Citritek

Citritek is a data-driven water safety consultancy that helps healthcare estates teams understand, balance, and de-risk their water systems. Using proprietary wireless monitoring technology, rapid laboratory testing, and deep analytics, we give estates managers and Authorising Engineers the evidence they need to target microbiological hazards — principally Legionella and Pseudomonas — with precision rather than guesswork.

Our approach is built around continuous data capture from the points that matter: sentinel outlets, primary, subordinate and tertiary loops, calorifiers and plate heat exchangers, and remote areas. Low-power LoRaWAN® sensor networks feed live temperature, flow, and environmental data into our secure platform, where AI-powered analytics surface trends, flag exceptions, and generate audit-ready reports — all designed around HTM 04-01 workflows in hospitals, mental health trusts, and community care estates.

What this means for your estate:

• Targeted risk control: Continuous monitoring and trend analysis let estates teams see where microbiological risk is actually building, so flushing regimes and remedial actions go where they are needed — not everywhere at once.
• Demonstrable compliance: Reporting aligned to HTM 04-01, with configurable reports for reviews that give Authorising Engineers clear evidence of risk control.
• Operational efficiency: Data-led maintenance reduces unnecessary access to clinical areas, drastically reduces manual checks, and focuses resource on genuine priorities.
• Hard-to-reach coverage: LoRaWAN® delivers building-penetrating telemetry with multi-year battery life, capturing data from spaces that would otherwise go unmonitored.
• Beyond water: Cold-chain monitoring for vaccine storage integrity; indoor air quality monitoring (CO₂, PM₂.₅, VOCs, RH, temperature) to support ventilation and comfort strategies.

Citritek is a UK company serving the NHS, independent healthcare providers, and the private sector. We offer a fully managed service — from survey and design through installation, commissioning, and ongoing compliance reporting — and can integrate with existing BMS/CAFM platforms where required.
