DC Rectifier

Rectifiers (Switchmode Technology)

The Switch Mode Rectifier is the most efficient Rectifier, offering low energy loss & excellent ripple (< 250mV across the range). Switch Mode power supplies are used in Hospitals, Operating theatres and in life support equipment, satellites, storage tank ICCP Systems & Pipeline ICCP systems.

Switchmode Cathodic Protection rectifiers can typically be used with corrosion protection pipelines, tank farms and other vulnerable metals that are at risk of corrosion where impressed DC currents are required.

We have been developing and supplying CP Rectifiers since 1992. We offer rectifiers in Auto as well as Manual (Hermetically sealed Multiturn Potentiometer) operation. Auto operation in 3 control user-programmable modes – Constant output voltage, Constant output current – Constant Structure to electrolyte potential. User programable parameter limiting renders Cathtect Auto rectifiers as the most state of the art available and its intuitive menu-driven setup simple to use.

We are also happy to engage with you on your specific needs should they not be listed here.

Switchmode Rectifiers, renowned for their reliability and small footprint, are used wherever metal structures such as pipelines are at risk of environmentally induced corrosion.

Oil-Cooled Rectifiers

Rugged and robust harsh environments generally require a Rectifier solution capable of meeting and operating in the extreme environment with very little or no maintenance. The Cathtect Oil Cooled Rectifier should be your first and only choice!

In our most basic enclosures, we utilize a chrome rich Mild steel capable of sea front deployment as well as Stainless enclosures with both our “On Line” and “Off Line” ONAN series rectifiers.

As harsh environments differ and vary, call us, as we are original equipment supplier and are able to meet your most rigorous requirements to deliver a solution tailored to meet the most arduous of locations. We can sherardize, galvanize, powder coat and wet spray to make rugged harsh environment equipment not just functional and fit for purpose, but pleasing to the eye!

See more specifications below, and let us know what your requirements are in your request.

Oil Cooled Cathodic Protection Rectifiers are used in areas with severe weather conditions where Standard Air Cooled Rectifiers will not withstand these conditions.
