Because of a very flexible production facility, we are able to manufacture anodes of all types: sheet, plate, mesh, wire, rod, tubular or combinations and/or assemblies of these materials. Their size and number vary from several cm2 to 2 m2 and from 1 to 10,000 pieces. The process in which the anodes are used determines size, shape and coating specification of an anode.
Important parameters determining the anode design are:
◆ The electrochemical cell or installation wherein the anodes are used
◆ The process conditions, such as electrolyte composition, temperature, current density, design life, etc.
◆ Mechanical load of the anode
◆ Capacity of electrical conductivity of the base material.
All anodes are produced according to customer specifications. When these specifications are not yet completely determined, our engineers are pleased to use their knowledge and experience to finalise the design together with the customer.
