Not sure which system you need? Most small business server rooms (1-3 racks) do well with a wall-mounted split or ceiling cassette. For rooms with 4+ racks or high-density computing, in-row cooling delivers the best efficiency. Our free site survey will assess your exact requirements and recommend the right solution.
Server Room Cooling Performance
What modern precision cooling achieves for your IT infrastructure
Precision systems maintain your target temperature within ±1°C across the entire room, preventing hotspots and cold spots
Integrated humidity control prevents condensation damage and static discharge, protecting your valuable equipment
Modern precision cooling can reduce your PUE from the UK average of 2.0 down to 1.3-1.5, cutting energy waste significantly
Energy Saving Tips for Server Room Cooling
Implement hot/cold aisle containment to prevent air mixing and reduce cooling load by up to 30%
Raise set temperature to 25°C (ASHRAE allowable range) — every 1°C increase saves 4-5% on cooling energy
Use blanking panels in empty rack spaces to stop hot air recirculating through unused gaps
Consider free cooling economisers for UK climates — outside air can supplement cooling for 6+ months of the year

Common Questions About Server Room Cooling
Everything you need to know about server room cooling and IT climate control
What temperature should a server room be kept at?
The ideal temperature range for a server room is between 18-27°C (64-80°F). This follows ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommendations.
This range balances optimal server performance with energy efficiency. Maintaining temperatures within this band helps prevent equipment overheating while avoiding unnecessary cooling costs. Our precision cooling systems can maintain temperatures consistently within ±1°C of your target setting.
Why is humidity control important in server rooms?
Humidity control is crucial in server environments to prevent both condensation and static electricity. The recommended relative humidity range is 40-60%.
Excessive humidity can cause condensation that damages electronic components. Too little humidity increases the risk of electrostatic discharge (ESD) that can harm sensitive equipment. Our precision cooling systems include integrated humidity control to maintain optimal conditions at all times.
How much cooling capacity does my server room need?
Cooling requirements depend on several factors including room size, equipment heat output (measured in kW or BTU), density of equipment, insulation, and external heat sources. As a rough guide, modern servers generate 400-800W of heat per unit.
A professional heat load calculation is essential for accurate sizing. Our free site survey includes a comprehensive heat load assessment to determine the precise cooling capacity your server room needs.
What happens if server room cooling fails?
Cooling system failure can quickly lead to severe consequences including equipment shutdowns, hardware damage, data loss, and extended downtime. Without adequate cooling, server room temperatures can rise by 1-2°C per minute.
Our solutions include redundant systems, real-time monitoring with alerts, and emergency response services to provide peace of mind. We offer 24/7 emergency callout service for critical cooling system failures across Sussex and Surrey.
What types of cooling systems are available for server rooms?
The main types of server room cooling are wall-mounted split systems (ideal for small server closets under 15m²), in-row cooling units (placed between racks for high-density environments), precision PAC/CRAC units (purpose-built computer room air conditioning with tight temperature and humidity control), and ceiling-mounted cassettes (for medium rooms with suspended ceilings).
Free cooling systems that use outside air when temperatures allow can also supplement your primary cooling. We assess your specific requirements during a free site survey to recommend the most efficient solution.
How much does server room cooling cost to install?
Server room cooling costs vary based on room size, heat load, and system type. A wall-mounted split system for a small server closet typically costs £1,500-£3,000 installed. In-row cooling for a medium server room ranges from £5,000-£15,000. Precision PAC units for larger data centres start from £8,000-£25,000+.
All our quotes include a free site survey with detailed heat load calculation, so you get an accurate price before committing.
What is PUE and why does it matter?
PUE (Power Usage Effectiveness) measures how efficiently a data centre uses energy. It's calculated by dividing total facility power by IT equipment power. A PUE of 1.0 would mean all power goes directly to computing — in practice, 1.2-1.5 is considered efficient.
The average UK server room has a PUE of around 2.0, meaning half the energy is wasted on cooling and overhead. Modern precision cooling systems can help achieve a PUE of 1.3-1.5, significantly reducing your electricity bills.
Can you retrofit cooling into an existing server room?
Yes, we regularly retrofit precision cooling into existing server rooms and IT spaces. This includes upgrading from standard air conditioning to purpose-built server room cooling, adding supplementary capacity as your IT equipment grows, installing hot/cold aisle containment, and adding humidity control.
We work around your operating schedule to minimise downtime — most retrofits can be completed with zero disruption to your IT operations.
How do in-row cooling systems differ from traditional AC?
In-row cooling units sit directly between server racks, drawing hot exhaust air immediately at the source rather than cooling the entire room. This close-coupled approach is 30-40% more energy efficient than traditional perimeter cooling because cool air travels inches rather than metres.
In-row units also respond faster to heat load changes, provide better temperature uniformity across racks, and allow higher rack densities. They're ideal for server rooms with 5kW+ per rack.
What size server room needs dedicated cooling?
Any room with more than 2-3 servers or networking equipment generating over 2kW of heat should have dedicated cooling rather than relying on building air conditioning. Even a small server closet with a single rack can overheat quickly — standard office AC isn't designed for the concentrated, continuous heat loads that IT equipment produces.
Signs you need dedicated cooling include ambient temperatures regularly exceeding 25°C, equipment fans running at full speed constantly, or thermal shutdown warnings.
Do you offer maintenance contracts for server room cooling?
Yes, we offer tailored maintenance contracts for server room cooling systems. Regular servicing typically includes filter replacement, refrigerant checks, condenser cleaning, control system calibration, and humidity sensor verification.
For critical environments we recommend quarterly servicing, while less critical rooms may only need biannual visits. All contracts include priority emergency response.
What areas do you cover for server room cooling?
We provide server room cooling services across Sussex and Surrey, including Brighton, Hove, Worthing, Crawley, Horsham, Chichester, Eastbourne, Hastings, Guildford, and surrounding areas. For larger commercial projects, we cover the wider South East including London.
Our 24/7 emergency response service covers all areas within our service region.
