Cooling Towers for Data Centres

Cooling towers for data centres reject the heat that servers and IT loads generate, holding temperatures stable and protecting uptime. As rack densities climb, dependable heat rejection is no longer optional. Franklin Hodge designs and manufactures Carter Environmental cooling towers for data centres and other critical sites across the UK and worldwide.

How Cooling Towers Keep Data Centres Running

A data centre turns almost all the power it draws into heat. Cooling towers move that heat out of the building by rejecting it to the atmosphere, usually working alongside chillers. If the cooling system stalls, temperatures rise fast and equipment is at risk within minutes. That is why heat rejection must be reliable, efficient, and sized correctly for the load it serves.

Cooling Tower Options for Data Centre Cooling

Data centres are cooled in different ways, and the right choice depends on your site, climate, and water position. Franklin Hodge offers two main routes. Evaporative cooling towers, the BAL, BUC, and SAN series, deliver high-capacity cooling at 6 to 600 cubic metres per hour, with open and closed-circuit options. Dry air blast coolers, the ABC and WABC series, reject heat without the water use of evaporative towers. If you are upgrading an existing installation rather than building new, our cooling tower refurbishment service can modernise what you already run.

Cutting Water and Energy Use in Data Centre Cooling

Water is now a live issue for data centre operators. Evaporative cooling is effective but consumes water, and both regulators and sustainability targets are tightening. Our dry air blast coolers cut water use sharply, and the WABC adds an adiabatic mode that pre-cools the incoming air on hot days, recovering performance without running wet the whole time. That balance keeps water bills and energy use in check.

Reliability and Legionella Compliance

Uptime depends on cooling that does not fail. Multi-cell configurations build in redundancy, so a single cell can be serviced without taking cooling offline, and stainless steel construction resists corrosion for a long service life. Closed-circuit and dry systems also lower Legionella risk by keeping process water sealed away from the air. Where an evaporative system is in use, planned cooling tower servicing keeps it compliant with your Legionella obligations.

Specifying Data Centre Cooling for Your Site

The right system starts with your numbers. We size each installation around your heat load, your target water temperatures, and the space you have, whether that means a single unit or a multi-cell array. Every Carter Environmental system is built in stainless steel as standard and manufactured at our Birmingham facility, so you get durable equipment and a supplier who can support it for its whole life. Bespoke designs are available where a standard configuration will not fit.
