Rely on Us to Protect Your Investment
CerAnode Technologies is a division of APS Materials, Inc. (APS), a high-tech arc plasma spray coatings company. The present owners and operators of APS, originally part of Monsanto Corporation, incorporated APS as a private company in 1975. During our history, first as part of Monsanto Corporation and now as APS, we have applied thousands of different material systems using the plasma spray process.
CerAnode Technologies International manufactures a full line of Mixed Metal Oxide (MMO) Impressed Current Titanium Anodes for most every Cathodic Protection (CP) application. CerAnode™ anodes are distinctive with their unique arc-plasma sprayed surface architecture enhancement making them the most abrasion resistant MMO anode available. CerAnode™ Power Sources include Transformer Rectifiers (TR’s) and Solar Power Units. Other products include Reference Electrodes, Coupon Reference Probes and other corrosion sensor technology.
In 1984, by virtue of an exclusive technology transfer from the US Army Corps Construction Engineering Research Laboratory requiring the APS process, the CerAnode Technologies division was formed. The US Army Construction Research Laboratory (CERL) granted APS Materials, Inc. an exclusive license under the Davis Bacon Act for the technology it developed and patented.
The CerAnode Charter since its beginning has been to further research, develop and manufacture what is now the CerAnode version of MMO impressed current anodes. Today, CerAnode is recognized worldwide as a manufacturer of a complete line of state-of-the-art, high quality, MMO anodes and related products. CerAnode electrodes are used for cathodic protection, fossil fuel combustion optimization, chlorate and chlorine production, chemical conversion, plating, electrochemical remediation, sanitation, electro osmosis and electro-osmotic-pulse technology.
Other APS divisions use the arc plasma spray processing for a variety of industries including aerospace, biomedical, electronic, etc. APS-BioMedical applies porous titanium and calcium phosphate bioceramic coatings to bone implants used in patients suffering from osteoporosis. APS-Aerospace applies thermal barrier and wear resistant coatings to jet engine parts. APS-Electronics applies corrosion ceramics to chip manufacturing equipment. The CerAnode division uses arc plasma spray processing to manufacture abrasion resistant impressed current anodes by applying a very thin but powerful MMO ceramic coating to different titanium shapes. Made of the most inert materials known to man, CerAnode impressed current anodes are engineered to provide long term reliable service. Innovative cable-to-anode factory connections have virtually eliminated the traditional “weak link” of the Cathodic Protection Industry. The CerAnode cable-to-anode connection is engineered and manufactured under controlled conditions and quality control procedures. The anodes are durable, lightweight, ductile, and dimensionally stable. They are designed for ease of installation.
Cathodic Protection MMO Anode Wire (CPW)
CerAnode’s anode wire consists of an ultra thin layer of iridium + tantalum + titanium, mixed metal oxide, deposited onto either solid titanium core (STI version), a copper cored titanium interface (CTC version) or a copper cored niobium-titanium interface (CNC version). Available in nominal standard diameter sizes of 1/16” (1.5mm) OR 1/8” (3mm).
CerAnode CP anode wire is most often supplied in anode assembly configurations such as CerAnode’s Internal Potable Water Anodes, CerAnode’s Tank Anode for Water Storage Tanks, CerAnode’s Tank Bottom Anodes, CerAnode Linear Anodes, as well as for lock gates, intake screens, etc.
Cathodic Protection Cable – Halar® / High Molecular Weight Polyethylene (HMWPE)
Halar/HMWPE is a recommended anode lead wire cable choice for chloride and other harsh environments. Halar is the trade name for ethylene-chlorotrifluoroethylene (ECTFE). Since the electrochemical reaction at the anode in the presence of chlorides results in free chlorine gas generation causing rapid deterioration of most cable insulation, Halar®/HMWPE cable is preferred for use in harsh corrosive environments such as deep anode beds and other environments where chlorides and other harsh chemicals are present. It is also a good choice for oil environments and applications operating at elevated temperatures up to 150°C (302°F). It is the Halar insulation that provides resistance to these environments. The HMWPE jacket is designed to provide mechanical protection for the Halar during installation. The HMWPE jacket is not expected to survive these environments over extended periods.
Cathodic Protection Cable – Kynar® / High Molecular Weight Polyethylene (HMWPE)
Kynar/HMWPE is a recommended anode lead wire cable choice for chloride and other harsh environments. Kynar is the trade name for polyvinylidene fluoride (PVDF). Since the electrochemical reaction at the anode in the presence of chlorides results in free chlorine gas generation causing rapid deterioration of most cable insulation, Kynar®/HMWPE cable is preferred for use in harsh corrosive environments such as deep anode beds and other environments where chlorides and other harsh chemicals are present. It is also a good choice for oil environments and applications operating at elevated temperatures up to 110°C (230°F). It is the Kynar insulation that provides resistance to these environments. The HMWPE jacket is designed to provide mechanical protection for the Kynar during installation. The HMWPE jacket is not expected to survive these environments over extended periods.
CPR-E Tubular End Connect Anode Singles
The Econo-Tubular-Anode is a high quality but economical tubular anode ideal for applications where a single – one anode per cable – is preferred.

PiggyBack™ MMO Linear Anode Technology
CerAnode™ developed MMO linear anode technology and assigned the trademark PiggyBack™ in 1992. The technology is used around the world for applications including tank bottoms, underground vessels, bullet tanks and pipelines. The first PiggyBack™ installation was in 1993. Since that time continuous close-proximity anode-to-cathode applications have become a common design approach. In many applications this technology has significant advantages compared to traditional discrete anode arrangements. The technology provides optimized current distribution, optimized polarization characteristics, optimized groundbed resistance, optimized interference mitigation and better than ever power efficiencies.
Depending on the application the linear anode can be ordered with or without Coke Sock.
The sock material employed is GREEN in that it is environmentally safe. The anode’s sock decomposes leaving a conductive horizontal column at the position where it was buried allowing protection currents to pass freely to the structure. The MMO anode core is firmly positioned to protect the structure for many decades.
Since CerAnode manufactures the key components of the system, the product specification can easily be customized. Parameters such as design life, current rating, wire diameter, cable size and insulation type can be specified and manufactured quickly.
The Cross Piece Ventrolizer Bar is factory assembled on the anode end plugs. The MMO anode arrives onsite with its integral Ventrolizers, ready to tape or tie-wrap to an AllVent™ Pipe. This approach eliminates centralizer hassle in the field. The anode surface is not masked or damaged. It is rugged with no loose parts.
Solar Powered Cathodic Protection
CerAnode has the answer when your groundbed is remote and away from a power source. CerAnode can tailor a solar system to meet your application in your particular geographical location. We design and supply a system based on the amount of solar energy at site and your groundbed requirements that are specific to the application. The CerAnode standard controller will provide control of the groundbed current, voltage and potential.
