Start with the cooling system.
For data centre facilities, engineering and energy teams, continuity of service is central to any proposed change. The first conversation is about your plant, access requirements and approval process.
OH4 uses magnetic sheeting fitted externally around commercial cooling and chiller pipework. There is no cutting or draining, no electrical connection to the sheeting and nothing added to the circulating fluid. Your engineer needs to confirm suitability for the proposed pipework and system.
The photograph shows an existing rooftop chiller installation. It illustrates the fitting process, not a named data centre project or a cooling-performance result.
Inside the pipework
Water in motion.
OH4 fits around the outside of existing pipework. Your pilot assesses energy performance using your own meter readings.
A pilot your team can review.
Define the installation
Review pipe material, fluid, operating temperatures, insulation, access and maintenance arrangements. Agree the method of work and your site's permissions before installation.
Agree the comparison
Identify the cooling equipment and meters included. Establish the baseline, monitoring period, operating checks and treatment of changes before the pilot begins.
Review the evidence
Assess the result with your engineering and energy teams. Record limitations, including an inconclusive outcome. Use the pilot to inform any wider installation.
Keep cooling energy separate from IT demand.
A whole-site electricity total does not isolate cooling performance. The pilot plan should identify the cooling loads being assessed and the available metering, rather than treating a change in total site consumption as an OH4 saving.
Record IT load, outdoor conditions, cooling setpoints, plant operating modes and maintenance during the comparison. Agree how relevant differences between the baseline and pilot period will be handled. Show readings separately from calculated adjustments.
For background on defining useful measurement boundaries, see the US Department of Energy's Data Center Metering and Resource Guide.
Bring your cooling team into the conversation.
Tell us about the site, cooling system and meter data available. We will discuss suitability and the next step with your facilities or engineering team.
