In modern data centers, reliable, scalable and energy-efficient cooling is crucial for optimal performance and uptime.
As computing power and rack densities continue to increase, data center cooling concepts are undergoing a fundamental shift. Air cooling is reaching its physical and economic limits – liquid cooling is becoming the standard for high-performance and future-ready data centers.
Across the entire operating temperature range, water has a thermal conductivity that is more than 20 times higher than air. This makes water vastly more effective at absorbing and transporting heat away from IT components. The result is higher cooling efficiency, reduced energy consumption and the ability to support significantly higher rack densities. Liquid cooling delivers significant efficiency gains for direct-to-chip thermal management, but those benefits depend entirely on water purity. In direct-to-chip cooling systems, critical microchannels are etched directly into the silicon of the processor. These hair-thin pathways are highly sensitive to contamination - any particulate that passes through or bypasses filtration can obstruct a microchannel, immediately degrading heat transfer performance. Proper high-efficiency filtration is essential to protect microchannels, maintain cooling efficiency, and ensure long-term system reliability.
For reliable and efficient data center cooling, trust 75 years of mission-critical filtration experience and proven performance. Our solutions ensure maximum uptime by delivering clean, stable cooling fluids essential for heat exchange and system protection.
With + 40 years of expertise in automatic coolant filtration (KSS applications), we provide advanced, self-cleaning technology designed to protect mission-critical cooling systems throughout the entire cooling circuit – from water intake to the CDU. Our solutions are backed by continuous R&D, cutting-edge engineering, and a clear commitment to setting industry standards.
Data centers using traditional air cooling exhibit a significantly higher Power Usage Effectiveness (PUE) compared to facilities utilizing water-based direct-to-chip or immersion cooling.
Lower PUE means:
- Reduced energy consumption
- Lower operating costs
- Improved sustainability metrics
Yet even minor contamination in cooling water can reduce heat transfer efficiency, increase pumping energy and compromise the PUE gains. Reliable filtration is therefore a critical enabler of low PUE liquid cooling concepts.
From municipal supply to reclaimed or process water, BOLLFILTER delivers tailored filtration solutions that guarantee maximum reliability and performance – at a competitive price. In mission-critical environments like hyperscale or HPC facilities, a single unplanned downtime event can cost 10 times more than the filter itself, making dependable filtration not just a smart choice, but a necessity.
Our systems are engineered to:
Protect cooling operations
Minimize maintenance and operational risk
Optimize total cost of ownership
Keep your cooling infrastructure on track for the future with self-cleaning filters that offer infinite scalability or up to 10x capacity expansion, ensuring your filtration system grows seamlessly alongside your data center
Our solutions combine reliability, innovation and scalability – because in mission-critical environments, performance isn’t optional. It’s essential.
With over 75 years of experience, Boll & Kirch develops customized and sustainable filtration systems for demanding cooling water systems.

- Cost-effectiveness of your data center
- Absolute operational safety in mission-critical environments
- Maximum operational reliability: Our filters reliably remove even the finest contaminants from the cooling water – for maximum protection of sensitive system components.
- Continuous operation: Self-cleaning automatic filters and maintenance-friendly double filters enable filtration without interruption – even during maintenance or cleaning work.
- Flexible solutions: Individually customizable filter elements from coarse to fine – perfectly tailored to the individual requirements of your cooling water systems.
- Durability: Manufactured from corrosion-resistant materials, such as stainless steel, for extreme robustness, high availability, and a long service life – even under continuous load.
Contaminants such as sand, sediments, algae, biofilm or rust particles can damage heat exchangers, pipes and valves. Reliable cooling water filtration protects components, ensures energy efficiency and prevents downtime.
BOLLFILTER ensures continuous filtration, high operational reliability, extended service life and efficient removal of the finest particles. Our systems are low-maintenance, corrosion-resistant and, depending on the filter type, self-cleaning or particularly easy to clean - ideal for 24/7 cooling operation.
Self-cleaning automatic filters are recommended for open or heavily polluted water sources. In closed loop systems, double filters offer maximum safety and easy maintenance without system downtime.
Yes. Our filters reliably handle cooling water from wells, rivers, lakes or seawater. Thanks to various filter finenesses, every water quality can be treated in an optimal way.
Automatic filters are self-cleaning and therefore require minimal maintenance. Double filters are particularly easy and quick to maintain thanks to their design, without interrupting the filtration process. The actual maintenance and cleaning intervals depend heavily on the prevailing operating conditions, such as water quality, flow rate, operating time and filter type.
Clean cooling water reduces pressure losses, optimizes heat transfer and prevents fouling. This lowers the energy consumption of pumps and cooling units - an important factor for overall efficiency and sustainability.
Yes, BOLLFILTER solutions are modular in design and can be easily integrated into new and existing cooling system, regardless of size or complexity.
