Company profile
researched Aug 2026Actasys is a thermal management technology company whose ActaJet product provides targeted ("spot-on") cooling for components inside high-density data center server racks. The system is aimed at high-rate data transfer and processing hardware, including Network Interface Cards (NICs), Data Processing Units (DPUs) and switches, with the stated goal of maintaining an operating thermal environment suitable for AI and other computationally intensive workloads.
The company positions ActaJet as an integrated cooling solution for two main application areas. The first is communication networking, where increasing data speeds cause overheating in optical cables and server ports, which the company describes as a bottleneck limiting data center scalability; ActaJet is intended to remove overheating at cable ports. The second is printed circuit boards, where the space available for cooling shrinks as CPUs, memory modules and other processing elements are packed more densely; small-form actuators are used to cool specific points, which the company says allows CPUs to operate under high ambient temperatures and enables denser stacking of PCBs.
▸Full profile — market position, technology, go-to-market
Market position
Actasys addresses data center thermal management, focusing on component-level air-jet cooling for networking and processing hardware rather than broader facility cooling approaches.
The company emphasizes a combination of very thin form factor (under 3 mm), low power draw (2-3 W), high-velocity turbulent air jets (up to 80 m/s) and software-based dynamic control, allowing cooling to be directed at specific components such as NICs, DPUs and switches within existing 1U/2U server racks.
Technology
ActaJet uses turbulent air jets reaching velocities of up to 80 m/s to deliver localized cooling. The actuators are less than 3 mm thick, which the company states makes them suitable for 1U and 2U dense server environments, and consume only 2-3 W of power. The system is software-driven and adjusts cooling dynamically in response to demand. Deployment relies on small-form actuators placed near heat-generating components rather than rack- or room-level cooling.
Go-to-market
The company markets ActaJet directly through its website, which invites prospective data center customers to make contact for cooling-efficiency engagements.
Data center operators and owners of high-density server infrastructure running artificial intelligence and high-rate data processing workloads, including those constrained by thermal limits at network ports, optical cables and densely populated printed circuit boards.
