About Data Centre Cooling Systems
Data centre cooling design, installation and maintenance in the UK — CRAC, in-row, rear-door heat exchangers and free-cooling chillers under strict SLAs.
Our data centre cooling systems work in the UK is delivered by directly employed, REFCOM F-Gas registered engineers — never sub-contracted. Every job is priced as a fixed written quote with no hidden extras and finished with a same-day service report covering operating pressures, temperatures, electrical readings and any refrigerant added or recovered.
We work across offices, restaurants, hotels, retail units, schools, clinics, gyms, server rooms and light industrial sites in the UK — from a single split system to multi-floor VRF estates — to manufacturer specification and BESA SFG20 maintenance standards.
Common issues we resolve include weak cooling or heating output, refrigerant leaks, iced coils, blocked condensate drains, error codes and lockouts, noisy fans and compressors, failed PCBs, contactors and capacitors, dirty filters, and controls that no longer match how the building is used.

What People Ask About Data Centre Cooling Systems
How is cooling done in data centres?
Cooling in data centres is achieved using various systems like Computer Room Air Conditioners (CRAC), in-row cooling units, rear-door heat exchangers, and free-cooling chillers. These systems manage heat generated by IT equipment, often circulating chilled water or refrigerant. Our F-Gas certified engineers design and maintain these solutions to ensure optimal temperature control.
Do data centres need cooling?
Yes, data centres absolutely require cooling to dissipate the significant heat generated by servers and other IT equipment. Without effective cooling, components can overheat, leading to performance degradation, system failures, and costly downtime. Our services ensure critical equipment operates within safe temperature limits.
Can data centres be air cooled?
Yes, data centres can be air cooled, typically using CRAC units that cool and circulate air throughout the facility. Other air-based methods include in-row coolers and hot/cold aisle containment strategies. Our F-Gas certified engineers design and install these air cooling systems to maintain stable temperatures for IT infrastructure.
What are the types of data centre cooling systems?
Data centre cooling systems include Computer Room Air Conditioners (CRAC), in-row cooling units, rear-door heat exchangers, and free-cooling chillers. We design, install, and maintain all these types of systems. Our F-Gas certified engineers offer bespoke solutions tailored to specific data centre requirements, ensuring optimal performance and efficiency.
How are data centres cooled with water?
Data centres are cooled with water using systems like chillers, which cool water that is then circulated through CRAC units, in-row coolers, or directly to server racks in liquid cooling applications. Free-cooling chillers leverage outdoor ambient temperatures for efficiency. Our F-Gas certified engineers are expert in these water-based cooling solutions.
What is data centre cooling system design?
Data centre cooling system design involves planning and implementing an efficient thermal management strategy to dissipate heat from IT equipment. This includes selecting appropriate technologies such as CRAC units, in-row coolers, or free-cooling chillers, and optimising their layout and integration for maximum efficiency and redundancy. Our F-Gas certified engineers provide expert design services.
