Description
The Zilmet ZS12 is a compact, high-efficiency hydraulic separator designed to stabilize flow, eliminate air, and capture system debris in small to medium hydronic heating and cooling systems. By decoupling the primary and secondary circuits, the ZS12 ensures pumps operate without conflict and helps maintain optimal performance across boilers, radiant manifolds, and fan coil loops.
Engineered with robust construction and built-in separation technology, the ZS12 enhances efficiency, extends equipment life, and simplifies modern hydronic system design.
