Plant-room telemetry
Temperature, pressure, flow, pump status, valve positions and equipment runtime in one operational view.
Enterprise IoT for mechanical plant
Make every plant room measurable, controllable and easier to run.
Controlled Flow brings practical plant-room engineering into the IoT era, connecting heating, hydronic, biomass, HVAC and district-energy assets to live telemetry, secure remote access, customer white-listing and optimisation.

From mechanical expertise to IoT outcomes
Enterprise IoT designed for the plant rooms that keep buildings running.
New sensors are useful only when the deployment understands pumps, boilers, valves, heat exchangers, control philosophy, secure access, customer firewalls and maintenance realities. Controlled Flow IoT is built around that site knowledge.
Energy optimisation
Trend heat demand, detect short cycling, tune setpoints and reduce operational cost without losing comfort.
Early fault detection
Spot abnormal deltas, sensor drift, low pressure, pump issues and boiler lockouts before they become callouts.
Compliance evidence
Generate service records, operating history and biomass maintenance evidence with less manual chasing.
Remote service access
Give engineers controlled access to site gateways, controllers and plant data without exposing equipment directly.
Static IP white-listing
Use dedicated egress ranges so enterprise customers can allow-list Controlled Flow access in their firewalls.
Controlled Flow IoT platform
A clear control surface for complex building energy systems.
Monitor commercial and domestic estates from a single secure portal. Give managers the overview they need and engineers the detail they expect: live points, event history, thresholds, asset context and trend data.
- Wireless or wired sensing for retrofit and new-build plant rooms.
- BMS, Modbus, M-Bus and gateway integrations where existing controls already exist.
- Role-based dashboards for owners, facilities teams, contractors and service engineers.
- Whitelist-ready static egress IPs for enterprise firewall and vendor-access workflows.
- Tenant-isolated access policies, audit trails and actionable alerts.

Secure remote access network
Built for enterprise sites that need fixed IPs, clean separation and auditable access.
Many customers cannot allow anonymous cloud traffic into operational systems. Controlled Flow IoT can provide customer-specific access paths, static outbound IP ranges and isolated tenant policies so facilities teams can approve remote monitoring and service work with confidence.
Dedicated IPv4 egress pools
Assign stable source IP ranges for monitoring, API delivery and remote engineering sessions.
Customer firewall white-listing
Give enterprise IT teams a clear allow-list model instead of changing policies for unknown cloud traffic.
Tenant-isolated routing
Separate customers, sites and service environments so one estate is not sharing access paths with another.
Controlled engineer access
Use role-based permissions, session logging and gateway-level access rather than direct public exposure.
Customer sites
Plant gateways, BMS points, controllers, sensors
Controlled Flow access fabric
Static egress, tenant policy, monitoring, audit
Approved stakeholders
Facilities teams, service engineers, enterprise IT
Deployment model
Start with the assets that matter, then scale across the estate.
Controlled Flow can survey, specify, install and commission the sensor layer, then help facilities teams operationalise the data with thresholds, dashboards, fixed-IP access policies and planned maintenance workflows.
Survey
Map plant topology, failure modes, controls, metering and access constraints.
Connect
Fit sensors and gateways, integrate controllers, assign tenant routing and validate data quality.
Operate
Configure dashboards, alert rules, firewall white-listing, service actions and management reports.
Optimise
Use trend evidence to tune systems, reduce waste and plan preventative maintenance.

Commercial sites where downtime, waste and poor visibility cost money.
