Anode Cells For Electrocoating

Tubular Anodes

Tectron® tubular anodes can be manufactured in a wide variety of qualities, dimensions and options, the ideal mix of product properties are available to optimise each individual electrocoat plant.

The Tectron® tubular anodes use a licensed technology for the internal anolyte flow pattern. This feature means that a relatively high percentage of the ion exchange membrane is available for the electrical current, which is an important quality aspect of the anodes. The chance that biological and corrosion sediments will blind the membrane is reduced, significantly.

Tectron® tubular anodes are heat-sealed, twice, achieving almost absolute reliability. Accessories for these anodes, such as mounting supports, flow indicators and blocking diodes are available which make for an improved ease of installation.

Tectron® tubular anodes offer the customer improved efficiency, lower electrical resistance and overall lower the operating cost of the electrocoating plant.

Membracon are able to assist in the design of the complete anode system, based around the use of the Tectron® tubular anodes. Four anode diameters, 48mm, 60mm, 73mm & 89mm along with lengths to suit each, individual customers’ requirements.

Flat Cell Anodes

Tectron® flat cell anodes are provided with coated steel support bars, the distance between which is optimised to the anode length.

All the dimensions of the Tectron® flat cell anodes are available for customisation for each individual customers’ electrocoating plant requirements.

A “top-open” version allows for easy electrode insertion, removal and general inspection.

Mounting racks can be designed and manufactured to suit any existing paint tank rim support.

Advantages of the use of Tectron® flat cell anodes, include;

Greater electrode area, therefore fewer anodes required, along with fewer electrical & anolyte connections.
The electrode can be easily removed from a “top-open” anode.
Distance from the paint tank wall kept to a minimum.
Two anolyte feed & return connections for improved anolyte flow pattern.

Test, Monitor & Repair Anodes

All manor of anodes can be serviced and repaired via the Membracon technical support personnel, including the replacement of worn or damaged electrodes and membranes.

Onsite inspection of anode installations can be carried out, with a comprehensive report being provided to allow customers to evaluate the maintenance required for optimal paint tank performance.

Membracon’s anode system service, utilising the TruIDL Data Logging unit for electrocoating plants, shows customers where, in the electrocoat tank, the paint film is formed and on which section of the coated components.

At the same time the characteristics from the graphs produced reveal problems in the anode system such as rectifier ripple, loose electrical connections or anode cells which have a high electrical resistance.

Running the service on a regular basis, one to four times a year, and comparing the various curves from previous data shows the effects of ageing of the anode membrane on the efficiency of the anode system.

Our service enables customers to understand in depth the deposition process taking place inside the electrocoat tank and take the necessary action to maintain the process quality and efficiency at a very high level.
