Cooling generation
Dunham-Bush air- and water-cooled chillers, including the magnetic-bearing range in the company profile. Selection follows duty, operating temperatures and site conditions.
Data-centre cooling
From the cooling plant
to the data hall.
Equipment selection, technical documentation and support for data-centre cooling generation, room-level heat removal and supporting infrastructure.

Application architecture
Different layers. A coordinated selection.
Distribution & hydronic control
Heat exchangers, PICV valves and kits, BTU meters, balancing, piping and insulation form part of the supporting portfolio.
Room-level heat removal
Precision cooling, in-row units and CRAH fan walls are air-side equipment options. The choice follows the IT cooling architecture, room layout and required operating envelope.
Heat rejection & water systems
Cooling towers and fluid coolers, filtration and storage are selected for the relevant system arrangement, water conditions and project requirements.
Design discussion
Start with the operating requirement.
| Requirement | Information to establish before equipment selection |
|---|---|
| Load & development stage | Design cooling load, rack-density information where applicable, present load and phased expansion plan. |
| Cooling architecture | Air-cooled or liquid-cooled IT arrangements, proposed heat-removal method and system boundaries. |
| Environmental conditions | Required air/liquid temperatures, humidity criteria, site ambient conditions and operating profiles. |
| Resilience & maintainability | Required availability outcome, maintenance isolation, failure scenarios and cooling continuity criteria. |
| Site resources | Water availability and quality, space, access, electrical supply and environmental constraints. |
| Interfaces & acceptance | Mechanical/electrical/controls responsibilities, testing requirements, witnessing and acceptance criteria. |
Delivery & verification
Define the interfaces before selection.
A coordinated equipment package needs clear responsibility at each connection and operating interface. Use the project proposal to establish who designs, supplies, installs, connects, controls, tests and accepts each part.
Mechanical & electrical
Confirm hydraulic duties, connections, physical space, power requirements and the responsible parties.
Controls & operating sequences
Define the required control interfaces, operating sequences and points of integration with the wider facility.
Testing & handover
Agree equipment start-up support, functional tests, any integrated testing, witness points, records and operator handover requirements.
Application-dependent options
Backup cooling is a system decision.
ICE-CEL thermal storage is an option to assess after the cooling architecture, operating duty and required backup duration are established. It is not a substitute for defining the complete cooling-continuity arrangement.
- Storage must be charged and sized for the required cooling duty and duration.
- Controls and backed-up power for the necessary pumps and cooling terminals must be addressed.
- Ice charging requires suitable chiller and fluid selection.
- Hybrid and liquid-cooling interfaces require project-specific selection and engineering confirmation.
The portfolio does not establish a complete validated CDU, cold-plate or immersion package. The website makes no Tier certification, uptime guarantee or whole-facility performance claim.
Next step
Build an equipment enquiry that can be assessed.
Share the load, temperatures, cooling architecture, development stage, site constraints and resilience objectives. Ask the team to identify the equipment package, technical documentation and interfaces applicable to your scope.
