Centralized cooling projects for large factories require high standards on continuous operation, high cooling capacity, multi-unit linkage control, bulk delivery and after-sales maintenance. These systems are widely used in injection molding, new energy, mechanical processing and new material industries. Based on practical project experience, this article lists ten domestic industrial chiller manufacturers as reference for large plant central cooling selection. When choosing suppliers, focus on system solution capability, linkage control, delivery capacity and local after-sales response.
