ATS 165 EP (ACS Certified)


The ATS 165 EP is a robust float switch ACS certified constructed with special components for use in extremely agitated drinking water applications. Thanks to its big switching angle of 165º, this float ensures no jerking of the pump or electrical panels, and it is an ideal solution for level control in drinking water tower tanks. The ATS 165 EP is equipped with a stainless steel (AISI 316L) adjustable ballast, and it can be connected directly to pumps up to 1.5 HP or through a relay if working with high power pumps.
