Proportional Dispenser DOSAPHOS 250 - 1/2"; SET - action – SALE GEL.KIT DOSAPHOS 250

Product detailed description

The IVAR DOSAPHOS 250 is commonly used in residential and commercial hot water systems where limescale prevention is essential. It is installed in systems where water hardness is moderate and the risk of scale formation is high. The dispenser ensures a proportional dose of anti-scale agent is added to the water flow, maintaining system efficiency and reducing maintenance requirements. It is particularly suited for systems where water hardness does not exceed 2.0 mmol/l, as higher hardness levels may affect performance. The dispenser is designed for integration into hot water lines and is not suitable for cold water applications.

Technical parameters

Material	head - nickel-plated brass
Operating temperature	+5 °C
Nominal pressure	PN 6
EAN	8018244047806
Weight	1.296 kg
Code	104.520.00
Brand	IVAR

The operating temperature of +5 °C indicates that the dispenser is suitable for use in environments where the water temperature does not drop below this threshold. The nominal pressure rating of PN 6 means the dispenser is designed for systems operating at moderate pressures. The material composition—nickel-plated brass for the head and SAN for the tank—ensures resistance to corrosion and chemical exposure, making it suitable for long-term use in water treatment systems.

Installation and connection

The IVAR DOSAPHOS 250 is installed in the hot water line using a 1/2 inch connection. The installer should ensure that the system water hardness does not exceed 2.0 mmol/l, as the dispenser is not designed for high-hardness water. The dispenser should be mounted in a location that allows easy access for refilling and inspection. Common installation mistakes include incorrect orientation of the dispenser or failure to check the water hardness before installation. It is important to verify that the system flow rate does not exceed 2.0 m³/hr to ensure proper operation of the dispenser.

Compatibility and accessories

The dispenser is compatible with hot water systems where limescale prevention is required. The kit includes one GEL.DOSAPHOS 250 dispenser and eight GEL.GELPHOS RAPID replacement cartridges. These cartridges are designed for use with the dispenser and provide anti-scale treatment for approximately 15 m³ of water. No additional accessories are required for installation, but the dispenser should be used in conjunction with a water hardness test to ensure it is suitable for the system.

Technical background for designers

The IVAR DOSAPHOS 250 operates by releasing a proportional amount of anti-scale agent into the water flow, based on the volume of water passing through the system. The nickel-plated brass head and SAN tank provide resistance to corrosion and chemical degradation, ensuring long-term reliability. The dispenser is designed for integration into hot water systems and should not be used in cold water applications. The effectiveness of the dispenser depends on the water hardness and flow rate, with higher hardness levels reducing the efficiency of the treatment. The system should be sized to ensure that the dispenser can operate within its maximum flow rate of 2.0 m³/hr.

Service and operation

The dispenser requires periodic refilling of the anti-scale agent, with each cartridge providing treatment for approximately 15 m³ of water. The refilling process is straightforward and involves replacing the spent cartridge with a new one. The dispenser should be inspected regularly to ensure that it is operating correctly and that the water hardness remains within the recommended range. No specific service intervals are provided, but the system should be monitored for signs of reduced performance or blockage.

Frequently asked questions
