Background
A prominent UK hotel group, managing multiple properties nationwide, adopted a forward-thinking approach to water hygiene by implementing secondary disinfection in place of high-temperature control methods. This shift was driven by a desire to reduce energy usage and environmental impact while maintaining safe, compliant water systems across all sites.
The Challenge
Rather than waiting for water quality issues to emerge, the group acted pre-emptively, seeking a safer, long-term alternative to chlorine dioxide systems. Their goals were clear: eliminate the handling and storage of hazardous chemicals, lower utility bills, and minimise scalding risks for guests, especially in sites with ageing infrastructure and limited plant room space.
Our Solutions
Genox emerged as the preferred solution across several locations. Its ability to generate a potent disinfectant on-site using just salt, water, and electricity offered a safer, more sustainable option. The system integrates seamlessly into existing infrastructure without the need for major disruption.
Key Benefits of Genox:
- No hazardous chemical transport or storage required
- Generates hypochlorous acid (HOCl) via electrolysis
- Enables safe reduction in hot water temperatures to save energy
- Low running costs compared to chlorine dioxide systems
- Compact and easy to install in plant-constrained environments
Lessons learned
Initial deployments provided valuable insights:
- In hard water areas, site-specific water softening must be accounted for at the proposal stage
- Fluctuating water temperatures require careful calibration to maintain consistent performance
These learnings are now shaping best practices for future installations, ensuring optimised performance and reliability.
Outcome & Impact
- Multiple installations are now operating successfully
- Lower operational risks and significant cost savings achieved
- Customer teams report improved satisfaction and confidence in system reliability
- Genox is now part of the group’s wider environmental and compliance strategy
