Industrial Expansion Tanks
AquaX HVAC Expansion Tanks
Stainless & Carbon Steel Bladder / Diaphragm Tanks for Closed-Loop Systems(subline)
Description
AquaX HVAC Expansion Tanks are engineered to manage thermal expansion in closed-loop hydronic and HVAC systems by maintaining stable system pressure and protecting critical equipment. As water heats and expands, the tank absorbs excess volume to prevent pressure spikes, reduce stress on pumps and piping, and extend overall system life.
Designed for durability and long-term reliability, AquaX expansion tanks are ideal for data centers, commercial buildings, central plants, and industrial facilities where system stability and uptime are critical.
