Telehouse Canada Adopts Liquid Cooling for High-Density Data Centers

Telehouse Canada is setting a new benchmark for high-density computing in the Canadian market by implementing advanced direct liquid-to-chip cooling technology across its Toronto data center portfolio. This strategic move, the first of its kind within a Canadian interconnection hub, directly addresses the escalating power demands of artificial intelligence and high-performance computing workloads.

The innovative cooling solution facilitates rack densities reaching an impressive 120kW per rack. Unlike conventional air-cooling methods, direct liquid cooling leverages the superior thermal conductivity of liquids to extract heat directly from critical server components. This capability allows Telehouse to capture as much as 80 percent of the heat generated by these power-hungry systems at its source.

This direct heat removal significantly diminishes the operational burden on energy-intensive computer room air conditioners and internal server fans. Consequently, the overall energy footprint of the data centers is substantially reduced. Further enhancing efficiency, the system integrates a novel heat recovery mechanism, contributing to improved operational sustainability.

In a notable sustainability initiative, the captured heat is channeled into Enwave's established district energy network. Through a completely segregated process, this thermal energy is repurposed to warm Toronto's municipal drinking water supply, diverting waste heat from atmospheric release. This closed-loop integration not only bolsters Telehouse Canada's Power Usage Effectiveness (PUE) metrics but also aligns with the company's commitment to environmental stewardship.

The deployment spans Telehouse Canada's three key Toronto facilities: the 205,000 sq ft facility at 151 Front Street West (20MW capacity), the 82,000 sq ft site at 250 Front Street West (10MW capacity), and the 69,000 sq ft location at 905 King Street (10MW capacity). These facilities were acquired in 2024 from Allied Properties REIT, underscoring Telehouse's significant investment in the region's digital infrastructure.

This technological upgrade positions Telehouse Canada as a frontrunner in offering sustainable, high-capacity data center solutions within Canada. The ability to support extreme compute densities is becoming increasingly crucial as AI adoption accelerates, driving demand for specialized infrastructure capable of managing the associated thermal challenges. The company's proactive adoption of direct liquid cooling anticipates future market needs and reinforces its competitive edge in the digital infrastructure sector.
