Amtrol
AMTROL was founded in 1946 on the simple concepts of innovation, quality and service. In 1954, we revolutionized the hydronic industry when we introduced EXTROL®, the world’s first pre-pressurized diaphragm expansion tank. This was followed in 1963 with the invention of the first pre-pressurized well tank and in 1967 with the invention of the refrigerant gas cylinder. AMTROL went on to invent the indirect fired water heater in 1980 and the thermal expansion tank in 1991. Throughout our history, AMTROL has been the world leader in the design and operation of the vital mechanical systems that are used to control hydronic heating and to store potable water.
Today, AMTROL products include a comprehensive array of water system solutions for storage, treatment, heating, expansion and flow control serving the residential and industrial markets. Our products are manufactured in the USA at our ISO 9001:2015 facilities in Rhode Island and Maryland.
