Heatwave – Data Centre Emergency Chiller
The Challenge
During a record-breaking summer heat wave, a key client contacted Celsius Hire in urgent need of support. Their on-site server room was experiencing rising internal temperatures due to prolonged heat and an underperforming in-house cooling system. With sensitive equipment at risk and system alerts already triggering, immediate action was required to prevent downtime and potential damage.
The site’s existing air conditioning simply couldn’t keep up, and the internal temperatures were approaching the upper limit for safe operation. The client needed a fast, reliable, and temporary cooling solution to stabilise the environment and protect their infrastructure.

The Solution
Celsius Hire responded immediately with a same-day site assessment. Following a detailed review of the space, access points, and safety measures, the team specified and deployed a temporary 125kW chiller unit connected to an 150KW Air Handling Unit to provide cold air to the space.
The Air Handling Unit was positioned externally, with flexible ductwork routed to a modified air intake to the server room.
The entire system was commissioned and operational within hours of delivery.
- 1 x 125KW Chillers
- 1 x 150KW AHUs
- Flexible Hoses
- 50m of Flexible Ducting
The Result
The server room temperature stabilised within a few hours of the equipment going live. Temperatures remained well within recommended operating ranges for the duration of the heatwave, avoiding any loss of data or functionality.
The client was extremely satisfied with both the speed of response and the professionalism of the install.
“It was a textbook example of rapid chiller hire deployment under pressure. The team were onsite within hours, and our temporary chiller system was up and running on the same day. The client avoided downtime and had peace of mind through the most intense days of the heatwave.”

Cooling Solutions and Heat Load Testing
In our increasingly digital world, data centres form the backbone of virtually every industry; from finance to streaming services to cloud storage. As the demand for data storage and processing grows, so does the need for highly reliable cooling systems. At Celsius Hire, we specialise in providing temporary and scalable cooling solutions; as well as heat load testing services tailored specifically for data centres.
Why Cooling is Critical in Data Centres
Data centres operate high-performance computing equipment that generates substantial heat. Without adequate cooling, temperatures can rise rapidly, leading to equipment failure, reduced performance and even service outages. In an environment where uptime is critical, effective thermal management is vital.
