Vaporator

Best-in-Class Technology

Our two-phase, direct-to-chip platform enables cooling of 1500W+ per socket 

NeuCool has an industry-leading 0.020°C/W thermal resistance at a 700W+ TDP (H100 GPU).

We use a waterless, low-pressure, non-forever dielectric refrigerant with zero Ozone Depletion Potential (ODP).

Mission-Critical Design

The NeuCool system is built to last — with the most robust and reliable materials and components — prioritizing maximum uptime, ease of deployment, and serviceability by onsite technicians — greatly reducing the need for special training.

Resiliency is designed-in with redundant, hot-swappable power supplies, sensors, pumps and core logic board.

We pride ourselves on leak avoidance. The engineered refrigerant we use will not cause damage to IT equipment. And our redundant leak detection sensors and mitigation protocols add even more protection.

US Manufacturing

North American-Based Operations

85% of our Tier 1 vendors are based in North America, near our US-based R&D and manufacturing.

Keeping our supply chain close means faster lead times, ability to scale for large volume orders, superior quality and traceability plus reduced logistics costs.

Most importantly, our operational model is built to respond quickly – to customer needs, market developments and global supply conditions.
