Proportional dispenser IVAR.POLIFEMO EXTRA - 1/2"; 16 balls of filling - action IVAR.POLIFEMO EXTRA

Product detailed description

This proportional polyphosphate dispenser is typically installed in residential and commercial heating systems to manage water quality and prevent mineral buildup. It is commonly used in conjunction with boilers, heat pumps, washing machines and dishwashers. The device ensures a consistent chemical dosage proportional to the water flow, helping to extend the lifespan of system components and improve overall efficiency.

Its compact design allows for flexible mounting in tight spaces, and the transparent tank with an orange float provides a visual indication of the remaining fill volume. The dispenser is suitable for systems where water hardness and corrosion risk require periodic chemical treatment. It is particularly useful in installations where water quality varies seasonally or regionally.

Technical parameters

Material	Head: chrome-plated brass
Operating temperature	+5 °C
Nominal pressure	PN 10
Code	520211
Brand	IVAR

The dispenser is rated for a minimum operating temperature of +5°C and a nominal pressure of PN 10. These parameters are critical for ensuring compatibility with standard domestic and industrial water supply systems. The chromed brass head offers resistance to corrosion and mechanical wear, while the GRILAMID tank is lightweight and durable. The maximum flow rate and refill capacity should be considered during system sizing to ensure continuous operation between refills.Installation and connection The IVAR POLIFEMO EXTRA is connected to the water supply line using a 1/2 inch threaded connection. It is recommended to install the unit vertically, although four mounting orientations are possible. Before installation, ensure the water supply is isolated and the system is depressurised. Check for correct thread engagement and apply sealing compound if necessary. A common mistake is incorrect orientation, which can affect the accuracy of the dosing mechanism. After fitting, verify the float movement and ensure the filter is intact to prevent particulate ingress.Compatibility and accessories This dispenser is compatible with a wide range of heating and water systems, including those with heat pumps, combi boilers and domestic appliances. For installations requiring shut-off functionality, a separate valve and bypass may be required. The device includes a built-in filter for mechanical impurities larger than 100 μm, eliminating the need for additional filtration in most cases. No specific accessories are listed for this model.Technical background for designers The IVAR POLIFEMO EXTRA operates using a proportional dosing mechanism that delivers polyphosphate solution in direct relation to the water flow rate. This ensures that the chemical concentration remains consistent regardless of variations in demand. The chromed brass head provides durability in wet environments, while the GRILAMID tank is resistant to UV light and chemical degradation. The device integrates easily into existing systems and does not require external power. Long-term performance depends on regular refilling and the absence of particulate matter in the feed water.Service and operation The transparent tank allows for easy monitoring of the fill level. Refilling is required when the orange float drops below the visible mark. There are no specified service intervals for this model, but the tank should be inspected periodically for blockages or wear. If the float becomes stuck or the filter is clogged, disassemble and clean the affected parts. Ensure the tank is fully sealed after refilling to prevent leakage and contamination.

Frequently asked questions

Can the IVAR POLIFEMO EXTRA be installed horizontally?
Yes, the dispenser supports four installation positions, including horizontal. However, vertical installation is recommended for optimal dosing accuracy.

What is the function of the orange float in the tank?
The orange float indicates the remaining volume of polyphosphate solution in the tank. When it drops below the visible mark, the tank needs to be refilled.

Does the dispenser include a shut-off valve?
No, the standard model does not include a shut-off valve. A separate valve and bypass may be required for installations needing isolation capability.

What kind of impurities does the built-in filter remove?
The filter removes mechanical impurities larger than 100 μm (0.1 mm), such as sand, rust and scale particles, preventing them from entering the dosing mechanism.
