Why Buy From Us
Every quote personally reviewed. Direct sourcing from top manufacturers.
The Amtrol Extrol AX-100V is a commercial-grade, ASME-certified diaphragm expansion tank engineered to control pressure fluctuations in closed, non-potable hydronic heating and chilled water systems. Built with a deep-drawn steel dome design that provides greater strength than traditional head-and-shell construction, the AX-100V isolates a heavy-duty butyl/EPDM diaphragm from system fluid to prevent waterlogging and maintain long-term pressure control.
