As AI infrastructure evolves, filtration is becoming a critical enabler of cooling system performance, reliability and sustainability. And Cleanova is right at the NEXUS of next-generation data center cooling performance.
The rapid growth of artificial intelligence, cloud computing, and high-performance data processing is reshaping the global data center landscape. Increasing rack densities and greater computing power are generating unprecedented heat loads, driving the adoption of increasingly sophisticated cooling technologies.
While much attention focuses on servers, GPUs and cooling equipment, one critical factor often receives less consideration: filtration.
Whether a facility relies on traditional air-cooled architecture, advanced liquid cooling systems or a combination of both, effective filtration plays an essential role in protecting infrastructure, maintaining efficiency, and supporting reliable operations.
Cleanova supports data center operators across the full spectrum, providing air and liquid solutions tailored to each system. This is where Cleanova.NEXUS™ comes in.
Cleanova.NEXUS™ is our approach to mission-critical technologies and integrated filtration solutions designed for the industries shaping tomorrow’s world.
Rather than viewing air filtration, liquid filtration, and solids separation as separate technologies, Cleanova connects them into a coordinated filtration strategy designed to support system-wide performance across critical infrastructure.
By bringing together expertise from across Cleanova’s portfolio of technologies and trusted filtration brands, Cleanova helps customers address contamination challenges at every stage of their process—from air intake protection and cooling loop cleanliness to wastewater treatment.
For data center operators, this integrated approach provides a single filtration partner capable of supporting the entire cooling ecosystem.
The Growing Challenge of Data Centre Cooling
Modern data centers must maintain precise operating conditions while supporting continuously increasing computational demands.
As processing power increases, so do thermal loads. Higher temperatures can reduce equipment performance, accelerate component degradation, and increase the risk of unplanned downtime.
To address these challenges, operators are increasingly deploying a combination of:
- Air-cooled systems
- Chilled water systems
- Cooling towers
- Direct-to-chip liquid cooling
- Hybrid cooling architectures
Each of these technologies introduces unique contamination risks that can impact cooling performance and operational efficiency.
A successful cooling strategy therefore requires more than heat management alone; it requires effective contamination control throughout the system.
Protecting Air-Cooled Infrastructure
Air remains a primary cooling medium in many data centers around the world.
However, airborne contaminants can significantly affect system performance and reliability. Common challenges include:
- Construction dust
- Environmental debris
- Industrial pollutants
- Pollen and organic particulates
If left unmanaged, these contaminants can accumulate on coils, restrict airflow, and increase the energy required to move air through cooling systems.
The result can be increased operating costs and reduced Power Usage Effectiveness (PUE).
Cleanova’s air filtration technologies are designed to remove contaminants while maintaining optimized pressure drop performance, helping operators protect sensitive equipment while minimizing unnecessary fan energy consumption.
Supporting the Transition to Liquid Cooling
As AI workloads continue to increase power densities, liquid cooling technologies are becoming increasingly important.
Liquid cooling systems offer significant thermal management advantages but introduce a different set of contamination risks, including:
- Corrosion by-products
- Installation debris
- Pipe scale
- Suspended solids
- Biological contamination
Without proper filtration and water management practices, these contaminants can contribute to fouling, reduced heat transfer efficiency, and premature wear of critical components such as pumps, heat exchangers, and cooling distribution units.
Cleanova supports liquid cooling applications through a comprehensive range of filtration solutions including strainers, liquid filter bags, cartridge filters and solids management technologies designed to maintain fluid cleanliness and system reliability.
A Filtration Strategy Across the Entire Cooling Ecosystem
One of the greatest challenges facing data center operators is that contamination issues rarely occur in isolation.
Air handling units (AHUs), computer room air conditioning (CRAC), computer room air handling units (CRAH), coolant distribution units (CDU), cooling towers, chilled water loops, treatment systems and wastewater streams are interconnected. Performance issues in one area can affect overall cooling efficiency and operational reliability.
Cleanova.NEXUS™ addresses this challenge through an integrated filtration approach that can encompass many solutions, as shown in the process flow below.
Air Filtration Solutions
Cleanova’s air filtration solutions help protect cooling equipment and critical electronic infrastructure from airborne contaminants. Installed within AHUs and CRAC/CRAH systems, multi-stage filtration helps maintain air quality and support reliable data center operation.
Liquid Filtration Solutions
Cleanova’s liquid filtration solutions are helping maintain fluid cleanliness and protecting server equipment, pumps, valves, heat exchangers, and cooling equipment.
Mechanical Separation
Removing solids and particulate contamination through engineered filtration solutions tailored to each system’s operating requirements, supporting cooling water loops, make-up water treatment, side-stream filtration, and CDU primary and secondary loop protection.
Solids Management
Supporting cooling tower blowdown treatment and wastewater management through dewatering technologies such as filter presses, helping reduce solids loading, improve water quality and support reuse or discharge requirements.
By connecting these technologies into a coordinated strategy, operators can achieve more consistent performance across the entire cooling infrastructure.
Supporting Sustainability and Operational Efficiency
Data center operators face increasing pressure to improve efficiency while reducing environmental impact.
Effective filtration supports sustainability objectives by improving heat transfer efficiency, extending equipment life, reducing water consumption through improved reuse strategies, and minimizing waste generated by premature component replacement.
- Specific sustainability benefits include:
- Reduced pump energy consumption
- Improved heat transfer efficiency
- Longer equipment service life
- Reduced maintenance interventions
- Water conservation opportunities
- Lower total cost of ownership
As cooling systems become more advanced, maintaining cleanliness throughout the process becomes increasingly important to achieving both operational and sustainability objectives.
Looking Ahead
The future of data centers will be defined by increasing computational power, higher thermal densities, and greater demands for efficiency and reliability.
As AI infrastructure accelerates the transition toward higher-density computing and advanced cooling architectures, contamination control is becoming a strategic operational discipline rather than a maintenance consideration. Organizations that address filtration holistically will be better positioned to improve reliability, reduce energy consumption, and support long-term sustainability goals.
Through Cleanova.NEXUS™, we are helping customers take this broader view of filtration, connecting air filtration, liquid filtration, and solids separation into integrated solutions that support critical infrastructure performance today and into the future.
Cleanova continues to expand its capabilities across mission-critical infrastructure. The recent addition of TES-Clean Air Systems and Airflotek further strengthens Cleanova’s expertise in advanced air filtration, HEPA/ULPA technologies, and controlled-environment solutions supporting AI-driven infrastructure, high-performance computing, and other contamination-sensitive applications. This broader capability reinforces the Cleanova approach of connecting filtration technologies across increasingly complex operating environments.
