AirWater Systems, Measured & Managed
Heating, cooling and domestic water all live or die by flow, pressure and temperature. We control the pumps and plant that move water around your building, prove what’s actually flowing with non-invasive measurement, and keep the records your compliance regime depends on — all without shutting anything down in critical "always-on" environments.
Ultrasonic Flow Metering
Highly accurate, clamp-on ultrasonic sensors (Katronic) that read hot and chilled water systems from outside the pipe.
Zero-Downtime Diagnostics
Balance HVAC water systems and track thermal loads in hospitals, data centers and airports without shutting off supply.
Leak & Consumption Baselines
Water-meter baselines with real-time alerts on pressure drops or abnormal consumption spikes.
The full water-side offering
Hydronic Balancing & Optimisation
Unbalanced LTHW and chilled water circuits waste pump energy and starve the far ends of buildings. We measure real flows, then fix the cause through the BMS — valves, pumps and setpoints tuned as one system.
Pump & Pressurisation Control
Inverter pump control with duty/standby/assist changeover, pressure-set and booster-set alarms, break tanks and pressurisation units under continuous BMS watch — failures flagged before the plant room floods or the heating stops.
Water Temperature Compliance
Automated calorifier, flow/return and sentinel outlet temperature monitoring that feeds your legionella (L8/HSG274) control regime — continuous logged records instead of clipboard rounds.
Water Metering & Leak Alarms
AMR water sub-metering with baseline tracking and out-of-hours flow alerts — the 3am leak shows up in the morning report, not the quarterly bill.
Where hot water meets duty of care.
Hospitals, care settings, hotels, schools and housing all carry a legal duty to manage water temperature. Automated monitoring turns that duty from a weekly clipboard round into a continuous, evidenced record — and flags the failures between visits.
