Australia’s data centre and cloud hosting sector is experiencing rapid growth, driven by digital transformation, the explosion of e-commerce, and the rise of artificial intelligence (AI) and machine learning. According to IBIS 2025 industry report, their forecasts indicate the industry will grow at an annualised rate of 9.7% from 2025 to 2030, reaching $6 billion by 2030, making it one of the fastest-growing sectors in the Australian economy.1
As demand for secure, scalable, and energy-efficient IT infrastructure continues to surge, data centre operators face the increasing challenge of efficiently cooling high-density server environments.
Traditional air-cooling methods are reaching their limits, especially as next-generation AI deployments push rack power densities beyond 100 kW. To address these challenges, the industry is embracing advanced liquid cooling technologies.
Why Liquid Cooling for Data Centres?
- 20-50% greater energy efficiency vs. air-cooled systems
- Precise, stable temperature control (±0.1°C when integrated with advanced CDU controls)
- Lower water and power consumption (ESG & NABERS support)
- Scalable for high-density and AI/HPC racks (100kW+)
- Leak detection, predictive maintenance, remote monitoring
