The CPR™ and CPR-S™ are mixed precious metal oxide impressed current anodes specifically designed for the demands of deep anode ground beds. They are also an excellent choice for shallow beds, horizontal beds, offshore and other CP applications. By means of a very special cable-to-anode connection, CerAnode™ has uniquely combined the features of an enhanced version of a well established precious metal oxide anode technology with well established CP cable materials such as HMWPE, Dual Extruded cables with Halar®, Kynar®, etc..
CPR™---ONE ANODE PER CABLE. The CPR™ consists of one anode power tube at the end of a standard economical 8 AWG HMWPE or Dual Extruded CP cable. The CPR™ is used where anodes with individual leads are desired for maximum anode bed system integrity. This traditional ground bed approach allows individual anode current and depth control.
CPR-S™---MULTIPLE ANODES PER CABLE. The CPR-S™ is a string version of the CPR™ consisting of a number of anode power tubes on a single HMWPE or Dual Extruded cable. The CPR-S™ has a very unique power feed-through arrangement for feeding power from one anode to the next on the string. This provides anode string burnout protection. The end result is anode string integrity never before realized!
The CPR™ and CPR-S™ anode design not only makes cost effective installation possible, but has added a new magnitude of anode reliability. A truly Hi Tech CP Anode has finally surfaced. It is definitely the anode of the Future with a Track Record.
| UNIQUE FEATURES |
1) HIGH POWERED ACTIVATED TITANIUM ANODE. CerAnode's very thin anode coating in combination with its ductile titanium substrate is extremely durable. The particular mixed metal oxide ceramic is custom formulated for each CPR™ and CPR-S™ and is tested at extremely high current densities to insure consistent product quality. It consists of precious metal/metal oxides in sufficient quantities and ratios to provide a life expectancy beyond its cataloged value. This provides the conservatism in anode design needed to assure a long life even in harsh environments such as deep anode beds and offshore applications. Since this ceramic material will support the evolution of both oxygen and chlorine, it is the choice for fresh water, sea water, mud, brackish water and coke/soil environments.
2) STANDARD HMWPE OR DUAL EXTRUDED CABLE. The CPR™ and CPR-S™ use cable that has been an industry standard for many decades, a proven reliable choice. The cable choices have withstood the test of time. HMWPE is the most popular but Kynar®/HMWPE or Halar®/HMWPE are available for more demanding applications where chlorides or other harsh environments are involved. These cables are also among the lowest priced cables available making them economically attractive. Other cable choices such as EPR/CSPE are also available for some applications.
3) ANODE STRING BURNOUT PROTECTION. The electrical feed-through connection between the tubular anode and the cable is unique. No copper or other metal exists directly under the exposed Power-Rod tubular anode! Therefore, (a) if any one anode tube on the anode string should ever receive a puncture due to arcing or a microscopic flaw in the titanium tube, it will continue to operate since there is no copper under the tube wall. And, (b) if, by reason of the characteristics of a particular deep anode bed stratum, the anode tube at that stratum should ever become exhausted prematurely due to unanticipated excessive current, the remainder of the anode string will continue to operate. Why? Because the electrical current passing through the center of any anode tube on the anode string to the next anode tube on that string, is not dependent on the condition or presence of any other anode tube on that string!
4) MOISTURE PROOF CORROSION RESISTANT CONNECTION. The CerAnode MultiSeal™, consisting of 7 distinct seals per single anode tube (14 per string tube) assures a moisture proof connection and excellent resistance against acids & chlorine gas sometimes associated with a deep anode environment. The string also has inherent "water block" integrity at every anode tube. This means that the CP cable jacket and tubes cannot act as one continuous siphon from the bottom of a deep anode bed to the surface.
5) ULTRA LOW ELECTRICAL CONNECTION RESISTANCE. The special TIG Weld-Swage has resulted in an ultra low resistance electrical connection. The cable-to-titanium tube connection resistance us ultra-low having a mean copper-to-titanim resistance of <50 micro-ohms as measured with a 4-wire Kelvin type resistance bridge capable of resolving 5x10-5 ohms.
6) MAXIMUM MECHANICAL STRENGTH. The cable-to-anode connection is achieved by means of a proprietary copper to titanium valve metal swage process. The connection is so strong that the cable breaks before the connection.
7) CerAnode 7 YEAR ANODE WARRANTY. CerAnode Technologies of APS-Materials, Inc. will give you a new anode if our anode should stop functioning within 7 years when installed and operated according to the anode's instructions. This is a North American warranty but is otherwise negotiable.

| GENERAL INFORMATION |
Single or Multiple Power-Rod tubes may be specified per anode cable (string) to obtain total anode bed current required. The environment (coke/soil or sea water) and cable (gage size) resistance must be considered when specifying the number of anodes/cables and their spacing. This is for consideration of not only the cable's current capacity but also the cable-to-coke/earth and anode-to-coke-to-earth attenuation. When in doubt, consult CerAnode.
Use a 20 mil (0.5 mm) thick fluoro-insulation for deep anode beds where chlorine gas may be generated or where other aggressive chemicals might be present. For open hole applications specify a 40 mil (1mm) fluoropolymer. CerAnode will supply the most available and ecconomical fluoropolymer (Halar, Tefzel of Kynar) unless otherwise specified. EPR/CSPE and HMWPE are not acceptable as a primary insulation in groundbeds where chlorine is present. Chlorine gas FluoroShieldtm can be used with EPR/CSPE & HMWPE in sea water applications where the chloride gas is washed away except for the area immediate to the anode. All CerAnode Tubular singles and strings are manufactured with FluoroShields but these shields are not designed to replace the need for fluoropolymer cable in deep anode applications.
The CPR and the CPR-S are easy to install but must be installed by qualified personnel. It is important that a high quality Calcined Fluid Petroleum Coke Backfill (low resistivity--98-99% carbon, high density and small particle size) be used. [Design suggestions: Conservative current densities at the coke-to-earth interface should be <0.15 Amp/ft², preferably lower. Conservative coke column attenuation between anodes should also be considered in light of the coke to earth interface current density.] Vent pipes must be used in deep and shallow anode beds and arranged 1" from anode. To prevent the entry of silt, sediment or fine coke particles the slots should be no larger than 0.006"-0.008". Centralizers must be used in groundbeds to assure proper current distribution from the anode.

The Econo-Tubular-Anode is a high quality but economical tubular anode ideal for applications where a SINGLE - one anode per cable – is preferred. It is designed for the demands of deep anode beds, shallow beds and the earth’s natural waters. It is specially designed end connection allows for quick custom cable lengths. Light weight construction provides ease of handling and economy of shipping.
This anode is manufactured using the same special arc-plasma spray processing developed by CerAnode in the mid 80’s. The connection is of the highest quality electrically and environmentally having a copper-to-titanium resistance of <100 micro ohms with an environmental MultiSeal™ encapsulation fully resistant to nascent chlorine gas. It also features a FluoroShieldtm cable guard. The anode’s catalytic EMMO coating is tightly sintered to its titanium substrate resulting in a truly unique surface architecture providing an abrasion resistant surface protecting it from injury during installation. It is “one-of-a-kind” among the many MMO technologies available in the marketplace today. It features iridium as its primary catalyst which the Chemistry and Physics Handbook classifies as the most inert material known to man. The proprietary nature of the catalyst mixture and deposition process results in a very special ceramic anode product.
