Scale Prevention

Unique Products and Services is the Sole Distributor for MHD Magnets in Africa

The magnetic treatment of fluids presents an excellent method of avoiding costly scale formation. Wherever water circulates as a heating or cooling mechanism, in water supply systems, as process water or in chemical manufacturing processes build-up of calcium carbonate, calcium sulphate, iron phosphate and various hydroxides forms a major maintenance headache endangering productivity and operational costs.

MHD Scale Control Technology combines advanced magnetics and fluid dynamics to control the formation of scale in new piping and process equipment preventing blockages and unscheduled shutdowns.
The corrective action entails the proportional dissolving and disintegrating of deposited old scale. These deposits are then carried downstream with the passing fluid.

If left unchecked, scale build-up can seriously increase fuel costs, repair and cleaning costs and downtime.
Magnetic Fluid Treatment provides you with a permanent solution.

After three months trials, the results are clearly visible in the phosphate return lines underneath the cone bottom tanks

Without MHD Magnetic Fluid Treatment:

Tenacious hard scale sticking to the pipe wall

With MHD Magnetic Fluid Treatment:

Soft scale can easily be removed from the pipe wall
