Spare cartridge - for GEL.DOSAPHOS 250 - 8x cartridge GEL.GELPHOS RAPID

Product detailed description

Replacement cartridges are essential for maintaining the efficiency of water softening and conditioning systems in residential and commercial buildings. Installers working with proportional dosing systems often encounter the need to replace spent cartridges in systems designed to reduce limescale formation. These systems are typically used in domestic hot water circuits where water hardness is moderate and controlled dosing is required to prevent scaling in pipes and appliances. The IVAR GEL.DOSAPHOS 250 system is commonly found in installations where water hardness is within recommended limits and where a compact, proportional dosing solution is required.

The GEL.DOSAPHOS 250 system is designed for integration into hot water supply lines, where it delivers a controlled dose of water treatment chemicals in proportion to the flow rate. This helps to reduce the risk of scale formation in boilers, heat exchangers, and other components. The system is not suitable for high-hardness water conditions and requires regular cartridge replacement to maintain performance.

Technical parameters

Installation and connection

Installation of the replacement cartridge involves removing the spent unit and inserting the new one into the housing. The system uses a proportional dosing mechanism that requires no electrical connection. The cartridge is connected via standard threaded fittings, and it is important to ensure that the system is isolated and drained before replacement. Common installation errors include incorrect orientation of the cartridge and failure to check the integrity of the housing seal. A visual inspection of the housing for wear or damage is recommended before fitting a new cartridge.

Compatibility and accessories

This cartridge is specifically designed for use with the GEL.DOSAPHOS 250 and GEL.GELPHOS RAPID systems. It is not compatible with other IVAR dosing systems that require different chemical formulations or dosing rates. No additional accessories are required for installation, but it is important to ensure that the system housing is in good condition and that the inlet and outlet connections are secure. The pack contains 8 replacement cartridges, which is sufficient for multiple replacements depending on usage.

Technical background for designers

The cartridge operates on a proportional dosing principle, where the amount of chemical released is directly related to the flow rate of the water. The housing is made of SAN (styrene acrylonitrile), a durable and chemically resistant material suitable for water treatment applications. The cartridge head is made of nickel-plated brass, which provides corrosion resistance and mechanical strength. The system is designed for integration into hot water circuits and requires no external power supply. The service life of the cartridge is influenced by the chemical concentration, water hardness, and flow conditions.

Service and operation

Regular replacement of the cartridge is necessary to maintain system performance. The recommended replacement interval is based on the volume of water treated, with the cartridge providing approximately 15 m³ of treatment capacity. During operation, it is important to monitor the system for signs of reduced dosing efficiency, such as increased scaling or reduced water quality. No specific service intervals are provided in the brief, but the system should be inspected periodically to ensure that the housing and connections are intact.

Frequently asked questions

Can the cartridge be used with water temperatures above 40 °C?
No, the cartridge is rated for operation between +5 °C and +40 °C. Use beyond this range may affect performance and integrity.

Is the cartridge suitable for high-hardness water?
No, the system is not recommended for water with hardness exceeding 2.0 mmol/l. High-hardness water may require a different treatment system.

How many replacements does the pack contain?
The pack includes 8 replacement cartridges, which is sufficient for multiple replacements depending on usage.

Can the cartridge be used in cold water applications?
Yes, the cartridge is suitable for use in warm water applications and can also be used in cold water systems within the specified temperature range.
