What is the difference between a modular chiller and a standard air-cooled chiller?

A modular chiller differs from a standard air-cooled chiller mainly in structure, scalability, and operational flexibility. A standard air-cooled chiller is a single, integrated unit designed for fixed cooling capacity, suitable for medium to large-scale applications with steady load demands. In contrast, a modular chiller system consists of multiple independent modules that can operate individually or together, allowing for flexible capacity expansion and higher system redundancy. Each module includes a complete refrigeration cycle, enabling the system to automatically adjust its output according to real-time load requirements — achieving greater energy efficiency and reliability. Modular chillers are easier to transport, install, and maintain, making them ideal for projects requiring phased construction or future capacity upgrades. Additionally, their distributed design reduces downtime risk — if one module requires service, others can continue running. Aurashu’s modular chillers integrate intelligent control and networking functions for smart, efficient, and scalable cooling management.
