Precise hydronic control for data centre cooling
Data centre cooling systems need to remove heat reliably as IT loads and operating conditions change. BELPARTS supplies valves, actuators, sensors and smart flow-control solutions for chilled-water cooling units, secondary loops and distribution branches. Controlled water flow and accessible operating data help technical teams commission, monitor and adjust the hydronic system.
Cooling performance starts with controlled water flow
Cooling capacity depends on delivering the required flow at the right temperature and pressure conditions. Too little flow can limit heat removal; uncontrolled excess flow can reduce system efficiency and make adjacent circuits harder to regulate. Accurate control and relevant measurement help designers, commissioning teams and operators understand how the hydronic system is performing.
BELPARTS works with consultants, contractors, system integrators and equipment manufacturers to match hydronic components to the cooling architecture. Selection considers how each component operates within the wider system during normal service, maintenance and faults.
Key applications in data-center cooling
Coil-flow control for chilled-water cooling units
Computer room air handlers (CRAHs) and other chilled-water cooling units need controlled water flow as thermal loads and system differential pressure change. Electronic pressure-independent control can combine modulating flow regulation, dynamic balancing and operating feedback, depending on the selected product.
For equipment manufacturers, a coordinated valve and control arrangement supports consistent hydraulic performance across a cooling-unit range. Integration covers the control sequence, communication interface, response to loss of power or communication, and access for commissioning and maintenance.

Secondary cooling-loop and branch control
Secondary loops and distribution branches need to supply the required flow to active cooling equipment as demand changes. dynamx™ smart flow control valves support flow regulation and dynamic balancing, with measurement and wired communication functions according to the selected model. Each selection must match the circuit’s medium, flow range and operating conditions.
The solution should be assessed as part of the complete system design, including pump strategy, redundancy concept, minimum-flow requirements and the operating states used during normal service, maintenance and failure conditions.
Flow, temperature and ΔT performance monitoring
Flow and temperature data help commissioning teams and operators assess cooling delivery and the temperature difference (ΔT) between supply and return. Where supported by the selected product and building management system (BMS), wired communication makes these values available for functional testing, alarms, trend analysis and fault investigation.
Measurement range, accuracy, sensor configuration and communication protocol must match the intended monitoring task. Product documentation provides the basis for checking these requirements during design and integration.
Support for engineering teams and operators
Critical facilities and engineering teams
Stable coil and branch flow, defined behaviour during power or communication loss, and accessible operating data support commissioning and fault investigation. These features help engineering teams assess hydronic performance during normal operation, maintenance and changes in cooling demand.
Data-center operators and colocation providers
Controlled water distribution and useful operating data help operators identify excess flow, investigate temperature differences and assess opportunities to improve cooling efficiency. Energy performance depends on the complete cooling architecture, control strategy and operating conditions.
Match components to the cooling system
Component selection takes account of:
- cooling medium and glycol concentration
- operating and ambient temperature ranges
- design flow, differential pressure and pressure rating
- nominal size and connection standard
- control signal, communication protocol and project cybersecurity requirements
- required behaviour during loss of power or communication
- applicable regional conformity and certification requirements
- installation, commissioning and maintenance access
Depending on these requirements, the solution may include dynamx™ smart flow control valves, conventional control valves and actuators, and temperature or pressure sensors. Available functions, interfaces and certifications depend on the selected product and configuration.
Engineering and OEM collaboration
Data centre projects require coordination between the valve supplier, cooling-equipment manufacturer, controls provider and engineering team. BELPARTS supports application review and product integration, helping teams clarify hydraulic requirements, control interfaces and commissioning needs.
