Cylindrical Aluminum Heat Treater Anode

Aluminum heater treater anode is a sacrificial anode used for excellent corrosion protection in a variety of industries. It is typically applied in heater treaters, heat exchangers, salt water storage tanks, oilfield tanks, skimmers, oil-separation vessels, pressure vessels and other production vessels.

This cylindrical shaped aluminum anode is a 3″ diameter cast anode with a 3/4″ diameter all-thread steel rod core. It is perfectly suitable for any type of structure requiring a compact solution in relatively higher temperature or lower chloride saltwater environments.

Mounted in fiberglass “Red-Cap” or “Blue-Cap”, this cylindrical aluminum anode can be easily installed and replaced in a standard 4-inch (100 mm) schedule 40 or schedule 80 pipe nipple with grooved coupling.

Quality Substrate Material
Casted from high-voltage and high-potential alloy, our aluminum anode is designed to meet the standard GS EP COR 201, containing nominal amounts of indium, zinc, and silicon. It has a proven track record for delivering superior cathodic protection in highly corrosive saltwater/brines with elevated temperatures.

Low Driving Voltage
This aluminium condenser anode provides a stable performance in seawater and electrolytes containing chloride ions as its operating potential is kept between -1.05 to -1.10 volts relative to saturated calomel electrode(SCE).

Technical Measurement Performance
Open Circuit Voltage (-V) 1.10 min.
Closed Circuit Voltage (-V) 1.05 min.
Current Capacity 1135 A.h/lbs (2500 A.h/kg)
Current Efficiency 90% min.
Consumption Rate 7.6 lbs/A·y (3.4 kg/A·y)

Two Mounting Head Options
The heat treater anode can be assembled with high compression molded fiberglass anode mount caps (blue or red) and attached with lead wires for quick installation. The head cap is designed with four integral ribs that insure optimal skid resistance, proper alignment and superior in-flow anode stability. The red cap can be installed in standard 4″ SCH 40 fittings with grooved couplings. The blue cap can be used for mounting in standard 4″ SCH 80 fittings with grooved Victaulic® couplings.
