TubeCell Anode Cell

The Electrocoating Process

Anode Cells are an essential component of most Cathodic electrocoat painting systems.  The Cells serve as the positive electrode in the painting process where  the material being painted is the cathode, or negative electrode.  The Cells also remove excess acid from the paint, which is essential to maintaining paint bath chemistry.  Cathode  Cells for Anodic paint lines are also available.

The TubeCell
Anode Cell

TubeCell™ Anode Cells combine maximum anode cell operating efficiency with features that provide ease of installation, operation and maintenance.  Each cell is comprised of an Anode Tube, which is the positive electrode in the painting process, and a larger, concentric Membrane Tube, which, provides selective removal of the paint acid and other anions from the paint bath.

Installation of TubeCell™ Anode Cells is easy.  The Cells are not heavy, weighing only 3-lbs per foot of effective length.  One person can install or remove even very long Cells without difficulty.  Cell spacing can easily be optimized along the side of the tank to balance current draw and avoid piping interferences. TubeCell™ Anode Cells can replace box type cells.

Pressurized Cells
The standard Cell is not sealed at the top and relies on gravity flow for anolyte return.  The Pressurized Cell is utilized where Cells must be below the tank rim or  completely submerged in the the paint. The Cell features a bulkhead nut that can be tightened and loosened by hand, and there are no tubing or bolted electrical connections inside the Cell

Anode Materials

Schedule 40 316L stainless steel is standard.  Heavier gauges of stainless steel and ruthenium oxide coated titanium and  other inert materials are also available.
