Oct 03, 2019 In 1954, Amtrol invented the thermal expansion tank to control pressure build-up in closed, hot water systems. Today they are continuing to roll out efficient and reliable tanks to improve your system. The ST in-line thermal expansion tank is a perfect example of this.

WELL-X-TROL®Professional
revolutionizes
the industry
WELL-X-TROL®Professional redefined the industry with its advanced engineering and innovative product design including the pre-pressurized well tank, sealed-in air charge, and unique water chamber design. With proven performance since 1963, WELL-X-TROL
Professional continues to deliver unparalleled results making it the most trusted choice of professionals in today’s market.WELL-X-TROL Professional offers many unique features that result in consistent, reliable performance, including design elements that prevent tank corrosion and reduce wear and tear on the well pump.
Features and Benefits
Exclusive butyl diaphragm, along with the 100% corrosion resistant virgin polypropylene liner, are secured by a positive hoop ring seal for added strength and reliability. This totally integrated system outperforms other types of water chamber designs.
The stainless steel air valve is welded rather than threaded to prevent loss of air pressure.
The finest quality, custom mill steel is used in the deep drawn dome for extra strength while keeping tank weight to a minimum.
More choices mean more flexibility
WELL-X-TROL Professional offers more options and sizes than any other well tank manufacturer, including both
vertical and horizontal designs, and sizes ranging from 2 gallons to 119 gallons so you can configure a system that’s right for any application.
First on Industry Safety
Standards
WELL-X-TROL Professional tanks were the first to meet all industry standards for quality and safety. The butyl diaphragm in all models meets EPA requirements for potable water as defined in the Safe Drinking Water Act of 1986. The entire tank which includes the virgin polypropylene liner, butyl diaphragm, and acceptance fittings for a 100% corrosion resistant water reservoir is listed by NSF International Standard 61.
Advanced
design features
continue to set industry standards
■Stainless steel air valve is welded in position rather than mechanically threaded to prevent loss of air pressure and to minimize stress on the well’s pump system. It also carries a tamper-evident warning label.
■Deep-drawn steel domes offer twice the strength of rolled steel while minimizing weight.
■Unique positive hoop ring seal secures diaphragm and liner for added strength and reliability.
■Heavy duty butyl diaphragm features seamless construction for uniform strength and flexibility. It conforms exactly to the shell configuration without stretching, creasing, or forming bubbles or corners that could trap water or sediment. Butyl is the best known elastomer to prevent air loss.
■Heavy duty butyl diaphragm is extremely resistant to bacterial growth and meets FDA requirements for potable water supply.
■Virgin polypropylene liner provides a 100% corrosion resistant, non-metallic rigid water reservoir that is listed by NSF International Standard 61.
■Stainless-steel system connection withstands aggressive water.
■Exclusive welding process eliminates interior rough spots and sharp edges which prevent damage to the diaphragm and liner.
■Each finished tank is pressure tested for safety.
■Each finished tank is pre-pressurized to the most common pump cut-in pressure.
■Exterior appliance-like finish looks attractive while protecting the tank from the elements.

esp(Effective System Protection):
maximum system output with
minimal pump starts
The ESP sizing procedure covers modern residential water-use habits, increased off-peak demands and the general increase in water use that have occurred over the past twenty-five years. ESP sizing is designed to reduce pump wear and tear, and reduce energy consumption by keeping pump starts to a minimum.
Choose the amount of protection you need.
ESP I: Tank selection is based on approximately one minute minimum pump running time. This is recommended for pumps up to 3/4 H.P.
ESP II: Tank selection is based on approximately two minute minimum pump running time. This is recommended for 3/4 H.P. or larger pumps.

tank operation
time-tested design
WELL-X-TROL Professional1has a sealed in air chamber that is pre-pressurized before it leaves our factory. Air and water do not mix.
2When the pump starts, water enters the WELL-X-TROL Professional. Only usable water is stored.
When the pressure3in the chamber reaches cut-out pressure, the pump stops. The WELL-X-TROL Professional is filled.
When water is demanded, pressure in the air chamber forces water into the system. Since WELL-X-TROL Professional consistently delivers the maximum usable water, minimum
4pump starts are assured.
