IMPORTANT: The AMTROL Selection Tool should be used as a general guide to sizing AMTROL products. Sizing calculations are dependent on user input and should be considered as recommendations. A licensed plumbing contractor, qualified project manager, or facility engineer should verify all sizing selections before purchase and installation.
Therm-X-Trol expansion tanks are designed to control pressure and absorb expanded water in closed, potable hot water systems.
Extrol expansion tanks accept expanded fluid in closed-loop hydronic systems to control pressure buildup, improve comfort, and help reduce energy costs.
Well-X-Trol well tanks are engineered to reduce pump activations and ensure minimum pump run time in well systems. Also, they can provide volume for high-pressure booster pump applications and reduce pump surge.
Fire-X-Trol ASME expansion tanks prevent damage to fire protection systems by accommodating the expanded volume of system fluids that result from temperature changes.
