Immersion cooling firm GRC has announced a new cooling distribution unit (CDU) and a new immersion system for Edge deployments.

GRC announces ICEraQ Nano

The company this week announced ICEraQ Nano, a new liquid-to-air immersion cooling rack system purpose-built for Edge deployments in small data rooms and communications closets.

The stand-alone liquid-to-air cooled rack delivers 13kW of cooling without chilled water and offers 10U of immersion-cooled space, cooling with 340 liters of dielectric fluid.

The Nano ships pre-filled with ElectroSafe fluid and features an integrated liquid-to-air heat exchanger. The company said the system features an automated fluid management system, server lift mechanism, and top-mounted service tray for server maintenance.

“The ICEraQ Nano delivers immersion cooling that addresses high-density challenges customers are now facing,” said Peter Poulin, CEO of GRC. “By eliminating the need for chilled water and simplifying overall deployment, the Nano delivers high-performance cooling for Edge computing.”

On LinkedIn, Poulin added that the ICEraQ Nano was the first product to come from the company’s engineering alliance with Cisco.

GRC releases new CDU

This month also saw GRC announce the launch of the ReliaSys IR500 CDU.

The system, designed for direct liquid cooling (DLC) and rear door heat exchanger (RDHX) deployments, delivers up to 500kW of cooling capacity.

“Direct liquid cooling is transforming how data centers are built and operated,” said GRC CEO Poulin. “With the ReliaSys IR500, we’re giving operators a powerful, reliable CDU that maximizes performance and efficiency in high-density deployments.”

GRC partners with Endor for gigawatt-scale data centers

GRC was founded as Green Revolution Cooling in 2009 and provides single-phase immersion cooling technologies. It services both GPU and cryptomining applications, and claims deployments in 22 countries globally. Earlier this year, it secured investment from Samsung Ventures.

November also saw GRC announce a partnership with Endor Development to develop and deploy “innovative immersion cooling solutions for giga-scale AI data centers that meet the demanding cooling needs of AI factories.”

Together, the companies aim to develop immersion cooling solutions for data center reference designs, total cost of ownership and return on investment tools, and warranties in partnership with server and dielectric fluid OEMs.

Endor is described as a stealth startup developing sustainable AI data centers. The companies said multiple AI data center contracts are in place today, with first deployments expected to go live in the second half of 2026.

“Air cooling may be sufficient for lower-density data centers. However, high-density AI data centers require a more innovative and energy-efficient approach that will handle the heat, protect the servers, and free up the power that would otherwise be consumed by conventional cooling technologies. Immersion cooling delivers those benefits,” said GRC’s Poulin.

“In our experience, our closed-loop immersion cooling solution designs for our AI data centers optimize value with sustainable power usage efficiency for our customers and their communities,” added Jake Smith, CEO of Endor Development.

Smith was formerly at Intel for 24 years as senior director of developer production solutions and director of data center solutions and technologies. He has previously said Endor is targeting facilities in Brazil (in Uberlândia with RT-One), Mexico, the US, and Canada.
