Ecolab’s CoolIT buyout spurs Calgary expansion to meet AI data-centre cooling demand
Ecolab’s acquisition of CoolIT accelerates Calgary expansion as AI-driven data centre demand for liquid cooling drives hiring, growth and global contracts.
Calgary’s CoolIT Systems has begun a period of rapid expansion after being acquired by Ecolab in early 2026, as demand for liquid cooling from AI-focused data centres pushes the company to scale manufacturing and staff. The acquisition, valued at roughly US$4.75 billion (about CA$6.6 billion), has prompted the St. Paul, Minn.-based buyer to invest in production, engineering and research in the city where CoolIT was founded. Company and local officials say the move aims to keep critical cooling supply lines open as hyperscalers and cloud providers accelerate deployments of high-performance computing infrastructure.
Ecolab completes multibillion-dollar acquisition of CoolIT
Ecolab finalized the purchase of CoolIT earlier in 2026, folding the Calgary-based liquid-cooling specialist into its global high-tech division. The transaction gives Ecolab a precision-manufacturing and technology capability it has sought to complement its water, sanitation and hygiene operations.
Executives have described the deal as strategic rather than purely financial, citing CoolIT’s engineered coldplates and coolant distribution units as technologies that integrate with Ecolab’s expertise in fluid systems. Company leadership says the acquisition fills a manufacturing gap and positions Ecolab to supply large-scale data-centre projects.
Calgary manufacturing and hiring surge
Since the acquisition, CoolIT’s Calgary headcount has climbed markedly, growing from roughly 650 employees to nearly 900 as the company ramps production. Dozens of job listings remain open and executives indicate further hiring is planned to support increased manufacturing and R&D capacity.
Ecolab leaders have committed to expanding design, engineering and research activity in Calgary, describing the city as a permanent hub for their data-centre operations. Local tech organizations see the hiring binge as a signal that Calgary can nurture companies that scale globally.
Liquid cooling technology built for AI workloads
CoolIT’s products — including precision coldplates that sit directly on processors and larger coolant distribution units — are designed to dissipate the intense heat generated by modern AI chips. Engineers argue liquid cooling is increasingly essential as processors grow more powerful and more densely packed, creating thermal challenges air systems cannot easily address.
On factory floors, technicians assemble intricate manifolds and test cooling channels to exacting tolerances, reflecting the precision manufacturing Ecolab sought. Production leaders say these components are integral to the reliability and performance of next-generation data centres.
Work with hyperscalers and local projects under way
CoolIT reports active collaboration with hyperscale cloud providers from the design phase through deployment to make sure cooling systems are available when data centres come online. The company says it is engaged with multiple projects in Alberta and across Canada as hyperscalers and AI firms announce regional investments.
Recent public plans by major tech firms to build data centres in Alberta have created local opportunities, and CoolIT executives say they are working on several initiatives in the province. The company also maintains satellite offices in regions such as the U.S. Bay Area and Houston to serve customers closer to major cloud and enterprise hubs.
Ecolab links water systems expertise to precision cooling
Ecolab’s core business in water treatment and fluid management provides a logical bridge to liquid-cooling systems used in data centres, company officials explain. They describe CoolIT’s manufacturing backbone as the missing piece to bring fluid systems and precision electronics cooling under one corporate roof.
Executives say combining Ecolab’s global reach with CoolIT’s specialized technology accelerates product availability and reliability for large-scale customers. That integration has led to promises of bolstered manufacturing footprints and continued investment in Calgary facilities.
Market outlook and risk amid AI investment surge
Industry officials acknowledge the rapid growth in demand for AI compute creates both opportunity and risk, with some analysts warning of a speculative investment cycle. Companies building infrastructure for AI could face slower demand if corporate forecasts prove overly optimistic, which would affect suppliers across the supply chain.
Still, major chipmakers have signaled continued strong growth in compute demand, supporting the case for expanded cooling capacity. CoolIT and Ecolab leadership say they will continue to monitor market dynamics while preparing to meet projected customer requirements.
Calgary’s tech community welcomes the investment and the hiring that accompanies it, viewing CoolIT’s expansion as a potential catalyst for more locally based, globally minded companies. The infusion of manufacturing jobs and engineering work offers a pathway to diversify an economy long centered on energy, and local leaders hope the cycle of growth will generate further entrepreneurial activity in the region.
