Envirotech's History

In 1995, William Vis was the production manager of Precision Feeds when he began operation of Envirotech Controllers Ltd. as a division of Precision Feeds with one employee. Envirotech Ag Systems Limited was formed in 1998 with the merger of the equipment division of Feed-Rite Ltd. and Envirotech Controllers Ltd. In 2016 Envirotech expanded and opened an office and warehouse in Sioux Falls South Dakota to provide much needed support to the increasing number of US customers.
