Protective anode made of magnesium alloy with zinc plating. plug - 6/4 "x400mm; dia. 32mm; 800-2000l IVAR.AM4

Product detailed description

Metallic corrosion is a critical concern in domestic hot water systems, particularly in storage tanks where water remains stationary for extended periods. Corrosion leads to tank degradation, reduced efficiency and eventual system failure. This protective anode is specifically engineered for installation in cylindrical water heating units with internal diameters matching standard domestic applications. It is commonly found in residential and commercial buildings where water hardness levels are moderate and the system operates within standard temperature ranges. The plug-in design allows quick replacement during service without requiring complete tank dismantling.

The anode is typically installed in conjunction with electronic control units that monitor and regulate the sacrificial protection process. It integrates with conventional electric water heaters and thermal storage systems, ensuring long-term reliability through continuous electrochemical activity. Proper installation ensures even distribution of protective currents across the internal surfaces of the tank, preventing localized pitting and structural weakening.

Technical parameters

Installation and connection

Installation requires access to the tank interior via a dedicated port or removable panel. The anode is inserted until the threaded portion engages with the internal mounting point. A zinc-plated connector ensures stable electrical contact with the tank body. The plug-in mechanism eliminates the need for additional wiring or soldering. Installers should verify that the anode is fully seated and that the electrical connection is uninterrupted. Common errors include incomplete insertion, which reduces protection effectiveness, or incorrect polarity when paired with control units.

Compatibility and accessories

This anode is designed for use with IVAR electronic control units and compatible sacrificial anode monitoring systems. For full functionality, an electronic controller must be installed to manage the electrochemical process and alert users to anode degradation. No additional mechanical components are required due to the self-contained plug-in design. Installers should ensure that the tank material is conductive enough to support the electrochemical process and that all electrical connections are watertight.

Technical background for designers

The anode operates on the principle of galvanic corrosion, where the magnesium alloy sacrifices itself to protect the steel tank walls. The zinc plating enhances initial conductivity and reduces the risk of early failure due to oxidation. The alloy composition determines the rate of consumption and overall service life under normal operating conditions. Integration into the system depends on the electrical continuity between the anode, tank shell and ground connection. System variables such as water pH, mineral content and temperature fluctuations affect the rate of anode degradation and the efficiency of the protective layer formed on metal surfaces.

Service and operation

Periodic inspection is essential to confirm continued electrical contact and absence of physical damage. Visual signs of degradation include visible wear on the anode surface and reduced effectiveness in preventing tank corrosion. Replacements should be performed before the anode is completely consumed to maintain protection. No active maintenance is required beyond visual checks and replacement when necessary.

Frequently asked questions

Can this anode be used with non-metallic water heater tanks?
No. The anode requires a conductive tank surface to create the necessary electrochemical reaction. Non-metallic tanks are incompatible with sacrificial anode technology.

Is it possible to replace the anode without draining the tank?
Yes. The plug-in design allows replacement without emptying the tank, provided access to the installation port is available and the tank is switched off.

Does the anode require a separate power supply for operation?
No. The protection process is passive and relies solely on the electrochemical properties of the magnesium alloy and the tank material.

Can the anode be used in combination with electronic monitoring systems?
Yes. The design supports integration with control units that monitor the condition of the anode and provide early warning of depletion.
