POWERMAG Electromagnetic Scale Inhibitor

Protect key plant and equipment with the technologically advanced Liff Powermag scale inhibitor


The Powermag electromagnetic scale inhibitor range offers an alternative approach to limescale control and management. Chemical free operation ensures the composition of the treated water remains unchanged. The simple design aids straightforward installation on pipe sizes from 3/4” to 4” with no appreciable drop in feed water pressure or the need for a bypass. There are seven models within the standard range, suitable for  flow rates from 1.8 to over 100 metres cubed per hour.

The Powermag is manufactured from low carbon steel tubing and is protected from corrosion by a WRAS approved surface coating. All models are supplied with a separate control panel and LCD display.
