OCP CE - ACF Cold Plate Sub-Project Call (Feb 11, 2026)

Why It Matters

Finalizing coolant and cold‑plate specifications and integrating oxygen‑removal technology will streamline data‑center cooling, cut OPEX, and accelerate industry‑wide standardization.

Key Takeaways

• AMIA summit presentation deadlines set for March 2 and March 23
• PG25 coolant fluid base spec and guidelines nearing final submission
• Cold‑plate specification documents moved to OCP formatting for approval
• Watts system removes dissolved oxygen, cutting corrosion and chemical costs
• Volunteer needed to update corporate requirements document after recent changes

Summary

The OCP Community Engineering call on February 11 focused on progress updates for the ACF Cold Plate sub‑project and upcoming community events. Organizers reminded participants of the AMIA summit timeline, with presentation proposals due March 2 and final slides due March 23, and solicited volunteers to revise the corporate requirements document that has become outdated. Key work‑stream updates included the near‑completion of the PG25 coolant‑fluid base specification and its accompanying guidelines, both awaiting final review before submission. The cold‑plate specification has been transferred into OCP‑standard formatting and is slated for submission shortly, while BMQC’s EPDM evaluation and PBMC’s design‑spec testing remain on track for Q1 completion and an EU summit presentation in April. Guest speaker Alex Green from Watts Water Technologies presented a proprietary three‑part filtration system that strips dissolved oxygen from closed‑loop cooling circuits, reducing levels to under 1 ppm and eliminating corrosion and microbial growth. The solution promises up to 20‑year media life for oxygen removal and 7‑year life for sediment filters, potentially removing the need for glycol‑based chemicals and delivering energy savings. If adopted, these standards and the Watts technology could simplify data‑center cooling architectures, lower operational expenditures, and accelerate industry consensus on material compatibility and fluid quality, while the call also highlighted community needs for sponsorship and volunteer leadership to sustain momentum.
