Vertiv launches global ecosystem to advance end-to-end thermal and fluid management for ai-scale infrastructure.

Vertiv launches global ecosystem to advance end-to-end thermal and fluid management for ai-scale infrastructure. October 27, 2026 Expanded Dow collaboration and new Solenis partnership combine thermal infrastructure, fluid health, monitoring and lifecycle services for AI-scale liquid cooling. COLUMBUS, Ohio - Vertiv (NYSE: VRT), a global leader in critical digital infrastructure, today announced a global ecosystem offering that brings together an expanded collaboration with Dow, a materials science company and provider of advanced coolant technologies, and a new partnership with Solenis, a provider of specialty chemicals and water treatment solutions, to help operators manage and optimize liquid cooling infrastructure as a single, integrated thermal system. The initiative integrates Vertiv's infrastructure, monitoring and global service capabilities with fluid chemistry, coolant and water treatment expertise. As AI workloads drive unprecedented computing densities, liquid cooling is becoming a system-management challenge, not simply a component challenge. Reliability and performance now depend on the entire thermal chain, from heat rejection and chilled water infrastructure through facility and technology cooling loops, coolant distribution, fluid chemistry, filtration, leak detection, monitoring and controls. "AI is changing liquid cooling from an equipment decision into a system-management imperative," said Ron Bednar, Senior Vice President of Global and Americas Services at Vertiv. "Operators need to manage thermal infrastructure, fluid health, monitoring and lifecycle service as one interconnected discipline. We believe that managing these complex interdependencies and fluid chemistry together will help operators improve system efficiency and uptime, reduce risk and extend equipment life." Vertiv expanded its collaboration with Dow through the Dow Coolant Care Network and initiated a new partnership with Solenis to support end-to-end fluid management and thermal infrastructure services. Integrated with Vertiv's monitoring and lifecycle capabilities, these offerings help customers maintain fluid quality, address system issues and optimize liquid cooling performance throughout the system lifecycle. Through this ecosystem, Vertiv, Dow, and Solenis will help customers: * Design for system compatibility: Optimize cooling systems for maintainability and operational efficiency while ensuring compatibility across fluids, materials and infrastructure components. * Establish clean, stable systems: Use engineered flushing, precision filling, commissioning and filtration practices to protect cooling infrastructure and maintain system cleanliness. * Monitor the thermal system: Gain unified visibility into thermal infrastructure through the Vertiv(TM) Next Predict monitoring and analytics platform. * Detect and address issues early: Use continuous monitoring and integrated leak detection technologies to support early operational response and improve resilience. * Continuously optimize performance: Apply advanced analytics, software and data-driven insights to improve efficiency and water utilization. * Manage fluid health and total cost: Proactively manage fluid chemistry across technical and facility water systems based on system operating conditions to support equipment life and reduce total cost of ownership. Vertiv integrates thermal infrastructure, fluid health, monitoring and lifecycle services into a unified operating model for high-density liquid-cooled infrastructure. About Vertiv Holdings Co. Vertiv Holdings Co. (NYSE: VRT) brings together hardware, software, analytics and ongoing services to enable its customers' vital applications to run continuously, perform optimally and grow with their business needs.

Solenis relocates Pulp Center of Excellence to Brazil to accelerate innovation for the global pulp industry.

Solenis relocates Pulp Center of Excellence to Brazil to accelerate innovation for the global pulp industry. 6 October 2026 15:58 Solenis, a leading global provider of water treatment, process and hygiene solutions, has relocated its Pulp Center of Excellence from the U.S. to a new facility in Paulínia, Brazil. The move expands the company's global research and development capabilities and positions innovation closer to the world's fastest-growing pulp region. Located alongside Solenis' existing Paulínia Technology Center, the new 500-square-meter facility is dedicated to developing global solutions for the pulp industry. It brings together scientists, application expertise, process knowledge and advanced testing capabilities to help customers address complex operational, efficiency and sustainability challenges. The center is staffed by a dedicated team of scientists and technicians with deep expertise in pulp applications, process chemistry and customer-focused innovation. "By placing our global pulp innovation capabilities in Brazil, we are moving closer to our customers and to one of the most dynamic pulp regions in the world," said Christoph Adami, Vice President, Innovation. "This center strengthens our ability to collaborate directly with producers, accelerate innovation cycles and develop next-generation technologies that help pulp manufacturers worldwide improve productivity, cost position and sustainability." Latin America has become a global hotspot for pulp production, with regional capacity increasing significantly over the past decade and additional growth expected. Brazil remains a key destination for industry investment, with Mato Grosso do Sul accounting for a large share of announced pulp projects. Solenis' Pulp Center of Excellence is strategically located in the Campinas/Paulínia technology hub, enabling faster responses to customer needs and closer collaboration with key regional producers. "Latin America plays a pivotal role in the evolution of the global pulp industry and Brazil remains one of the sector's most important investment destinations. The new Pulp Center of Excellence strengthens our ability to work side by side with customers, respond quickly to emerging needs and bring the best of Solenis' global expertise to support their growth and operational success," said José Aguirre, Vice President and General Manager, LATAM. The center supports full-process coverage, from wood handling through cooking, brownstock washing, bleaching, recausticizing and refining. These capabilities allow Solenis teams to simulate different stages of pulp manufacturing, evaluate treatment programmes and develop solutions across the entire pulp mill. Current development areas include a talc-free pitch control platform, pitch monitoring equipment co-developed with industry partners, a first-of-its-kind cooking additive designed to improve cooking yield, and a silicone-free defoamer family already recognised in the Brazilian market. Together, these technologies reflect Solenis' focus on helping pulp producers optimise performance, reduce operational constraints and support more sustainable production. Solenis continues to invest in R&D capabilities to support customers globally and reinforce its commitment to the pulp and paper industry. The center complements customer expertise and production knowledge with Solenis' broad portfolio of chemistry, monitoring and process solutions, creating a collaborative environment for innovation and long-term value creation. The company maintains 16 R&D centers globally, strategically located to focus on critical specialties, with some operating as Centers of Excellence. In addition, the company operates 11 Customer Application Laboratories (CALs) to help customers solve complex, real-world chemistry challenges.
