Alex-Tronix Since 1977


About Alex-Tronix

Since 1977 Alex-Tronix has been a leading innovator of irrigation controller technology, and manufactured high-quality commercial controllers. From filter backwash to battery operated “Smart” controllers, Alex-Tronix prides itself on manufacturing a reliable controller that holds up in extreme environments. Today the company supplies about 60% of all the filter backwash automation to over 200 distributors and OEM’s throughout the world.


In 2014 Alex-Tronix introduced its new Filter Master series of filter backwash controllers. The Filter Master series has been engineered to provide the latest features and functions while keeping our ease of programming. Our goal is to provide the best filter backwash controller on the market today at a reasonable price. The new FM4 is off to a great start and the customer sentiment has been nothing but positive with this innovative new controller - (that also is less expensive than its predecessor.)


An expansion of the Filter Master series is on the horizon with the new FM 1 and the FM12/16. Look for these new products next year as we expand our line to cover all systems big and small. We look forward to helping manage our water by providing simple, effective controllers that minimize water use in these challenging times. Our hope is that we can continue to partner with our customers in providing solutions that help our farmers manage their water use effectively.
