Becs Controller

BECs has been designing and manufacturing the industry's most reliable and innovative water chemistry controllers for nearly 20 years. Perhaps you thought BECS was new to the aquatics marketplace... In the 1980's, their controllers were sold by Morr Control, based in Muskogee, Oklahoma. The SystemT and SystemT+ were some of the earliest microprocessor-based controllers to be developed and offered in the aquatics industry. In 2005, BECS introduced the BECSys line of water chemistry controllers while continuing the history of reliability commonly known within the industry, these products offer a rich set of features that redefines the standard for water chemistry controllers.
