Hydrosphere Innovations is a leading UK engineering specialist in closed-loop HVAC water treatment.
As the developer and patent holder of the Hydrosphere® Process (Closed-Loop Pre-Treatment Cleaning, CPC), Hydrosphere has pioneered an effluent-free cleaning method that removes system contaminants, eliminates corrosion and protects long-term network performance while reducing programme time, water use and environmental impact.
Hydrosphere’s equipment – much of it patented – is engineered to support projects of any scale, from individual building systems to city-wide heating and cooling networks and data centres, delivering better performance, improved water quality and extended asset life. We have all that is required for small to substantial networks up to and including 600mmØ pipework.
With more than 40 years of expertise, Hydrosphere has supported leading providers including Vital Energi, ThermaMech, Pinnacle Power, Energetik, E.ON, Veolia and Hemiko on district schemes. Our technology has also been deployed on landmark developments including The Shard, Francis Crick Institute, Greenwich Energy Centre, Royal Albert Docks, Heathrow, Canary Wharf, Bank of America, and Nine Elms.
Hydrosphere also provides expert technical consultancy and on-site engineering support helping clients – be they water treatment firms, M&E companies, asset owners, or energy suppliers – to deliver resilient, high-performing systems across the UK and internationally.
Hydrosphere is helping industry move towards a smarter, more sustainable future for water treatment and system management.
