000 per rack coverage for internal damage from NeuCool leaks.
Accelsius said CNA has developed a custom multi-year warranty program based on the NeuCool system.
“Protecting critical computing infrastructure is more important than ever,” said Jeff Manuel, vice president of underwriting for CNA warranty & alternative risks. “Our tailored insurance underwriting and program coverage for NeuGuard demonstrate our commitment to addressing the evolving needs of the data center industry.”
Accelsius also now offers server-level warranties for leading OEMs globally. Following testing and validation by key OEM providers, SKU-level warranties are being introduced, offering client coverage alongside the NeuGuard offering.
Texas-based Accelsius was founded in 2022 by Innventure LLC. The company is commercializing technology developed by Nokia's Bell Labs. Accelsius’ NeuCool technology had been developed for five years by Bell Labs, but not productized. No Bell Labs staff came to Accelsius.
NeuCool’s system sees vaporators (also known as cold plates) mounted directly to targeted hot-spot chips. Dielectric refrigerant flows through the vaporators, where it nucleates into a vapor, which then travels to a CDU and condenses back into a liquid in a closed-loop system, then returning to the vaporator for additional cooling.
Direct-to-chip systems usually rely on water, which has a high heat capacity, but Accelsius is using a dielectric coolant, and allowing it to boil in the circulating system, to remove more heat.
