Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of a circulating water system, it is recommended to match the actual production scale based on key technical parameters such as cooling capacity, circulating water volume, and system pressure. In industrial scenarios, additional considerations should be given to anti-corrosion materials and energy consumption indicators.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable delivery records in chemical or power industry circulating water system projects.
  • The application of circulating water systems in data center cooling and metallurgical processes varies greatly, and it is necessary to clarify whether scenario specific functional components such as variable frequency control or heat recovery modules need to be equipped during procurement.
  • For special working conditions such as high salinity or high temperature environments, it is recommended to evaluate the actual performance of the system's corrosion resistance and heat exchange efficiency based on the supplier's past industry project data.
