Accelsius Announces General Availability of NeuCool® IR150 and Launches NeuCool HyperStart Program at Data Center World 2026

WASHINGTON--(BUSINESS WIRE)--Apr 20, 2026--

Accelsius, the leader in two-phase, direct-to-chip liquid cooling technology for AI and high-performance computing, today announced the general availability of the NeuCool® IR150, the industry’s first fully integrated rack-level cooling solution that combines a two-phase Coolant Distribution Unit (CDU), 42U of IT rack space, and built-in liquid and vapor manifolds in a single 800mm-wide enclosure, offering up to 150kW of capacity.

Reimagined from the ground up for the liquid cooling era, the IR150 is a true plug-and-play system designed to move through established IT infrastructure channels, making two-phase liquid cooling accessible not just to hyperscalers but to enterprises and smaller operators for the first time. Its fully integrated form factor is perfect for edge deployments and the small language model workloads that will proliferate across the market as AI matures. The company also unveiled the NeuCool HyperStart program, a new initiative created to support hyperscale operators, neocloud providers, and key partners in validating two-phase direct-to-chip liquid cooling solutions and accelerating their readiness for high-density, large-scale deployments.

The announcements come at a pivotal moment for the data center industry. Hyperscale and neocloud operators are moving at unprecedented speed to bring gigawatt-class AI facilities online, and with that velocity has come increasing public scrutiny of power and water use in host communities. Billions of dollars in planned data center projects have already been delayed or blocked amid concerns about strain on local resources. Accelsius believes the industry can, and should, continue to move quickly—but responsible planning for more efficient AI factories also requires a hard look at waterless and more energy-efficient liquid cooling architectures from day one.

“Hyperscalers and neoclouds are under enormous pressure to deliver AI capacity faster than ever, and that urgency is understandable,” said Josh Claman, CEO of Accelsius. “Our message at Data Center World is simple: moving fast and planning responsibly are not mutually exclusive. With the general availability of the IR150 and the launch of NeuCool HyperStart, we’re giving operators a practical path to bring two-phase, direct-to-chip cooling into their reference designs today. That way AI factories can avoid the mistake of scaling without considering their host communities’ water and energy supplies.”

Traditional single-phase liquid cooling was the industry’s first attempt to move beyond air, but it was the wrong bet. These systems rely on treated water circulated directly to the chip, introducing leak risk, corrosion concerns, and continuous water-quality maintenance, and their complexity makes them nearly impossible to distribute through standard IT channels, keeping liquid cooling out of reach for all but the largest operators.

In contrast, Accelsius’ two-phase approach uses a non-conductive dielectric refrigerant with an A1 safety rating and low global warming potential. No water enters the IT rack, meaning leak events pose minimal risk to GPUs or server electronics. Industry studies have shown that two-phase cooling systems can reduce cooling energy consumption by up to 90 percent and eliminate millions of gallons of annual water use compared to air-cooled alternatives, while independent analysis by Jacobs Engineering has demonstrated that Accelsius’ two-phase solutions deliver 35–44 percent annual OpEx savings and 8–17 percent five-year total cost of ownership savings over single-phase direct-to-chip systems.

Introducing the NeuCool HyperStart Program

The NeuCool HyperStart program gives hyperscale operators, neocloud providers, and key partners a structured path to validate two-phase direct-to-chip liquid cooling—alongside complementary single-phase water cooling approaches—and bring these technologies into their data center reference designs and product roadmaps. Participants receive early engineering support, deployment planning, and technical validation to accelerate their readiness for high-density, large-scale AI deployments. Several hyperscale AI cloud providers have already engaged with Accelsius under the program as they build out cooling roadmaps for next-generation AI infrastructure.

The IR150 joins the NeuCool MR250, Accelsius’ row-based CDU delivering up to 250kW+ of cooling capacity per rack, and the NeuCool Thermal Simulation Rack (TSR), a first-of-its-kind thermal test platform. Together, the NeuCool product family offers operators a complete suite of two-phase, direct-to-chip cooling solutions that scale from evaluation through full data center deployment.

TOKYO (AP) — Japan on Monday issued an advisory for northern coastal areas for an increased risk of a possible mega-quake induced by a major quake earlier in the day.

The Cabinet Office and the Japan Meteorological Agency said there is 1% chance for a mega-quake occurring on the northern Japanese coast in the next week or so following the powerful quake earlier Monday near the Chishima trough.

Officials said the advisory is not a quake prediction but urged residents to raise their preparedness, such as emergency food and their grab bag just in case, while continuing their daily lives.

The advisory for the region is the second in recent months. One was issued following another major quake in December. No major subsequent quake occurred.

A powerful earthquake struck off the northern Japanese coast earlier Monday, and the Japan Meteorological Agency issued a tsunami alert in the region, sending residents to rush over to safer grounds. So far, no major injuries or damages have been reported.

The quake registering a preliminary magnitude of 7.5 occurred off the coast of Sanriku in northern Japan at around 4:53 p.m. (0753 GMT), at a depth of about 10 kilometers (6 miles), the agency said.

A tsunami of about 80 centimeters (2.6 feet) was detected at the Kuji port in the Iwate prefecture within one hour of the quake, and a smaller tsunami of 40 centimeters (1.3 feet) was recorded at another port in the prefecture, the agency said.

The tsunami alert and advisory were still in place in Japan, with warnings of a wave of up to 3 meters (10 feet), but the U.S.-based Pacific Tsunami Warning Center said the tsunami threat from the quake “has now passed.”

The Japanese agency urged residents in the region to immediately stay away from the coast or along rivers and take shelter on higher ground. It also cautioned people in the area against possible aftershocks for about a week.

Footage on NHK television showed many people driving up to parks and other facilities on higher ground. In the town of Tomakomai in Hokkaido, a resident came to a hilltop park after picking up his child at a cram school and said he planned to stay until the alert is lifted.

Iwate and three other northern prefectures issued non-binding evacuation advisories to more than 128,000 residents, according to the disaster management agency.

The Fire and Disaster Management Agency said officials are assessing the situation but so far no damage or injuries have been reported, including at power stations and other facilities.

The Nuclear Regulation Authority said nuclear power plants and related facilities in the region were all intact and no abnormalities were detected.

Another 7.5 magnitude quake in December left dozens injured.

It's 15 years since a magnitude 9.0 earthquake and tsunami on March 11, 2011, ravaged parts of northern Japan, caused more than 22,000 deaths and forced nearly half a million people to flee their homes, most of them due to tsunami damage.

Some 160,000 people fled their homes in Fukushima because of the radiation spewed from the tsunami-hit Fukushima Daiichi nuclear power plant. About 26,000 of them haven’t returned because they resettled elsewhere, their hometowns remain off-limits or they have lingering concerns about radiation.
