Options Tech Debuts Waterless Two-Phase Cooling for Finance

Options Technology announced a sealed, waterless two-phase refrigerant cooling system aimed at on-premises and edge data centers used by banks, trading firms and payment processors. The system delivers closed-loop refrigerant cooling directly at the server and rack level to address rising compute density.

The cooling loop is sealed and filled with a dielectric refrigerant. At the server cold plate the refrigerant absorbs heat and changes from liquid to gas; the vapor then moves to an external heat exchanger where it condenses and releases heat. The loop transfers latent heat without circulating potable water inside the data hall.

Options Technology described the design as targeted at trading floors, risk-management clusters and other finance-sector installations that need steady temperatures, low latency and high uptime. Integration options include rack-mounted cold plates, centralized condensers or facility-level dry-cooler heat rejection, and controls that monitor refrigerant pressure and temperature. The packaged system connects to existing server hardware via cold-plate adapters and is intended to replace row- or room-level air cooling without requiring immersion in dielectric baths.

Two-phase cooling keeps the cold plate at a nearly constant temperature because the refrigerant changes phase at the heat source. That phase change improves heat transfer compared with single-phase liquid cooling and air systems. Closed two-phase loops produce more uniform component temperatures across CPUs and accelerators and can support higher wattage per rack than air-cooled designs.

The sealed refrigerant loop removes the need for facility potable-water hookups and reduces the chance of water-related damage inside server cabinets by eliminating open-water circuits in the data hall. The system requires leak-detection capabilities, defined service protocols and trained technicians to maintain reliability over time.

Financial data centers face growing demand for compute from algorithmic trading, risk analytics and real-time market data processing. Operators evaluating two-phase cooling must assess hardware compatibility, the availability of trained service personnel, refrigerant management plans, and the upfront capital and integration work needed.

The industry is shifting to liquid cooling across high-performance computing and enterprise data centers, with options that include rear-door heat exchangers, single-phase liquid systems and full immersion cooling. Two-phase systems offer steady-state temperature control and can improve energy efficiency compared with air cooling, while requiring different maintenance and operational practices.
