Heat transfer fluids for high-density environments

Efficient and reliable liquid cooling for data centres

With the rapid expansion of data storage and processing needs, data centres face a growing challenge: how to manage heat generation without compromising uptime, energy efficiency, or environmental compliance. As server density and power consumption increase, so does the demand for effective and sustainable cooling.

Closed-loop liquid cooling systems offer precision and high-performance, provided they use the right heat transfer fluid. For data centres operating near sensitive water sources or under strict environmental regulations, fluid safety is just as critical as thermal efficiency.

Fluid technology for mission-critical cooling

Kilfrost’s heat transfer fluids are engineered to meet the exacting requirements of modern data centres. Our ALV (Advanced Low Viscosity) range delivers high thermal performance and energy efficiency, with the added benefit of being non-toxic and biodegradable. Formulated with bio-derived base materials classified as GRAS (Generally Recognised as Safe) by the FDA, Kilfrost ALV represents a step-change from traditional glycols, offering improved pumping and heat transfer efficiency. Lower viscosity reduces system resistance and energy demand, resulting in lower operating costs and better long-term system performance.

Kilfrost ALV also provides exceptional protection against corrosion, tested to and exceeding the ASTM D1384-05 standard, helping safeguard valuable cooling infrastructure and extend equipment lifespan.

Free from harmful additives such as nitrates, nitrites, borates, and heavy metals, it’s a fluid solution built with both operational resilience and environmental responsibility in mind.

Designed for data centre demands

Whether you’re planning a next-generation facility or optimising your current cooling infrastructure, Kilfrost’s heat transfer fluids offer high-performance, safety, and environmental integrity. They are helping data centre operators around the world protect critical hardware and support sustainability goals without compromising on cooling capability.
