Direct air cooling

Precision engineered air optimisers deliver advanced direct air-cooling and top-tier Power Usage Effectiveness (PUE). Direct air cooling offers an eco-friendly, Tier III compliant solution is highly efficient and versatile.

Pioneering excellence

Leveraging filtered outside air directly, we eliminate complex mechanical cooling systems and unlock near 100% free cooling. This approach dramatically lowers energy consumption, supports IT loads up to 50kW per rack, and fosters a trust-inspiring balance of performance, adaptability, and environmental responsibility.

Next-Generation Liquid Cooling

Ark leverages cutting-edge liquid cooling technology to deliver highly efficient, scalable, and sustainable data centre cooling. By prioritising free cooling and minimising reliance on mechanical systems, our approach ensures optimal heat rejection and maximised IT performance.

  • Efficient & Scalable: Liquid Optimisers (LOs) enable flexible cooling capacity, adapting to client needs and multi-storey deployments.
  • Sustainable & Cost-Effective: Reduced mechanical cooling lowers energy consumption while supporting rainwater harvesting.
  • Optimised Performance: Keeping cooling close to IT minimises airflow inefficiencies, enhances site acoustics, and maximises system reliability.

Innovations

Ark has been at the forefront of technological innovation since 2010, driving carbon reduction through sustainable operations and design. Our data centres leverage modular metal construction, enabling reusability and adaptability while minimising waste. Innovating further, we’ve integrated rainwater harvesting systems at many sites to support cooling operations and reduce water wastage, ensuring our facilities are as efficient as they are environmentally responsible
