Chiller Controller PL-M2000-CHL
Our M2000 Chiller Controllers are engineered to provide versatile management for both air-cooled and water-cooled systems. With support for up to four total stages of chiller control, alongside integrated logic for pump management and system water pressure optimization, Prolon offers the flexibility needed for diverse mechanical layouts. As with our entire product lineup, these controllers come equipped with a comprehensive suite of safety and efficiency strategies, allowing you to fine-tune your sequence of operations for peak performance and reliability.
The M2000 adds additional capability for larger and more complex systems, including a timeclock for independent scheduling.
