Infinium’s ETV100 immersion fluid earns NSF PFAS-free certification
Infinium’s ETV100 immersion fluid has received NSF International registration for heat transfer applications where incidental food contact may occur, alongside certification that it is PFAS-free. The company says the independent credentials give AI companies, data center operators and host communities documentation about the fluid used in its cooling systems.
- NSF registered ETV100 in Category HT1 for incidental food contact applications.
- NSF certified ETV100 PFAS-free under Guideline 537.
- Infinium says the fluid has no intentionally added PFAS or fluorinated compounds by design.
- ETV100 powers Infinium Edge immersion cooling systems and Vector ONE modules.
NSF registers ETV100 for HT1 applications
NSF International registered Infinium EDGE ETV100 Immersion Fluid in Category HT1 for heat transfer applications where incidental food contact may occur. The registration means the fluid meets the NSF requirements applied to heat transfer fluids used in food and beverage processing plants, according to Infinium.
NSF reviews a fluid’s formulation and labeling against applicable U.S. FDA regulations under 21 CFR for this category. NSF International said the registration verifies that ETV100 meets the category requirements and is acceptable for use in food processing and food handling facilities.
The registration appears in the NSF White Book under Registration No. 174592. Infinium also listed certificates C0911923-01 for Infinium Edge Operations in Sacramento, California, and C0911930-01 for its Corpus Christi, Texas facility.
Certification addresses PFAS concerns
NSF certified ETV100 under Certification Guideline 537 as PFAS-free. Infinium says the certification confirms that the fluid is not PFAS chemistry and contains no intentionally added PFAS, PFAS additives, post-consumer recycled content or PFAS from manufacturing contamination.
Under the defined requirements cited by the company, the fluid must contain no more than 50 ppm total organic fluorine. Infinium describes ETV100 as a synthetic hydrocarbon fluid produced through its Fischer-Tropsch process, with no fluorinated compounds by design.
The announcement contrasts ETV100 with some earlier immersion fluids, particularly those used in two-phase systems, that relied on fluorinated chemistries. Those substances are commonly known as “forever chemicals” because they persist in the environment for decades, according to Infinium.
What the credentials mean for Infinium Edge
ETV100 fluids power Infinium Edge’s immersion cooling systems, including Vector ONE modules deployed through the company’s EdgeSites program. Infinium says the program uses existing buildings and power, along with zero freshwater for cooling, to host AI infrastructure.
The company is positioning the NSF documentation as a tool for AI companies and data center operators evaluating fluids for increasingly dense AI hardware and environmental due diligence. For communities hosting data centers, Infinium says the registration provides an independent benchmark for the material inside cooling systems.
“NSF’s independent verification confirms that the fluid in our systems is food safe and is not PFAS chemistry,” Infinium CEO Robert Schuetzle said. The company describes Infinium Edge as an AI data center infrastructure platform built around single-phase immersion cooling, including thermal management, modular AI Factory units, monitoring systems and EdgeSites data centers in existing powered buildings.
