Amtrol Inc products

Amtrol invented the first pre-pressurized well tank over 50 years ago as a better solution to traditional air-over-water tanks. This revolutionary product featured an innovative design that uses a hoop ring and groove to lock the diaphragm, liner and shell together. Today, Well-X-Trol is still the standard of the industry with many unique features including high strength steel to deliver 150 PSIG working pressure, patented Turbulator water circulator device and antimicrobial liner that neutralizes bacteria on contact. Well-X-Trol is the world’s most trusted brand of well tanks, backed by an industry leading 7-year limited warranty.

Champion, Wel-Flo and Pro-Line fixed diaphragm well tanks are the high quality alternative to other designs. They deliver reliable performance at an affordable price. All feature 125 PSIG working pressure, a stainless steel connector, patented Turbulator^® and a 5-year limited warranty. These brands represent an outstanding value compared to competitive well tanks.

Designed for use in closed, potable hot water systems, Therm-X-Span accepts expanded water as system temperature rises. This hot water is returned to the system when demand occurs. A thermal expansion tank, like Therm-X-Span, is essential in a closed system to protect your water heater.

Nearly seven decades after inventing the Extrol, the first diaphragm expansion tank, Amtrol’s lineup now includes the Extrol Pro. This next generation expansion tank is engineered for modern, high-efficiency systems including hydronic, solar and radiant systems. The Extrol Pro is The One That Does It All.

Extrol expansion tanks accept expanded fluid in closed-loop hydronic systems to control pressure buildup, improve comfort and help reduce energy costs. Nearly seven decades after inventing the first diaphragm expansion tank, Amtrol’s lineup now includes specialty models engineered for modern, high-efficiency systems. None of it would have been possible without Extrol – The One That Started It All.

Extrol ASME commercial expansion tanks are designed to control pressure in closed hydronic heating & cooling systems. Available in diaphragm, partial acceptance bladder and full acceptance bladder designs, these tanks range in size from 6.4 gallons (24 liters) to 3,963 gallons (15,000 liters). Offered with maximum working pressures up to 300 PSIG (21 bar), Extrol is effective at maintaining positive pressure in a wide variety of HVAC systems.

Amtrol ASME tangential air separators are designed to create a low velocity vortex that separates and removes entrained air from fluids circulating in closed, heating and chilled water systems. Available in 1” to 24” sizes with optional stainless steel strainer to collect unwanted system debris.
