Description
The Zilmet ZETA-60 is a heavy-duty, ASME-certified hydronic expansion tank designed to maintain stable pressure in large closed-loop heating, cooling, and HVAC systems. With a 40-gallon capacity, this expansion tank is perfect for commercial buildings, multi-zone hydronic networks, or high-demand residential applications. Its fixed butyl diaphragm and durable steel construction ensure reliable long-term performance, protecting boilers, pumps, piping, and heat exchangers from pressure spikes caused by thermal expansion.
