In data centres, direct-to-chip liquid cooling relies on fast-acting valves to regulate coolant flow and protect servers from overheating. Yet across server racks operating 24/7, the cumulative energy demand of continuously energised solenoid valves presents cost and sustainability challenges. However, Kick & Drop coil technology offers a solution to this inefficiency by using a high-power ‘kick’ to actuate the valve, followed by a low-energy ‘drop’ to hold position. The design can...

Drew Gravitt is Senior Director of Distributed Generation & Microgrid Sales at Mission Critical Group (MCG) explains how the demand for data centres is surging due to AI and digital services and how this is placing increasing strain on existing power infrastructure. With many data centre developers facing long wait times for grid connections, Drew goes on to discuss the ways in which distributed generation and microgrids can help address the ‘time-to-power’ problem.

Cooling is one of the most expensive operational outlays in data centre operations: reducing its cost and improving Power Usage Effectiveness (PUE) is therefore one of the primary challenges for data centre owners. ‘Free-cooling’, an old technology that’s having a resurgence in popularity, can help with this challenge, but only if it genuinely exploits partial (mixed-mode) operation. Tim Mitchell from Klima-Therm explains why not all ‘free-cooling’ is created equal, and what owners...
