Cathode and Voltage Reduction Coatings Improve Performance and Save Energy Costs

ECC-11™ Cathode Coating - The chlor-alkali industries leading cathode coating available for Chlorine Membrane cells. This platinum based electro catalyst delivers the lowest hydrogen over-potential for maximum electrical savings. ECC-11™ Cathode Coating also provides excellent wear resistance through a permanent coating which causes no caustic contamination as compared to competitive coatings.

ECC-11™ Cathode coating can be cleaned and rejuvenated (unlike competitive coatings) and once iron deposits are removed and voltage performance is restored. ECC-11™ can be applied over a variety of substrates including mesh, louvers, sheet, punched plate and screen. Usage does require cell disassembly.

VRS™
VRS™ is an on-site, in-situ applied cathode coating for chlorine membrane cells

Cell disassembly not required
Spare cathodes not required
Cathode shipment not required

VRS™ is comprised of noble metal salts and is supplied in ready-to-use 1 liter bottles. When added to the caustic compartment during cell operation VRS™ Instantaneously lowers the cell voltage by lowering the hydrogen over-potential. VRS™ can be applied over coated, fouled or uncoated cathode substrates. VRS™ can be used in all technology suppliers cells

ELTECH, Asahi Kasei, UHDE, CEC, DeNora, Lurgi, etc
Monopolar, BiPolar, Dense Packs

VRS™ will deliver 200-300 mV savings vs. bare nickel cathodes.

Test conditions: 4 kA/m2, 90 degrees C, 32 wt% NaOH, 200 gpl NaCl

VRS™ can restore low voltage performance lost due to catholyte impurities such as Iron, Nickel and Mercury.

VRS™ will not contaminate the caustic product. Procedures are available for VRS™ usage in single electrolyzers or entire circuits. VRS™ economic payback is typically about 3 months based on power savings alone. VRS™ can be used to increase manufacturing rates when rectifier capacity is limited.
