Watertech EVO MT 11

The Watertech Presscontrol Evo is a variable frequency pump controller. This model varies the number of motor revolutions of the pump depending on the water withdrawal by the system in order to maintain constant pressure and flow. Presscontrol Evo allows the user to adjust the system pressure and the pump restart pressure. It comes with a range of features to protect the pump including run dry protection and anti-jamming. The features of this controller mean it’s extremely energy efficient. The Presscontrol Evo can be installed on above ground and submersible pumps. There is no need for an expansion tank, check valve, filter or fittings and it is maintenance free. Each model is available with a communications module (COM version) to allow for use with pressure sets.
