Secure I.T. Environments (SITE) has enabled Royal Devon University Healthcare NHS Foundation Trust to dramatically reduce energy costs and achieve ROI in under three years.
SITE, the UK-based design and build company for modular, containerised, and micro data centres, completed the data centre cooling upgrades that led to this achievement.
Replacing the data centre cooling infrastructure
The works, which are the latest in a series of projects SITE has conducted for the trust in recent years, replace existing cooling infrastructure with three new indoor units that improve efficiency.
The free cooling solution, allows the data centre to operate in a higher temperature-free cooling configuration for a greater proportion of the year, taking advantage of ambient temperatures and lowering running costs.
Each unit combines direct expansion air cooling and an energy-efficient FreeCool circuit, as well as including built-in compressors for the direct expansion circuit.
The new installation is projected to enable the data centre to achieve a PUE of 1.14, and Cooling PUE of 1.10
External Hybrid Heat Rejection (HHR) units were also fitted on-site.
The new installation is projected to enable the data centre to achieve a PUE of 1.14, and Cooling PUE of 1.10.
The installation was conducted over three phases, ensuring the data centre could remain live supporting hospital and patient services.
Secure I.T. Environments was responsible for the decommissioning of existing units, and installation of new equipment, including electrical works, configuration, and testing.

Chris Wellfair, Projects Director at Secure I.T. Environments, said: “The primary source of operating expenditure (OPEX) for data centres is electricity. Whilst maintaining the climate conditions within a data centre is critical, the ASHRAE TC9.9 2016 thermal guidelines now give confidence to operators that they can control the indoor temperature at higher levels.”
“This combined with the efficiencies gained with new equipment will dramatically lower energy costs at RDEF and achieve a return on investment in under three years,” Wellfair concluded.
