Data centers are the central hubs of the digital world, but as artificial intelligence reshapes computing, data centers are running hotter than ever. Traditional air-cooling systems are struggling to keep up with high-density servers, leading to rising energy costs, efficiency losses and costly downtime. To address this challenge, liquid cooling has emerged as a highly effective solution, capable of removing heat far more efficiently and enabling greater computing density beyond what traditional air cooling was built to handle. Ashcroft, together with its parent company Nagano Keiki Co Ltd., is a leading authority in pressure measurement and sensing technologies designed to keep liquid cooling systems safe, efficient and reliable. With decades of expertise across demanding industries, customers trust Ashcroft’s expertise to guide data center operators on selecting the best pressure and temperature instrumentation to ensure a smooth transition to advanced cooling methods. Read this article to learn how liquid cooling works, the different system types available, the benefits they deliver over air cooling and key considerations for implementation.
