Closed Loop Circulation

WILO provides reliable pumping solutions for closed-loop panel cooling systems used in electrical control panels, automation cabinets, VFD panels, PLC enclosures, and power distribution equipment. These systems circulate water or water-glycol mixtures through cooling units, heat exchangers, and panel cooling circuits to remove heat generated by sensitive electronic components. Maintaining a stable operating temperature is essential for ensuring equipment reliability, preventing overheating, and extending component life.

WILO small circulator and inline pumps, including the Yonos PICO and Para series, deliver efficient and continuous coolant circulation with low power consumption and quiet operation. Their compact design allows easy integration into panel cooling units while providing dependable performance in industrial environments. WILO solutions help OEMs achieve improved thermal management, enhanced equipment protection, and long-term operational reliability for critical electrical and automation systems.
