What is the ATI SiteBox?

The ATI SiteBox provides a smart, connected approach to monitoring closed water systems. Using advanced sensor technology and remote telemetry, it offers continuous insight into key water quality parameters, allowing early detection of corrosion, leaks, or microbiological fouling before they become costly issues.

Quick to install and simple to operate, the ATI SiteBox delivers real-time data, automated alerts, and a clear picture of system health — all accessible remotely through an intuitive web dashboard.

Why choose Complii?

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for the ATI sitebox.

Smarter monitoring for modern systems

Complii’s ATI SiteBox enhances traditional monitoring practices by analysing water quality continuously rather than through periodic manual sampling. This enables Responsible Persons to detect issues early, act proactively, and demonstrate compliance with the latest BSRIA BG29 and BG50 guidance.

Versatile applications

The ATI SiteBox can be deployed across multiple use cases — from temporary installations following pre-commission cleaning to permanent integration for ongoing performance monitoring. It’s ideal for system health checks, troubleshooting, and verifying remediation work, offering complete visibility throughout a building’s lifecycle.

Reducing risk and cost

Continuous data collection helps prevent microbiological fouling, corrosion, and scaling — the leading causes of system failure and inefficiency. By monitoring trends in real time, the ATI SiteBox enables early intervention, reducing maintenance costs, downtime, and the risk of major asset damage.

Compact, portable, and powerful

With a small footprint and rugged design, the ATI SiteBox is built for use across maintenance environments and construction sites. It can be powered via mains, battery, or low-voltage DC supply, making it a flexible option where traditional instrumentation cannot be installed.

Real-time insights and remote data collection

Through its integrated telemetry system, the ATI SiteBox records and transmits live data over secure 2G, 3G, NB-IoT, and LTE networks. A cloud-based dashboard displays current conditions, historical data, and automated alarms, ensuring operators can monitor performance anywhere, anytime, via laptop or smartphone.

Supporting compliance and performance

By aligning with BSRIA and BS8552 recommendations, the ATI SiteBox supports accurate corrosion monitoring and ongoing system health assessment. Its data-driven insight helps dutyholders maintain inhibitor levels, detect oxygen ingress, and optimise water treatment strategies to maximise plant life and performance.

Your questions answered.

  • It continuously tracks parameters such as temperature, pressure, pH, conductivity, dissolved oxygen, turbidity, and flow, helping identify conditions that could lead to corrosion, scaling, or microbial growth.

  • By providing instant visibility of water conditions, the ATI SiteBox flags abnormal readings before they escalate into system failures, ensuring safe, efficient, and compliant operation.

  • Yes. It can be installed temporarily for system commissioning, investigations, or troubleshooting, or permanently for continuous health monitoring of closed heating and cooling systems.

  • All data is logged and transmitted securely to a cloud-based platform. Users can visualise results in dashboards, export reports, and receive automated alerts via SMS or email.

  • Complii combines leading water monitoring technology with expert engineering support. We ensure every installation delivers accurate data, reliable performance, and measurable improvements in system health and compliance.
