Refill - for proportional dosing machine DOSAPHOS - 10kg GEL.GELPHOS P-NAPLN

Product detailed description

Proportional dosing systems are essential in commercial and industrial heating installations where water quality can affect equipment performance and longevity. Installers working in multi-building complexes, district heating systems, or large-scale HVAC environments regularly encounter issues such as scaling and corrosion in boilers, heat exchangers, and pipework. These problems can lead to reduced efficiency, increased maintenance costs, and premature component failure. To counter these effects, a chemical dosing system is integrated into the water supply line, ensuring continuous and accurate treatment of the circulating water.

The IVAR DOSAPHOS system is specifically designed for the controlled dosing of water treatment chemicals in closed-loop systems. It is commonly used in conjunction with central heating systems, where the risk of limescale and corrosion is high due to elevated temperatures and prolonged water circulation. The refill unit provides a ready-to-use powder formulation that is mixed on-site to create a stable, homogeneous solution. This solution is then proportionally dosed into the system based on the flow rate, ensuring consistent protection of all system components.

The refill contains 1kg of dry chemical formulation in a 10kg packaging. This quantity is sufficient to treat between 100 and 120 cubic metres of water, depending on the hardness and impurity levels. The refill is compatible with the DOSAPHOS dosing machine and must be mixed according to the instructions provided. The dosing machine is pre-calibrated for proportional dispensing, so the installer must ensure the correct water level and powder amount are added during the initial preparation.

Installation and connection

To prepare the dosing solution, the doser container must first be filled with water up to the H2O mark. The GELPHOS P powder is then added until the MAX or PRODUCT mark is reached. The mixture should be stirred thoroughly and allowed to rest for 20–25 minutes before use. The dosing machine must be installed in a location accessible for refills and maintenance, and the dosing line must be connected to the system’s water supply line using appropriate fittings and valves. During installation, it is important to verify that the doser is correctly aligned with the flow direction and that all connections are leak-free. A common mistake is incorrect mixing ratios, which can lead to either under-dosing or excessive chemical usage.

Compatibility and accessories

This refill is specifically designed for the DOSAPHOS dosing machine and cannot be used with other models without modification. No additional accessories are required for basic operation, but the doser must be installed with a suitable mounting bracket and connected to a stable water supply. There are no related products listed for this refill.

Technical background for designers

The GELPHOS P powder is a chemical formulation designed to inhibit scale formation and reduce corrosion in metal components. It works by binding to calcium and magnesium ions in the water, preventing them from forming deposits on surfaces. The powder is hygroscopic and must be stored in a dry environment to prevent clumping. Once mixed with water, the solution remains stable for a limited period and must be used within the recommended time frame. The dosing machine operates on a volumetric principle, where the amount of chemical dispensed is proportional to the volume of water passing through the system. The effectiveness of the treatment depends on the correct mixing ratio, the stability of the solution, and the integrity of the dosing line.

Service and operation

Regular inspection of the dosing machine is necessary to ensure it is functioning correctly. The doser container should be checked for residue buildup and cleaned as needed. The mixing chamber must remain free of blockages to allow for proper dispersion of the solution. The solution should be prepared fresh for each refill cycle and not reused after the cooling and resting period. There are no specific service intervals provided in the brief, but the system should be monitored for signs of reduced dosing accuracy or clogging of the dosing line.

Frequently asked questions

Can the GELPHOS P powder be mixed with other water treatment chemicals?
No, the powder must be used alone in the DOSAPHOS doser. Mixing with other substances could affect the stability of the solution and reduce its effectiveness.

How long does the prepared solution remain usable?
The solution should be used within 20–25 minutes after mixing. It must be homogenized and cooled before being introduced into the system.

Is the dosing machine compatible with other refill formulations?
No, the DOSAPHOS machine is designed specifically for the GELPHOS P powder refill. Using other formulations could damage the doser or affect the accuracy of the dosage.

What should be done if the doser fails to dispense the correct amount?
Check the water level in the container and the presence of the powder up to the MAX mark. Ensure the doser is properly connected to the system and that there are no blockages in the dosing line.
