Hypochlorite generators of superior quality.

Our Electrolytic Cell

Overview

Electrichlor electrolytic cells are highly efficient due to the patented monopolar, multi‐pass, tubular configuration that allows a progressively longer residence time for the complete adsorption and conversion of Cl2 into hypochlorite in the outgoing solution (see Figure 1). This additional conversion of Cl2 into hypochlorite is specifically enabled due to the decreasing linear velocity as the seawater flows through the cell, significantly increasing the productive capacity without requiring additional electrical power. The cell electrodes have a low, uniform current density over the entire anode/cathode surface which further enhances the overall efficiency of the electrolytic cell, promoting a long‐anode life. Electrichlor’s electrolytic cells have a long operational life that in many applications have exceeded ten (10) years of near continuous operation.

The Electrichlor electrolytic cell is characterized as an open cell and has no specific requirement for upstream water filtration beyond that performed by a strainer. The open, membraneless, cell design requires minimal periodic maintenance and is not susceptible to obstruction by foreign objects under approximately 3 to 5 mm (0.12 to 0.20 in) in diameter, depending on the cell model employed. Electrichlor electrolytic cells are proudly made in the USA. The anode and cathode assembly can be separated for inspection using standard shop tools. An entire cell assembly can be exchanged in the field.

Materials 

Electrichlor electrolytic cells are all titanium with a mixed metal oxide (MMO) coating to create dimensionally stable anodes. All wetted parts of the cell are titanium, MMO coated titanium, ultra‐high molecular weight polyethylene, CPVC, and EPDM. The cell assembly is joined using 316SS fasteners and Nylon insulators.

Efficiency

Electrichlor electrolytic cells typically show an electrical conversion efficiency of 4.5 to 6.0 kW per kg per hour of chlorine as sodium hypochlorite/sodium hypobromite. Over time the accumulation of calcium and magnesium salts, referred to as inorganic scaling, on the electrodes reduces the electrical conversion efficiency. After a periodic interval, as the conversion efficiency of the electrolytic cell decreases, removal of accumulated inorganic scale is required to restore operational efficiency. Removal of this inorganic scale is performed using a routine low pH wash cycle.
