About Us

OptiCool Technologies is the sole industry supplier of two-phase pumped refrigerant cooling systems, supporting a wide variety of data center applications.

The Future is Hot. We Keep it Cool.

Traditional cooling solutions are inefficient and waste energy. At OptiCool, our mission is to build and deliver innovative, best-in-class cooling systems that solve today’s data center cooling challenges.

A Team of Cool Engineers

We are engineers who love cool tech. We love simple, elegant designs, and we love turning those designs into real-world products and solutions. Our design philosophy is driven by a focus on operational efficiency and eliminating energy waste.

Delta4T – our 4th generation cooling technology

OptiCool has rapidly accelerated the development of its groundbreaking Delta4T© technology. This progress has been made possible by leveraging our core team of engineers alongside more than 200 engineers and technicians from our parent company, Calvary Robotics. By integrating this collective expertise with advanced AI modeling software, we’ve effectively condensed years of development into a significantly shorter timeline.

The name Delta4T represents two core pillars of our innovation: Delta T, the temperature difference between supply and return water, a critical measure of cooling performance, and the fourth generation of our two-phase liquid cooling platform. This generation is purpose-built to handle both higher total heat capacities and dynamic fluctuations in the heat load.

What sets OptiCool apart is how we use refrigerant in the system. Unlike traditional cooling approaches that rely on refrigerant for compression cycles, we use it as the primary heat sink, allowing us to absorb and transfer heat more efficiently. Refrigerant’s superior thermal properties enable more effective cooling at lower energy consumption compared to single-phase water-based systems.

By using this more efficient cooling method, we are able to exceed the limits seen in traditional liquid cooling. That’s why Delta4T powers our industry-leading 120kW rear-door heat exchanger, a solution that demonstrates the full potential of high-capacity, energy-efficient thermal design.

Think Globally, Act Locally

We are dedicated to American-made technology and in-house manufacturing and assembly, backed by hands-on installation and support. We design, develop, manufacture, market and support our products in our headquarters and 250,000 ft2 manufacturing facility in Webster, New York. OptiCool is privately held and part of an industrial and mechanical engineering group of companies that includes Calvary Robotics and CGS Precision Technologies.
