KAB - Sludge filter - 1

Sludge Filter KAB Applications KAB has been developed for the purpose of removing particles caused by corrosion of heating/cooling applications. This system is designed specifically for use in new and existing installations and networks. Principle Iron oxide can easily be identified in an installation. It settles out in the form of black sludge and is made of dissolved iron precipitated as hydroxide. This hydroxide releases hydrogen and turns into magnetised oxide Fe3O4 also called magnetite. The size (0.5 ì) and density of this product do not allow for an efficient settlement or centrifugal separation. KAB uses magnetic bars to remove these magnetised particles. Working Principle The water held in the pipework is bypassed through a set of multi-field magnetic bars. The low speed flow and the laminar flow enable KAB to retain 99.9% of magnetised particles of less than 0.5 micron. The particles then agglomerate and form a deposit on the magnetic bars. This deposit then enables the trapping of the non-magnetised particles thanks to their position around the magnetic bars. This results in the settling of particles in the installations and circulation of treated water. KAB will bypass 20% of the water flow of the installation and may operate 24 hours a day. Advantages – Compact and easy to install. – Easily cleaned by simply wiping the magnetic bars. – High efficiency enabling the treatment of particles of less than 0.5µ. – No risk of leakage or heating/cooling shutdown during treatment – With the optional isolating valve, minimal water loss while cleaning. – It can be used as an injection cylinder when chemical treatment is required (ex: pH rectifier, oxygen reducer) Options 50µm removable mesh strainer. Feed pump to prevent disruption of an existing installation. Isolating valve. Description KAB is made of a carbon steel cylindrical body with a tangential water inlet at the top. The water outlet is located at the bottom. The multi-field magnetic bars are assembled radially in a gasket that can easily be removed for maintenance. The shape and assembly of KAB creates a cyclonic effect where all the particles are driven to the magnetic bars and to the bottom of the body thanks to the rotational effect and gravity. The magnetic bars will catch the magnetite whereas the nonmagnetised particles will be trapped by settling.
