It is the HVAC industry’s first customisable air displacement ventilation ductwork system with onsite directional-adjustability for effectively and energy-efficiently cooling commercial data centre equipment.
Cooling build-outs can be one of the highest operational costs facing data storage facilities. However, executives at San Diego-based redIT says it has implemented a new cost saving measure at its data centres. The new procedure involves adding fabric duct cooling drops for individual partitions inexpensively, and only as new customers come onboard.
To ensure redundant capacity, data centre construction requires a complete and expensive build-out of a space’s HVAC system, including ductwork and diffusers. Because it may take years to lease out the entire space, this upfront cooling build-out can be a costly practice. redIT officials have found a short-term, more cost-effective
alternative by installing each sheet metal drop and diffuser only after a customer comes onboard. This approach postpones construction costs while saving data centres time and resources.
That said, this phased sheet metal construction approach also has disadvantages. Sheetmetal construction creates airborne particulates and poses other unnecessary risks to neighbouring computer equipment. It also costs thousands of dollars in installation labor and material associated with each new cooling drop. Additionally, outsourced sheet metal contractors in highly restricted access control areas can potentially jeopardize security efforts.
redIT, operating multi-tenant facilities with many Fortune 500 clients, realized these challenges. Furthermore, the firm wasn’t satisfied with the prices, performance, or flexibility of conventional CRAC air distribution systems. redIT used this cost-saving phased cooling approach during the build-out of the first 14,800-sq-ft data centre phase of its 88,000-sqft facility in San Diego. The HVAC service contractor, Countywide Mechanical Systems, introduced fabric ductwork to redIT’s design team.

Close Coupled Cooling
Increasing power density is causing major cooling problems for IT equipment in datacenters which traditional downflow computer room air conditioning (CRAC) systems cannot solve.
Datacenter cooling design philosophies have not significantly changed for 30 years, despite advances in server technology. Downflow CRACs are no longer an effective means of cooling low, medium or higher density heat loads.
An immediate remedy is to use close coupled cooling (CCC), with CCC units placed directly in the server racks. Rack based cooling equipment solves the problem by removing heat at the source of production instead of distributing cold air in an attempt to cool the room.
Our intelligent cool features patented technological advances that set a new benchmark for energy, efficiency, flexibility and resilience as recognised by the Carbon Trust:
• Modular Rack Mounting – adjacent to the heat load for maximised capacity and minimised air path, up to 70% lower power consumption
• Row Heat Capture – thermal isolation without the cost or space consumption of containment
• Row Air Curtain – eliminates need for raised floor cold air distribution systems
The superior design of Delta-T close coupled cooling delivers comparable capital cost, but much lower operating cost and footprint compared with room cooling. Resilience and redundancy is enhanced using adaptive environmental control from our BACnet linked digitally driven cooling units.
SemperTec’s Delta-T allows computer cooling to be deployed whenever and wherever required – as part of an upgrade, a complete fit-out or for localised hotspot cooling solutions.
