What do HVAC chillers most often come equipped with?

HVAC chillers are most often equipped with factory-installed Programmable Logic Controllers (PLCs) because these devices offer advanced control capabilities, allowing for precise regulation of cooling processes. PLCs are integral in automating the operation of chillers, enabling them to efficiently respond to varying load conditions and operational demands. This automation enhances the chiller’s performance, provides real-time monitoring, and improves energy efficiency, making them more suitable for modern HVAC systems where control and reliability are essential.

While manual controls, external monitoring systems, and standard on/off switches may play roles in some scenarios, they do not provide the same level of sophistication and flexibility that PLCs do. Manual controls can lead to inconsistent operation and increased labor costs, external monitoring systems typically require additional equipment, and standard on/off switches lack the capability for optimized performance management compared to a PLC. Therefore, it is clear that factory-installed PLCs represent the standard for HVAC chillers, making them the best choice among the options provided.
