Wafr Technologies, a Singapore-backed cooling startup, raised $100 million to develop water-efficient chilling systems for AI data centers. The company is now seeking an additional $200 million to scale operations.
As AI compute demands explode, cooling costs are becoming a bottleneck. Data centers consume massive electricity for both processing and refrigeration. Wafr’s water-based approach cuts cooling energy usage significantly, making it attractive to hyperscalers operating on razor-thin margins.
The Cooling Crisis
Google reported that electricity consumption spiked 37 percent year-over-year in its latest environmental report. Water use climbed 34 percent. These numbers track directly with AI infrastructure buildout.
Cooling represents 20–40 percent of data center operating costs depending on geography and ambient temperature. Novel cooling tech is becoming as strategic as chip design.
Investment Signals Strategy
Wafr’s funding reflects investor confidence that cooling infrastructure will be a long-term business. OpenAI, Anthropic, Meta, and Google are all racing to add compute capacity. Each new AI model generation burns more electricity.
Water-efficient cooling isn’t sexy, but it’s foundational to scaling AI infrastructure cost-effectively.
