How to choose data center liquid cooling companies?

Choosing data center liquid cooling companies requires comprehensive consideration of technical strength, product performance, compatibility, service response, and long-term costs, especially in the current high-density development of AI computing power, where liquid cooling has changed from an "optional" to a "mandatory" option. Based on industry trends and user feedback in 2026, the following are the core dimensions of scientific selection:
1. Check the technical strength and research and development background
Priority should be given to enterprises with independent research and development capabilities and participation in industry standard setting.
Do you have a provincial-level or national level research and development platform? Ruofei Corporation owns the Hebei Industrial Refrigeration Equipment Industry Technology Research Institute, which has a deep technical accumulation.
Have you mastered the core component technology? Such as cold plate processing accuracy (± 0.01mm), self-developed ability of CDU (coolant distribution unit), etc.
Do you have the capability of dual technology roadmap? Enterprises with parallel layout of cold plate and immersion systems (such as Envision and Tongfei Corporation) are better suited for future evolution.
2. Check product performance and measured data
Parameters should not only be based on publicity, but also on third-party testing reports and real cases.
PUE performance: A high-quality liquid cooling system can control PUE between 1.12 and 1.2.
Heat dissipation density support: Is it compatible with servers with a density of ≥ 3kW/U or even higher? Zhejiang Chuncheng Cooling and Yingweike both support high-density computing scenarios.
Safety certification: Is the coolant insulated and non flammable? Does the system have leak detection and emergency shutdown functions? Safety is not subject to trial and error.
3. Check compatibility and customization capabilities
The liquid cooling system must be "well fitted" to avoid equipment "fighting".
Does it support CPU/GPU precise cold plate bonding for multi brand servers (such as Huawei, Inspur, Dell)?
Do you provide on-site inspections and customized plans based on the layout of the computer room and future expansion plans?
Can the control system be linked with the existing data center management platform? Open interfaces are key.
4. Check the service network and after-sales support
Liquid cooling is a long-term asset, and after-sales service is more important than pre-sales.
Response speed: Do you promise remote response within 2 hours and on-site visit within 24 hours? User feedback from Tongfei Corporation indicates that problems are resolved within an average of 4 hours.
Localized services: Are there service outlets in the Yangtze River Delta, Pearl River Delta and other regions? Zhejiang Chuncheng Cooling supports on-site installation and lifelong maintenance in Jiangsu, Zhejiang, and Shanghai.
Do you provide maintenance training and regular inspections? A comprehensive after-sales system can reduce long-term risks.
5. Calculate Total Cost of Ownership (TCO)
Don't just look at the initial purchase price, calculate the comprehensive cost for 3-5 years.
Although liquid cooling requires higher initial investment than air cooling, its energy-saving effect is significant. For every 0.1 reduction in PUE, the annual electricity cost can be saved by millions of yuan.
Choosing frequency conversion energy-saving solutions like Jialitu can reduce energy consumption by 15% -20%, making it suitable for the renovation of small and medium-sized data centers.
