Refill - for proportional dispenser DOSAPHOS - 1kg GEL.GELPHOS P-NAPLN

Product detailed description

Proportional dispensers are commonly used in commercial and residential hot water systems to manage water hardness and prevent limescale buildup. Installers working on systems with moderate hardness levels can benefit from these units, which provide controlled dosing of anti-scaling agents. The IVAR DOSAPHOS system is designed for integration into heating and plumbing systems where water hardness is a concern but not extreme. It is typically installed in pre-treatment stages before the main heating or storage unit to ensure consistent water quality.

These systems are particularly useful in hotels, apartment blocks, and industrial facilities where hot water is supplied to multiple points. The dispenser ensures that the anti-scaling agent is dosed in proportion to the water flow, maintaining efficiency without overuse. The system is not intended for use in areas with high hardness levels, where alternative water treatment methods may be more appropriate.

Technical parameters

Material	nickel-plated brass head
Operating temperature	+5 °C
Package includes	0.5 kg GEL.GELPHOS P media
Nominal pressure	PN 6
EAN	8018244002904
Weight	1.028 kg
Code	107.010.50
Brand	IVAR

The nominal pressure rating of PN 6 indicates the system is suitable for low-pressure applications, typical in domestic and light commercial settings. The operating temperature of +5 °C is the minimum required for the media to function correctly. The dispenser is sized for a maximum flow rate of 5.8 m³/h, which determines the system's capacity and the frequency of refill requirements. These parameters are essential for ensuring the dispenser is correctly matched to the system's hydraulic conditions.

Installation and connection

The dispenser should be installed in a location that allows easy access for maintenance and refill. It is typically connected to the hot water supply line using standard pipe fittings. The connection size and thread type must be verified to match the existing system. During installation, it is important to ensure that the flow direction is correct and that the unit is securely mounted. Common mistakes include incorrect orientation of the dispenser head and failure to check for leaks after installation. A pressure test should be performed to confirm the system is sealed correctly.

Compatibility and accessories

This refill is specifically designed for use with the GEL.DOSAPHOS 600 and GEL.DOSAPHOS 700 models. It is not compatible with other dispenser types or with systems requiring high hardness treatment. No additional accessories are required for operation, as the dispenser is self-contained. The refill unit includes the necessary media and housing for immediate use. When replacing the refill, the old media should be removed and the housing inspected for wear or blockage.

Technical background for designers

The dispenser operates by releasing an anti-scaling agent in proportion to the water flow. The media, GEL.GELPHOS P, is a solid formulation that dissolves gradually in the water stream. The dispenser head is made of nickel-plated brass, which provides resistance to corrosion and ensures long-term durability. The media is contained in a SAN container, which is chemically inert and compatible with the active ingredients. The system is integrated into the water circuit upstream of the heating element to ensure even distribution of the treatment agent. The efficiency of the system is influenced by the water hardness, flow rate, and the condition of the media. Regular monitoring of the water quality is recommended to ensure optimal performance.

Service and operation

The refill media should be replaced when the dosage efficiency begins to decline, typically after 100 to 120 m³ of treated water. There are no scheduled service intervals specified for this model. During replacement, the old media should be removed and the housing cleaned if necessary. The new refill is inserted and secured in place. It is important to ensure that the dispenser is fully sealed after installation to prevent leakage. The system does not require electrical power and is entirely mechanical in operation.

Frequently asked questions

Can the refill be used with cold water systems?
No, this model is designed for use with hot water only. The media requires a minimum temperature of +5 °C to function correctly.

Is the dispenser suitable for water with hardness above 2.0 mmol/l?
No, the system is not recommended for water with hardness exceeding 2.0 mmol/l. Alternative treatment methods should be considered for such conditions.

How often should the refill be replaced?
The refill should be replaced after approximately 100 to 120 m³ of treated water, depending on the flow rate and water hardness.

Can the dispenser be installed in a vertical position?
Yes, the dispenser can be installed in either horizontal or vertical orientation, provided the flow direction is maintained and the unit is securely mounted.
