Secure I.T. Environments completes telecoms data centre cooling upgrade

By AI, Created 9:13 AM UTC, May 18, 2026, /AGP/ – Secure I.T. Environments says it finished a cooling infrastructure upgrade for a UK telecommunications provider’s mission-critical data hall without service disruption. The project replaced aging air conditioning units with three free-cooling systems that cut projected energy costs by 69% and delivered a 1.29-year return on investment.

Why it matters: - The upgrade targets a live 24/7/365 telecoms data hall, where cooling failures can affect customer service. - The new system is projected to cut energy costs by 69% a year. - Secure I.T. Environments says the project reached a Cooling PUE of 1.13 and a payback period of 1.29 years. - The work shows how older data centre cooling systems can be replaced without interrupting critical services.

What happened: - Secure I.T. Environments completed an offshore cooling infrastructure upgrade for one of the UK’s leading telecommunications providers. - The project replaced end-of-life air conditioning units with three energy-efficient free-cooling units. - The upgrade was completed with no downtime and no break in customer services. - The company announced the completion on May 19, 2026.

The details: - The installation used three indoor Multi-DENCO® DMF065D Downflow Air Conditioning units. - Each unit provides 59.7kW net sensible cooling. - The Multi Denco range operates under typical conditions with a sensible heat ratio of 1.0. - The energy-efficiency gains come from optimized use of the internal inverter compressor, EEV and fans. - The inverter drive varies compressor output to match cooling demand. - The system is designed to deliver higher efficiency, especially at partial load. - The existing cooling units were approaching 20 years old. - Chris Wellfair, Projects Director at Secure I.T. Environments, said the advances in data centre cooling equipment deliver substantially improved energy efficiency and a rapid return on investment. - Wellfair added that these projects can improve resilience and reduce operating costs when delivered with the right partner.

Between the lines: - The project highlights a growing pressure on operators to reduce power use in mission-critical infrastructure. - Free cooling can lower operating costs while also supporting sustainability targets. - The no-disruption delivery matters as much as the energy savings in telecoms environments, where uptime is a core requirement.

What’s next: - Secure I.T. Environments is likely to keep pitching similar upgrades to operators running older data hall cooling estates. - The company’s broader modular, containerised and micro data centre business suggests more work around resilient infrastructure and mechanical and electrical systems. - The new cooling setup will continue serving the telecoms site as the operator tracks energy and performance gains.

The bottom line: - Secure I.T. Environments says the project pairs lower energy use with fast payback, while keeping a mission-critical telecoms site online.
