Infinium EDGE ETV100™ Immersion Fluid Earns NSF PFAS-Free Certification and HT1 Registration as Food Safe

Independent NSF review confirms the fluid behind Infinium Edge™ immersion cooling is food safe and is not PFAS chemistry, unlike the "forever chemicals" found in some earlier generations of immersion fluids.

SACRAMENTO, Calif., Nov. 9, 2026 /PRNewswire/ -- Infinium today announced that NSF International has registered Infinium EDGE ETV100™ Immersion Fluid in Category HT1 for heat transfer applications where incidental food contact may occur, and certified it PFAS-Free under NSF Certification Guideline 537, confirming that ETV100 is not PFAS chemistry. ETV100 now meets the same NSF requirements applied to heat transfer fluids used in food and beverage processing plants.

ETV100 powers Infinium Edge's immersion cooling systems, including Vector ONE™ modules deployed through the community-friendly EdgeSites™ program, which leverage existing buildings and power and zero freshwater for cooling to host AI infrastructure. The credentials back up claims through independent verification of the fluid's food safe and PFAS-free chemistry. This provides AI companies and data center operators with documentation to support selection of fluids that are safe and effective for increasingly dense AI hardware and environmental due diligence.

NSF's Category HT1 registration for heat transfer fluids is the designation food and beverage manufacturers rely on when selecting fluids that may come into incidental contact with food. To earn it, NSF reviews the fluid's formulation and labeling against applicable U.S. FDA regulations (21 CFR). For data center operators and host communities, it provides a trusted, independent benchmark for the fluid inside their cooling systems.

Communities hosting data centers deserve clear information about the materials used in their cooling systems. Some earlier immersion fluids, particularly in two-phase systems, relied on fluorinated chemistries, a class of substances commonly known as "forever chemicals" because they persist in the environment for decades. ETV100's PFAS-Free certification confirms it contains no forever chemicals. ETV100 is a synthetic hydrocarbon fluid produced through Infinium's Fischer-Tropsch process, with no fluorinated compounds by design, and NSF verified it against defined requirements: no more than 50 ppm total organic fluorine and no intentionally added PFAS, PFAS additives, post-consumer recycled content or PFAS from manufacturing contamination.

"AI infrastructure earns community trust through the choices we make—from the buildings we reuse to the fluids we put inside them," said Robert Schuetzle, CEO of Infinium. "Our EdgeSites program transforms existing commercial and industrial buildings into energy-efficient AI data centers using waterless immersion cooling. NSF's independent verification confirms that the fluid in our systems is food safe and is not PFAS chemistry, giving communities and AI companies evidence they can trust."

"By registering its product to NSF International's Nonfood Compounds Program, Infinium has proven its commitment to public health and safety," said Orsi Dezsi, Business Unit Manager for nonfood compounds at NSF International. "Their registration with NSF International verifies that the product meets the category requirements and is therefore acceptable to be used in food processing and food handling facilities."
