Filtration for Historic Buildings and Sites

Historic buildings are an integral part of our cultural heritage, representing the architectural marvels of the past. However, these magnificent structures often face numerous challenges in maintaining their water quality. The accumulation of sediments, rust, and other contaminants in the plumbing systems of historic buildings can lead to reduced water flow, corrosion, and even health hazards. To combat these issues and ensure the sustainability and longevity of these architectural gems, side stream filtration has emerged as a promising solution. 

Challenges faced by historic buildings in maintaining water quality 


Historic buildings, by their very nature, often have outdated plumbing systems that are more susceptible to water quality issues. Over time, sediment, rust, and other contaminants accumulate within the pipes, compromising water flow and quality. These contaminants not only affect the aesthetics and taste of the water but also pose health risks to occupants. Furthermore, the preservation of historic buildings requires careful attention to their original materials, and the corrosive nature of these contaminants can accelerate the deterioration of these materials. As a result, maintaining water quality in historic buildings becomes a complex challenge that requires innovative solutions.

VEXO’s Solutions to Maintain and Restore Water Quality


At VEXO, we offer a range of solutions designed to maintain and restore water quality in HVAC systems. Our holistic approach to building management and commercial water treatment solutions safeguards system reliability, ensuring optimal service levels and avoiding any heating-related breakdowns. 

The X-POT is a commercial side stream filter that operates in side stream for easy maintenance without the need to shut down the system. The X-POT captures lifted biofilm, sludge corrosion, and scale debris, ensuring the water quality in the HVAC hydronic system is as clean as possible. This not only decreases overhead expenditure on energy bills but also reduces the risk of unexpected breakdowns and repair costs, conserving the lifespan of HVAC equipment for years to come.

In addition to filtration, we also offer a suite of commercial water treatment products and additives that offer superior protection for aged but also new hydronic HVAC heating, chilled, and condenser systems. These additives, including commercial descaler and commercial inhibitor, lift biofilm and sludge, dissolve scale, and passivate corrosion, increasing the efficiency of the system.  

Case studies of successful side stream filtration and additives implementation in historic buildings 

These case studies highlight the transformative power of side stream filtration in historic buildings. By addressing water quality issues, these systems contribute to the preservation, sustainability, and longevity of these architectural treasures.

The future of side stream filtration in enhancing sustainability and longevity of historic buildings 


Side stream filtration has emerged as a valuable tool in the preservation and sustainability of historic buildings. By addressing water quality challenges, these filtration systems enhance the overall experience for occupants and visitors while protecting the building’s materials and infrastructure. The case studies of successful implementation demonstrate the positive impact side stream filtration can have on the longevity and legacy of historic buildings. 

As we look to the future, the continued development and refinement of side stream filtration technologies hold great promise. Advancements in filtration techniques, such as the integration of more efficient and sustainable materials, will further improve the effectiveness and environmental impact of these systems. With the increasing focus on sustainability and the preservation of cultural heritage, X-POT will undoubtedly play a vital role in ensuring the continued enjoyment and appreciation of historic buildings for generations to come.
