Caleffi DIRTMAG® 1"

Product detailed description

The CALEFFI DIRTMAG® 1' is designed for installation in heating, plumbing and irrigation systems to separate solid particles and ferromagnetic impurities from the fluid flow. It is commonly used in residential, commercial and industrial buildings to maintain system efficiency and protect downstream components such as pumps, valves and heat exchangers. Installers typically integrate it into closed-loop systems, open-loop water supply lines or irrigation circuits to ensure clean operation. The unit is suitable for both vertical and horizontal pipe orientations, offering flexibility during installation.

Its compact design allows for integration in tight spaces, while the internal threading ensures compatibility with standard pipe connections. The drain port with hose attachment enables regular removal of collected debris without system shutdown. The operating temperature range of 0 to 90 °C makes it suitable for a wide range of applications, including hot water systems and chilled water circuits.

The maximum operating pressure of 3 bar is important for determining system compatibility and ensuring safe operation under normal working conditions. The temperature range of 0–90 °C allows the device to function effectively in both cold and hot water systems. These parameters are essential for correct sizing and selection to match the system’s hydraulic and thermal requirements.

Installation and connection

The DIRTMAG® 1' is installed using internal threading, which requires matching external threads on the connecting pipes. The unit is typically placed upstream of sensitive components such as circulation pumps or heat emitters to intercept particulate matter before it causes damage. During installation, it is important to ensure that the unit is oriented correctly according to the flow direction indicated on the body. A common mistake is incorrect orientation, which can reduce separation efficiency. Installers should also ensure that the drain port is accessible for periodic cleaning. The hose connection should be secured properly to avoid leaks. Before commissioning, the system should be flushed to remove any residual debris that might have entered during installation. A pressure test at up to 3 bar is recommended to verify the integrity of all connections.

Compatibility and accessories

The DIRTMAG® 1' is compatible with standard plumbing and heating systems that use 1-inch pipe connections with internal threading. It works well with other filtration components such as strainers and sediment traps, depending on the level of contamination in the system. For optimal performance, it is recommended to pair it with a pressure gauge and a shut-off valve for isolation during maintenance. No additional accessories are required for basic installation, but a suitable drain hose may be needed for the cleaning port.

Technical background for designers

The DIRTMAG® 1' operates by combining mechanical sedimentation with magnetic separation. As the fluid flows through the chamber, heavier particles settle at the bottom due to gravity, while ferromagnetic particles are attracted to the internal magnet. The body is made of technopolymer, which offers resistance to corrosion and chemical degradation, making it suitable for long-term use in a variety of fluids. The internal threading ensures a secure connection, reducing the risk of leakage. The unit integrates into both closed and open systems, provided the operating conditions remain within the specified pressure and temperature limits. Its efficiency is influenced by flow velocity, particle size and the presence of magnetic materials in the fluid.

Service and operation

Periodic inspection and cleaning of the DIRTMAG® 1' are necessary to maintain its effectiveness. The collected debris should be removed via the drain port using the hose connection. This process can be carried out without system shutdown, depending on the system configuration. There are no defined service intervals provided in the technical documentation, so maintenance frequency should be determined based on the system’s usage and the level of contamination in the fluid. During inspections, the integrity of the connections and the condition of the body should be checked for signs of wear or damage.

Frequently asked questions

Can the DIRTMAG® 1' be used in both hot and cold water systems?
Yes, it is suitable for systems with operating temperatures between 0 and 90 °C, making it appropriate for both hot and cold water applications.

Is the DIRTMAG® 1' compatible with PVC or copper piping?
It has internal threading and can be connected to metal or plastic piping, provided the thread type matches the system requirements.

Can the DIRTMAG® 1' be installed vertically or horizontally?
Yes, it is designed for both vertical and horizontal installation, providing flexibility in system layout.

How often should the DIRTMAG® 1' be cleaned?
Cleaning frequency depends on the system and fluid conditions. There are no fixed intervals specified, so it should be done as needed based on observed performance.
