When processing limestone, some production lines easily reach over 1000 tonnes per hour with well-shaped aggregates and controllable stone powder content. In contrast, other lines struggle with low throughput, high equipment wear and excessive flaky particles in final products. The root cause usually lies not in the raw stone, but in equipment selection and process desig...
On the same day Inspur disclosed a RMB 9 billion private placement with RMB 1.4 billion for a liquid-cooled native computing project, Jiangsu Leili revealed rack-mounted CDU canned pumps in mass production across seven power specs—two very different companies racing into the same link. The orders explain why: global CDU orders are booked into late 2026 and 2027, delivery...
At the center of liquid cooling sits the CDU—integrating pump, heat exchanger, sensors and control in a closed loop—and Zhuomao Instruments offers a complete qualification line: performance testing, aging testing, re-testing, cleaning and drying, and vacuum nitrogen filling with pressure holding. Performance testing covers 0-500 LPM at ±0.5% F.S., 0-1000 kPa at ±0.25% F....
The right CDU route is now the first design decision for any new data center deployment, and air-to-liquid units use an air-cooled radiator to assist the liquid loop without facility water, suiting small and medium data centers, cool climates and budget-limited projects, while liquid-to-liquid units transfer heat through a heat exchanger between primary chilled water and...

With NVIDIA H200 and B200 single-GPU power exceeding 700W, traditional air cooling has reached its operational limit, making liquid cooling a mandatory infrastructure. Once single-rack power exceeds 50kW, air-cooling efficiency collapses and noise exceeds 80 decibels, while liquid cooling triples heat dissipation efficiency and supports 800W+ chips. Three routes serve: d...
While hyperscale campuses of 100MW to GW scale dominate AI infrastructure headlines, Kirk Killian highlights that enterprise data centers—operating at 0.25MW to 10MW but 50 to 100 times more numerous—are the underrated growth engine. AI inference, driven by data security, compliance and sovereignty requirements, is increasingly deployed locally and is expected to far exc...
With single-GPU power past 1kW and rack heat density above 100kW, NVIDIA's certified CDU list (September 2, 2026) names 19 vendors and 28 models as the benchmark of high-density liquid cooling.
